In the US, reported on the successful testing of an analogue of the Russian engine RD-180

The founder of the private space company Blue Origin, the creator of the American rocket engine, designed to replace the Russian RD-180, Jeff Bezos announced the success of the first tests.

The first fire tests of our engine BE-4 were successful. The great achievement of the whole Blue Origin team is a very important step!

- wrote Bezos on Twitter.

Recall that the previous bench tests of the BE-4 rocket engine, which is analogous to the Russian RD-180, conducted by Blue Origin in May, ended in failure. Earlier, the company said it was creating three BE-4 work samples. ВE-4 is planned to be installed on the Vulcan rocket - replacement of the Atlas V carrier, where the Russian RD-180 are installed. Two single-chamber BE-4, installed on the first stage of Vulcan carrier, together will allow to develop more traction than one Atlas V two-chamber RD-180 of the first stage, the company says.

Aerojet Rocketdyne is also working on replacing the RD-180. Unlike the BE-4, the AR1 engine is suitable for installation on an operating Atlas V rocket. The company has not yet submitted a working model of the unit, however, in early May 2017 conducted fire tests of the AR1 prechamber.

Two single-chamber BE-4s, mounted on the first stage of the Vulcan carrier, together will allow to develop more traction than one two-chamber RD-180 of the first stage of Atlas V, the company said.

And two two-chamber RD-180s can develop more traction than three single-chamber BE-4s!

[Monos]

Two single-chamber BE-4, mounted on the first stage of the Vulcan carrier, together will allow to develop more traction than one two-chamber RD-180

And three single-chamber BE-4 will develop more power than two BE-4. Dialectics, however!

In fact, it is surprising that the Americans have just achieved at least something. Their technical and financial capabilities are ahead of the rest. And they were able to repeat what they did back in the USSR only now. And two nozzles or three - what difference does it make, engines are compared by their mass, thrust and fuel quantity, and not by the number of nozzles.
And by the way, the video is beautifully shot.

[zoolu350]

A big difference. It is quite difficult to provide high pressure in the combustion chamber, which is why the Soviet school of engine building followed the path of having several combustion chambers in one engine. And there are still doubts about the parameters of the F-1 single-chamber engine - the "Achilles heel" of the entire mattress lunar program, which was suspiciously used only on the Saturn-5 launch vehicle and nowhere else.

[Awaz]

two-chamber and single-chamber - this is not the number of nozzles. This is just the efficiency of using the unit. Two-chamber and give the maximum return.
If it weren’t for politics, then good cooperation could be bungled. They do not know how to make good engines for aircraft in the Russian Federation, but in the USA and the rest of the world for missiles, they would exchange them)))
The United States really didn’t come up with anything really long ago in rocket science. However, like Russia. However, Russia has much more experience and use experience as well. Politics and the stupidity of space officials from Russia are ruining our space achievements and achievements, however, in the USA, too, problems are higher than the roof, although there is no limited money. As far as we have, there are people on whom to stick and they no longer have people, only crooks who only think about dough. Although we take their experience well ..

The title is completely wrong. BE-4 is a completely different engine and is not an analogue of the RD-180. BE-4 is much more promising, since the fuel vapor there is oxygen-methane, and not oxygen-kerosene RG-1. Kerosene RG-1 today is already too complicated and expensive to manufacture. The engines on it are the last century. It is no coincidence that the SpaceX Raptor engine makes oxygen-methane, which is the Bezos BE-4. Kerosene RG-1 will soon disappear just as the synthine disappeared in due time, which even we had to ease a manned ship due to the loss of specific impulse when changing fuel. Sintin simply became an extremely expensive fuel, which is now happening with RG-1 kerosene. And the oxygen-methane fuel pair is more promising from the point of view of future opportunities for the production of fuel in space. To produce methane and oxygen is much easier than kerosene.

“For example, Soyuz rockets, which are made in Samara, now fly on artificially created fuel, because initially only certain grades of oil from specific wells were used to create kerosene for these rockets. Mostly this is oil from the Anastasievo-Troitsky field in the Krasnodar Territory. But oil wells are being depleted, and the kerosene currently used is a mixture of compositions that are extracted from several wells. The coveted brand of RG-1 is obtained through expensive distillation. Experts estimate that the problem of kerosene deficiency will only worsen.

The concept currently being developed at Energomash envisages the development of a single-chamber engine with a thrust of 200 tons using “liquid oxygen - liquefied methane” fuel for the first stage of a promising light class carrier. Space technology in the near future promises to be reusable. And here one more advantage of methane opens. It is cryogenic, which means that it is enough to heat the engine at least to a temperature of -160 Celsius (or better above) and the engine itself will be freed from fuel components. According to experts, it is most suitable for creating reusable launch vehicles. Here is what the chief designer of NPO Energomash Vladimir Chvanov thinks about methane:

- The specific impulse of the engine for LNG is high, but this advantage is leveled by the fact that methane fuel has a lower density, so the total is a slight energy advantage. From a structural point of view, methane is attractive. To free up the cavities of the engine, you only need to go through a cycle of evaporation - that is, the engine is easier to get rid of residual products. Due to this, methane fuel is more acceptable from the point of view of creating a reusable engine and a reusable aircraft.

So why didn’t methane become practically used fuel in Russia? The answer is quite simple. From the beginning of the 80s in the USSR, and then in Russia, not a single new rocket engine was created. All Russian “novelties” are the modernization and renaming of the Soviet heritage. The only honestly created complex - “Angara” - was planned from the very beginning as a kerosene transport. Its alteration will cost a pretty penny. In general, Roscosmos constantly rejects methane projects because it links “good” to at least one such project with “good” to completely restructure the industry from kerosene and heptyl to methane, which is considered a long and expensive undertaking. "

I hope we have some developments going on too. But nothing is heard of any trials. Apparently, we have nothing in iron.

It is unclear where does the oil from a certain field, if kerosene is the first oil cracking product along with the gasoline fraction. From which oil you don’t drive, there will still be kerosene, of course for high-sulfur and paraffin oils you will have to spend more effort, but the kerosene obtained, it is also kerosene in Africa. Another thing is that additives can be added to it.

Here is a comment under an article about a new fuel pair found:

“for the use of cryogenic fuel, it is necessary to make rocket tanks made of composite materials. We several times turned to Roskosmos with our best offers on this technology, but we were refused and we were forced to transfer the technology and the formulation to an American company in California”

There are developments, but they do not reach working samples. Interest in Roskosmos this is not visible.

[SPACE]

However, methane even at a temperature of 91 K (its melting point 90,66 K) has a low density of 455 kg / m3, while the fuel density of methane + oxygen is only 830 kg / m3, which leads to an increase in mass storage costs due to the need to increase the volume of storage tanks components.
The low density of methane + oxygen fuel and the impossibility of oxygen overcooling when using fuel component storage tanks with combined bottoms lead to the fact that for space RBs the time of possible fuel storage in near-Earth space is significantly (by 20% compared to kerosene + oxygen).
Since the melting point of methane is higher than the boiling point of oxygen at a pressure of 1 at (i.e., above 90 K), the use of fuel component storage tanks with combined bottoms even for oxygen boiling at 1 at (and even more so when using supercooled oxygen, which boils at lower pressure) is impossible without the use of inter-tank insulation.
In addition, since the fuel tank is charged with cryogenic methane, it must be insulated from external heat influx, which further increases the mass cost of storing fuel.
All this leads to a significant increase in the mass and dimensions of methane + oxygen fuel storage tanks compared to kerosene + oxygen fuel, which significantly, and in some cases up to zero, reduces the effect that could be obtained from a higher specific impulse of the prototype.

And if we add here the infrastructure, more complex than kerosene, for transporting, storing and refueling missiles with methane. This explains why Roscosmos itself does not bathe about methane, but uses time-proven kerosene. I admit that Russian specialists take their time and just wait for the Americans to be the first to take this dubious path, and in case of any success, they will easily catch up on the beaten track.

Are we so rich that we are now engaged in long-distance flights having very distant prospects in applying their results? And for those AMCs, the States use, practically, the forces of the whole world, including ours, and we will have to do it alone! At that time, the USSR had tore its economy down by engaging in expensive scientific programs, including space ones, which did not bring a quick economic effect. Although the whole world still enjoys many of the results so far, the USSR has disappeared as a state.

[Shadow of darkness]

I see a generation of internet educated! If one crap fails, then a new theory appears with a bunch of "evidence" that again has to be refuted, and so on to infinity. The only reason that justifies the use of methane as rocket fuel is environmental friendliness, but you have to pay for it with a significant reduction in payload. It was still discussed, EMNIP, in the late 80s among rocket scientists. There are no other reasons for using methane and never will be, all the rest is an attempt to cram an idea using methane despite economic inexpediency.

[Warrior-80]

All your conclusions from the category of alternative energy, it is there but it is unprofitable, and the question is about oil and kerosene derivatives, that I have a great mistrust in your words., There are data about problems with kerosene of this brand, I think it’s unlikely

[ventel]

Can I intervene, I'm sorry of course I'm not a rocket or oil specialist. But somewhere I read that in the 20s and 40s all Maykop and Grozninsky oil went to the production of aviation fuel and oils.

[NKT]

Baku and Groznenskaya, since Siberia was not there then, were just conducting reconnaissance in the Volga-Urals, and Krasnodar and the Stavropol Territory remained. But the main production is Baku and Grozny, which is why Hitler was eager for the Caucasus.
In Krasnodar, the wells were abandoned during the retreat and after the war they had to drill again.

And at the expense of rocket fuel and aviation - kerosene as kerosene with only various additives. They seem to be five types for subsonic and two for supersonic aviation.

[Kerensky]

They seem to be five types for subsonic and two for supersonic aviation.

Similarly, with moonshine. Five and two .... Actually running to the toilet can be called a flight or planning ...
I’m not an aviator, unfortunately, but nonetheless ... I constantly deal with kerosene (a slightly alkaline reaction, the basis of the RFS, who knows), well, - kerosene is constantly dehydrated! Any! All types, damn it! I hope they understood and forgave me ...

[Squelcher]

You are right, absolutely oil is first of all a chemical base, and then fuel.

[abrakadabre]

And here one more advantage of methane opens. It is cryogenic, which means that it is enough to heat the engine at least to a temperature of -160 Celsius (or better above) and the engine itself will be freed from fuel components.
...
Due to this, methane fuel is more acceptable from the point of view of creating a reusable engine and a reusable aircraft.

And then at high altitude, if you simply depressurize the tanks, kerosene does not boil away in seconds from ultra-low pressure

[Pivot]

I confirm about oil for rocket fuel, in my opinion, it is produced at the Krasnodar refinery twice a year, there are still specific distillation columns where exactly the most high-calorific fuel is obtained.

Two single-chamber BE-4s are almost 2 times heavier than one taxiway. The thrust to weight ratio is naturally much worse.

I would believe you if I had not worked in such a similar system. I work in large-scale production, which belongs to two people who created all this. However, all production is fragmented into many small and small branches, which seem to be independent, however, they are all boiled in one boiler and subordinate to one center, and even receive wages from one office.
Such a system has its advantages (each department strives to be and is even self-sufficient), however, in some industries and some technological processes it is hardly possible to work in the black.
Therefore, I wouldn’t believe in Boeing so frankly .. The company has a good lobby. Although I do not argue that they know how to work

Import substitution? Country security?
1.RD-180 costs from 11 to 15 000 000 $, or maybe less, because the entire contract with United Launch Services costs 46 million dollars - this is the cost of all five RD-180 (on 2015)
2011 year, Accounts Chamber: In this regard, only in 2008-2009 year the loss from their sales amounted to about 880 million rubles, or almost 68% of all Energomash losses

RD-180 rocket engines sold in the USA at half price

- Accounting Chamber.
They say the contract is very catchy

He then strongly backfired to the Russian military-industrial complex, because when Russia itself needed a “half” engine for the Rus-M and Angara missiles, it turned out that under the terms of the contract, she could not manufacture the RD-180 for her own purposes, but had to purchase it from the American company Pratt & Whitney.

/ therefore RD-180 is not on our RN
suffer from the RD-180B (which was never completed), and on the Angara it was necessary to install not the “half”, but the “quarter” engine of the RD-191 (the expensive PH turned out).

When the printing press is working in the "next room", you will begin to understand the fakes. Understands in business !!! Look do not rejoice greatly, in the sense that - do not strain.

"A strange thing: as soon as the dollar became the world reserve currency in the United States, many talented businessmen appeared ..." ////

The dollar has been the world currency since 1974. But it was from this time that the US economic leadership was shaken. First, Japan crawled out with its "economic miracle."
Then Germany became again the "locomotive of Europe", which led to the European Union and a new strong currency - the euro. And today - China is crushing, becoming the second economy in the world.
So the "printing press" has nothing to do with it. Do not invent absurdities.

This is what you said without thinking. The United States has 20,4 trillion debt, a negative trade balance, if it had not been for the machine to go around the world long ago with an outstretched hand, they put Germany and Japan in a pose and might not ride with the Chinese.

Their duty is internal. The US government owes its own Central Bank.
At stake: salaries of ministers and other government officials, employees of national parks, post offices, museums. Once they have already been kicked out on forced 2-month leave. That's the whole "collapse of America."

[Rt-xnumx]

Own central bank is state Central Bank.
In the USA there is no central state bank.
Its functions are performed private commercial banks.
So the US debt is not domestic, but a group of private bankers.
And if we take into account the phenomenon of dummies, it is generally a duty to some John Heitzmon.

Excuse me, but the investment of China and other Japan in the treasury is also an internal debt ???
And what is the share of treasury in the total debt of the USA to the world?

[opus]

Quote: voyaka uh

Their duty is internal. The US government owes its own Central Bank.

1. External

calculated primarily in its own currency - US dollars. This debt is identical to dollar savings of the foreign sector; its growth rate shows the desire of foreigners to realize savings in US dollars.

2. in America there is no central bank.
There is the Fed
it issues bonds "(debt receipts), nerds buy them for real money (received for some real costs)
well and so on

The debt of the US federal government is equivalent to dollar savings of internal and external private sectors. The rate of its rise or decline shows the dynamics of the needs of the private sector to invest in dollars.

The debts of the American government have a credit rating (AA - according to the Standard & Poors classification), since they are denominated in their own currency - US dollars and for this reason do not have credit risk (the US Federal Reserve System (FRS) has the exclusive right to issue dollars and always can formally settle accounts with creditors on completely different debts, which are denominated in their own currency).
on xnumx g structure


3.Internal Debt is Federal Government Debt
US domestic debts are equal to the country's domestic savings and show the state of the US economy - the volume of economic relationships between its subjects.

All US household debt is more than $ 13 trillion (on 2013)

RD-180 is an American engine. Having bought a patent from Russia and having limited it "for himself" through Pratt & Whitney, the engine became American with all the rights to sell.

C'mon, learn to use Wiki in Russian if you have problems with English.
 “For 2009 was an export engine. All rights to use the RD-180 in the USA belonged to the Space Systems Division of General Dynamics (USA), which in the early 1990s were purchased by Lockheed Martin for use on disposable Atlas (Atlas III and Atlas V) carriers. ...
  Since the goal of the engine program is to launch commercial satellites and satellites of the US government, Pratt & Whitney is considered to be the joint manufacturer of the RD-180 to comply with US legislation. At the moment, all engine production is concentrated in Russia. The sale was carried out by a joint venture between Pratt & Whitney and NPO Energomash called the RD-Amros JV (RD AMROSS). The acquisition and installation were handled by the United Launch Alliance. ”

Have fun, tell me how the program recalculates some coordinates into others. After all, there are not sizes, but pieces.

Yes you never saw a drawing!
Except the sizes. conventions adopted in the ESKD system, the drawings contain technical requirements, a lot of links to Standards, Testing Procedures, etc. ..... Further.
According to the drawings, without technological documentation, no one, no clown can do anything, unless this clown works in a rural forge and the subject of work is a bracket for fastening logs. The volume of technological documentation is several times greater than the volume of design documentation.
Further. Without tools specially made for production, tooling, molds, dies, broaches and automatic settings .... What about automatic programs? Where are they?
Why the hell did you get into a conversation when you don't understand anything in this matter? Analogs of materials do they have? Replacement without testing? Crazy.
And the last.
To what decimal place will you calculate the conversion of inches to mm? And vice versa?

[Roma 1977]

It's not about recounting. It's about working in the metric system on American equipment. In the USSR, in general, the American strategic bomber was copied in the late 40s, and before that it was transferred to the metric system of the air defense for several aircraft, having acquired a license for them from the United States. And this is when there was almost no means of automating the process.

And this is when there was almost no means of automating the process.

No licenses have been acquired. We took advantage of the emergency landings on our territory for several aircraft, they were simply disassembled and copied. Tupolev was forbidden to use them only as an example, forcing him to copy exactly. Even some bracket in the cockpit was copied, the purpose of which no one knew. Full-fledged drawings were made, according to Soviet standards, as a drawing system (MN SCH, the predecessor of the ESKD), and from Soviet materials, scrupulously selected for similar characteristics. A particular headache was in the organization of the manufacture of thin-sheet duralumin for lining.
So the instantaneous organization of the production of other people's constructs using modern equipment is your imagination.

You should know one more subtlety - American equipment works in accordance with American standards - in an inch system that is not fully portable to the metric. Adapting it to the metric system is a different story.

[Roma 1977]

The USSR acquired in the USA a license for the production of the legendary Douglas DC-3 aircraft before the war, which the USSR called PS-84, and later Li-2. The people called them "Douglas." They were produced in large series from 1940 to 1953, they were operated right up to 1973.

Recycle drawings to your standards? To apply their materials by selecting analogues, or having established production that is as similar as possible in terms of characteristics? Yes.
I will say more.
The first tractors we started producing, having bought American Fordsons. Having disassembled seven tractors to the cog, they took the drawings, measured all the details, compiled the tables, calculated the average values, and on this basis began production of the Fordson-Putilovets. At that time, they did not know either the system of tolerances, landings, the principles of interchangeability, typification, and everything that they had gained over the years.

You do not know what you are talking about. No one will ever give all the technical documentation. (By the way, you illiterate call it technological). This underlines your incompetence.
For reference: The volume (weight) of the TECHNICAL documentation in one copy on the SU-27 airplane is equal to the weight of the airplane itself. Note that all technical library documentation - standards, instructions, guidance materials, documentation of equipment, stands, instruments, tools, fixtures and so on, is not included in this kit. I would like to look at your physiognomy, holding 10 tons of paper in an unfamiliar language, in which references to documents unknown to you are recorded. And executed according to the rules you are not aware of. Moreover, in such documentation, there are nevertheless references to the fulfillment of the requirements set forth in top secret documents.

To call a drawing an international document that everyone understands is a journalistic exhaust. I assure you, you will not understand a damn thing, considering the American assembly drawing for some piece of iron.

Of course, I am not a technologist but an ordinary physicist, but I have an idea about the amount of documentation.

In the 1990s, and not that went abroad through the Soros line - people for $ 500 / month translated into English themselves and sent Uncle Sam everything they put their lives on ...

Read it again, you apparently could not understand the first time. Repeating the above is pointless. There is documentation provided to the buyer. Look at its contents in the operating instructions for your coffee grinder. Or a cell phone.
And try to make a copy of these friendly phrases.
A form document is transferred to a complex product, in which the rules and terms for changing the oil, tightening the nuts, and so on are recorded. There, of course, are FIGURES of the components in question. Believe me, the First Division very carefully checks the composition of the documentation sent to the side. And reports violations.

No, you inattentively read it. The relationship between the amers and Energomash during the development of the RD-180 differed from the relationship between the buyer and seller of the car in the cabin.

Long ago there were super-cool Shuttles. Died out. Let’s guess why they don’t fly into space today on the Shuttles?
And then it was just like this: "you and the Shuttles did not work out, and here you are obkhayu ..". (The USSR did not make it with the Shuttles). One-to-one as it is now with the Falcons.

[eklmn]

“Let’s guess why they don’t fly into space on the Shuttles now?”
    Guessing is not even necessary. Google must be asked: 
Why did NASA stop the shuttle program?
  answer:
Discovery was the first of the three active space shuttles to be retired, completing its final mission on March 9, 2011; Endeavor did so on June 1. The final shuttle mission was completed with the landing of Atlantis on July 21, 2011, closing the 30-year Space Shuttle program.
  Discovery was the first to fly its resource in March 2011 (25 flights), Endeavor in June (33 flights), and Atlantis in July (29 flights). And NASA closed its 30-year program. Although each spacecraft was designed for 100 flights, NASA closed it due to the high cost.

[SergeBS]

In fact, in the 20th century it was calculated: the Shuttle will economically outperform Progress and Energy, starting every 2 weeks. On an equal footing - starting at least once a month (well, the rules for replacing blocks, changing fuel, etc.). It wasn’t.
Those. The "super-efficient" Shuttle just turned out to be more expensive.

Better, list what is done. Moreover, not in proclamations about ... in the near future, but really. PRE-ORDERED CAR? Two Falcons launched a second time? With an interval of a year. Is it- REPEATED use? Consumers do not need bench tests, but full implementation. Landings of the first stage are absolutely unnecessary for the consumer. This is the collection of scrap metal at the expense of the buyer starts. Let's get a list. Stop talking.

For all the times. I will not become like your stupidity, I will not begin to search and compile lists for ALL flights of Soviet and Russian carriers.

By the way, and your cosm. the agency should also be officially proud of its achievements and collect them in one pile, so that it would be easier for patriots to rummage through the achievements.
  Now about the used rockets. There were three launches so far and in all cases the rocket was planted again. Now it depends on the customers: they want it on a used one - 40% cheaper, but insurance is higher, they want it on a new one - the price is known (on the same site), but the insurance is cheaper. What a future launch is a trade secret.

You see, knowledge of the English language does not save you from having to look for the reasons for only three starts again. And with a break, not nearly worth the promise of the Mask, 24 hours.
We affirm that this is a victory.

There is success, but it does not solve anything in the history of astronautics. In a hurry to get new pies, Musk will slowly lower this project on the brakes, replacing the more grandiose congressmen who did not impose in their teeth. For example, heavy reusable, and then superheavy, reusable.
In his strategy, Tamerlane’s strategy is seen - to increase pressure, even if he depletes resources.

eklmn "overlooked" the MAIN argument: "that's when Falcon will be FAVORABLE."
Launching a used spacecraft for the second time is not a trick (see Shuttles), but to make it cheaper than a one-time one is a problem (the same Shuttle).
About reliability - also "lost sight of" (and again the Shuttles, as an example).

In order not to be surprised, you need to know.
Musk did not invent ANYTHING. He bought the designers who lost their jobs after the closure of the lunar program, and picked up reusable Shuttles after the closure. He received patents for free, and hardware left over from NASA programs. He received two starting complexes. He received several billion to develop his "reusable" missile program. He builds financial pyramids, taunting gullible fellow citizens and lobbying his interests through the congressmen hired by him.
Note- EVERYONE of his next promise is more grandiose than the previous one. From the reusable falcons, usual for carrying capacity, he passes to the promise to build super heavy.
From passenger electric vehicles to heavy duty trucks. From near-moon flights to near-Martian. From vacuum transport for passengers to vacuum transport for passengers in cars, with transportation from the place of “pick-up” in the car to the vacuum transport corridor at the specified address to the place of disembarkation. From free Internet through 450 of its satellites to free Internet through 1500 of its satellites. From a home storage power station serving an emergency in an apartment to a home power station with electricity being returned to the grid.

The excellent results obtained at the stand are far from the actual launch of the medium. Do not remember. What ended the two launches of Falcons? Accident Where? In oxygen tanks, in which there were compartments for helium. Interestingly, they stand exactly on the stands, or of a different design? Different.
What did I want to say?
The trouble-free operation of the carrier depends on a billion reasons, and not only on the operation of the engines. Incorrectly installed sensor .... Or fastening a completely harmless detail, which does not experience vibration on the stand, in real life can break off and be the cause.

Into a low elliptical orbit on their Shavit rockets. And now the cost (and manufacturing complexity) of the reconnaissance satellite is much higher than the cost of the launch vehicle.

The point is not reliability, but overload during take-off and coordination of the inhabited ship and LV.

Great answer. It's not about reliability, but overload. Is it really so difficult to slow down the pace in engines throttled everywhere already and provide the load endured for a person? As it turns out, everything is simple. And the emergency rescue system, and what is more, providing rescue over the entire period from the start of the launch to putting it into orbit? Didn’t you forget about it, or for you man is not a goal, but a means? The mass of the inhabited ship is somewhat different from the cargo. The mass of the descent ship is somewhat different from the cargo. Add up all the components of this and realize that to raise the same 20 tons, but with a person is a completely different cost, and means.

[aiw]

Yes, let's throttle the Russian Railways - as a result, it will not work in + mode; the launch vehicle will not have enough fuel to launch the launch vehicle into orbit. Of course, for the conclusion of a person, the highest reliability is needed, but everything else is not a pity - nehai beats through time.

The mass of the inhabited ship is slightly different from the cargo

There are very different trucks and very different inhabited spacecraft. Excuse me what exactly did you design? Judging by your estimates of Space X, ignorance of the Israeli space program and other pearls is clearly not space technology ...

You see. One had only to think a little, it turned out that the resource of the truck in human flight mode may not be enough, and reliability is not enough. For some reason, the rescue systems were not noticed. Lack of trucks. But this is, by the way, written from my scum.

[aiw]

Twenty five again for money fish ...

the truck’s resource in human flight mode may not be enough, and reliability is not enough.

And here is the resource and reliability? If for a truck you limit overloads to a level acceptable for people to withdraw, then this leads to a radical decrease in payload. Only ballistics and nothing more. The rescue system fits well with the mass of payloads - they don’t put it on trucks because it doesn’t make sense to bother like that for cargo (if it works, the satellite will go to waste anyway).

Not two, three, but millions of human lives depend on the reliability of ICBM operation, however, no one has taken people into outer space long ago removed from ICBM duty, although everything is OK with reliability. Oops?

I will say that my work was related to both civilian products and the military.

PS. The overload restriction does not appear on all LVs - say, Proton was planned to be used for a manned lunar mission, Zenit was planned as a replacement for the Union. Heavy trucks have acceptable overloads but are redundant for manned low Earth orbit flights.

Let's see how much our first Russian aircraft carrier will cut, before the year 2080, in the end they will make a trough, of cheap Chinese parts, built on Chinese equipment, the Goliath crane is Chinese bought it.
Alas, Putin has no ambitions.

The first fire tests of our BE-4 engine were successful. A huge achievement for the whole Blue Origin team, this is a very important step

Well, that is, not the first, but the second. And, most importantly, the question is the price of the finished product. And it can turn out like with a super-duper fighter.

Toluo serial super-duper fighter is already cheaper than the latest modifications of the F-16 and F15.

[Berkut24]

Currently, all production fighters are significantly more expensive than the F-22. Do not look at the price tag. Firstly, all F-35 users continue to pay for improvements and elimination of jambs. Secondly, as I understand it, you also do not take into account the money for its development. The US National Guard chose to order the F-18 instead of the F-35 precisely for price reasons. And yes, the life cycle of all built for the United States will cost 1,5 trillion. dollars. If the F-35 was cheaper than the F-16, then it would have stood in line. In the meantime, the US allies are either abandoning it or drastically cutting down on proposed purchases.

Yes, and for the F-16 there is no special queue. Mostly contracts for the modernization of long-built versions.

[Berkut24]

Not yet. This is not the final price, but only a promise to the Senate. marketing, so to speak.

This price is included in every aircraft built. And the larger the series, the lower these costs in a single product. And the F-35 series is planned in more than 1000 pieces or even 2000.

You probably do not know that the Pentagon has a budget for promising developments. So, it is spent as a separate article for new projects of wunder-waffles, which kind of should ensure lifelong world domination. So to speak, venture financing. On the F-35 was added more than once or more, and this is tens of billions of dollars each time, because the Pentagon is now held hostage by the manufacturer. The old park is gradually being decommissioned, but there’s nothing to replace properly.
Previously, plans for rearmament included 2500 aircraft, but the Pentagon is now instead ordering older models or spending on upgrading the existing fleet. There will no longer be 2500, or 2000, or perhaps 1000. The Allies also cut orders. There will be no declared price.

The US National Guard is not an indicator in the acquisition of weapons.
We must look at the combat units of the Navy and the ILC.

Well, of those 2500, a significant part was attributable to NG. The combat units are still looking askance at the "conditionally combat" vehicles and are still wondering how many more "conditionally combat" they need right now.

Yes, and for the F-16 there is no special queue. Mostly contracts for the modernization of long-built versions.

And it is right. It already exists and their effectiveness is still significantly higher than "conditionally combat."

He told me what their problem was with the nozzle. It all the time either collapsed or did not reach the necessary characteristics. In short, quite by accident, according to him, the nth instance of the nozzle issued the necessary and did not collapse. And then they copied this copy for mass production.

I can’t understand, on which engines flew to the moon? If they managed to make "lunar", then why are they stuck on weaker taxiways?

The lunar program was announced from the national humiliation of America, which they experienced as a result of the victories of the USSR in space exploration. Nightmare money was invested in the program, these works were given preferences on all floors, THOUSAND firms, firms, and almost workshops for space orders were connected. We must pay tribute - the amazing organizers of the Americans. Wrap up the most complex and global plans. And the ability to achieve. Of course, bottomless financing will help them.
The long-term work of this armada was successful. I am inclined to think that they, nevertheless, flew to the Moon, although there is another opinion. But this is not what I am talking about.
Result: The program is completed. The Saturn 5 Carrier has nothing more to do. They lifted Skylab into orbit, a station weighing 80 tons, with one launch, but they could not even use it. They drove there only three expeditions. And in the end, flooded. The mass of firms, firms, workshops went about their usual business. Make money. Equipment, stands, laboratories, equipment, tools were sold. It’s only we who microfilmed the most important products, handing these microfiches into storage funds. It was only in the USSR that it was possible to preserve equipment, leaving it on the balance sheet and paying taxes and depreciation, since it was forbidden to write off it. EVERYTHING belonged to the state. . It is impossible to force a private trader to do this.
So, very quickly, they lost both documentation, equipment and specialists, rebuilding factories and workshops to produce the required products. So, what they could successfully do THEN, today they do not know how.
Restore old, materials, equipment, drawings are much more expensive. than to do new on a new basis.
Thousands of sheets of drawings of the rocket itself turn into millions of sheets of technological processes, drawings of stands, machine tools, equipment, instruments, tools and everything else.

[Justme]

Among my friends was a specialist calculator for strength. He rubbed a lot among a similar audience of ours, who used mainly Nastran. Well, they told him there that when the Americans wanted to use our rocket engines, they said - ".. and we should have - everything is certified, everything is right .. prove that your engines are right .." And how is it done - the design documentation is taken, .. it is explained in detail what is done and done there .. all of this is then thrust into Nastran .. Nastran chews it .. and then Nastran says "Okay" ..
When the “OK” from Nastran is received, all this heap is taken and dragged to the Americans ..
And now the Americans are saying - “OK”

[Curious]

"When the OK is received from Nastran, all this heap is taken and dragged along to the Americans."
To drag early. Still need to get "OK" from Thermal and Flow. Then that's all.

[Justme]

Well, if you still help them with gas-dynamic profiling and adjust the modeling of heat flows - this is generally gorgeous.

[Curious]

It is as if logical. I am not a specialist in rocket engines, but designing it is certainly not starting with strength calculations.

[Justme]

In such developments, everything is at its limit and every similar engineering and scientific field where analysis is carried out also contains a fairly complete reflection of everything else ... But in terms of complexity, dynamic strength and its analysis are very far from the static and quasi-static case.

[Curious]

I have a question, because dynamic loads are quite common when calculating various structural elements, including metallurgical units.

[Justme]

In the initial conversation, my friend talked only about strength calculation .. But ..
If in our turbochargers then the key safety factor was 1.6..1.7, we counted and measured turbine blades up to the seventh mode.
Aviation engineers already take into account dozens of vibration modes of turbine blades ..
And it is obvious that the safety margin of a rocket engine in problem areas will be 5-15%, that is, to calculate the dynamic strength, an absolutely accurate description of the dynamics of work is needed.

And these are those who have already "flown" to the moon. Of course, this is an important step not only for Blue Origin, but also for the United States in general.

NPO Energomash respects the development of Blue Origin, but notes that the engine, which should replace the Russian RD-180, must go a long way before it can be used in missiles, said Igor Arbuzov, General Director of NPO Energomash .

The Americans paid for the supply of engines before the 2019 EMNIP. In any case, over the past couple of years they will finish. Even taking into account the fact that the engine has less thrust than the RD-180 it is methane. And in this case, it is cheaper than hydrogen, although it is slightly inferior to hydrogen in energy and exceeds kerosene
At least we still do not have such an engine, although work has been going on for 10 years

Quote: APASUS

For the series to be launched, the engine for such a machine should run several hundred hours to confirm its suitability. As long as these are only successful tests, the final completion will still be in 2 years.

Of course. No one says that tomorrow there will be an engine. Moreover, the first launch of the Volcano is planned for the end of 2019. Moreover, given the fact that some difficulties are possible or if a delay occurs, there is an alternative with the AR-1 (kerosene) engine. The media is intended to replace Delta-4 and Atlas-5.

Quote: Orel

Quote: СРЦ П-15

I don’t understand one thing, if they have super-duper cool falcons that are also cheap, why are they trying to make new, more expensive rockets?

The title is completely wrong. BE-4 is a completely different engine and is not an analogue of the RD-180. BE-4 is much more promising, since the fuel vapor there is oxygen-methane, and not oxygen-kerosene RG-1. Kerosene RG-1 today is already too complicated and expensive to manufacture. The engines on it are the last century. It is no coincidence that the SpaceX Raptor engine makes oxygen-methane, which is the Bezos BE-4. Kerosene RG-1 will soon disappear just as the synthine disappeared in due time, which even we had to ease a manned ship due to the loss of specific impulse when changing fuel. Sintin simply became an extremely expensive fuel, which is now happening with RG-1 kerosene. And the oxygen-methane fuel pair is more promising from the point of view of future opportunities for the production of fuel in space. To produce methane and oxygen is much easier than kerosene.

“For example, Soyuz rockets, which are made in Samara, now fly on artificially created fuel, because initially only certain grades of oil from specific wells were used to create kerosene for these rockets. Mostly this is oil from the Anastasievo-Troitsky field in the Krasnodar Territory. But oil wells are being depleted, and the kerosene currently used is a mixture of compositions that are extracted from several wells. The coveted brand of RG-1 is obtained through expensive distillation. Experts estimate that the problem of kerosene deficiency will only worsen.

The concept currently being developed at Energomash envisages the development of a single-chamber engine with a thrust of 200 tons using “liquid oxygen - liquefied methane” fuel for the first stage of a promising light class carrier. Space technology in the near future promises to be reusable. And here one more advantage of methane opens. It is cryogenic, which means that it is enough to heat the engine at least to a temperature of -160 Celsius (or better above) and the engine itself will be freed from fuel components. According to experts, it is most suitable for creating reusable launch vehicles. Here is what the chief designer of NPO Energomash Vladimir Chvanov thinks about methane:

- The specific impulse of the engine for LNG is high, but this advantage is leveled by the fact that methane fuel has a lower density, so the total is a slight energy advantage. From a structural point of view, methane is attractive. To free up the cavities of the engine, you only need to go through a cycle of evaporation - that is, the engine is easier to get rid of residual products. Due to this, methane fuel is more acceptable from the point of view of creating a reusable engine and a reusable aircraft.

So why didn’t methane become practically used fuel in Russia? The answer is quite simple. From the beginning of the 80s in the USSR, and then in Russia, not a single new rocket engine was created. All Russian “novelties” are the modernization and renaming of the Soviet heritage. The only honestly created complex - “Angara” - was planned from the very beginning as a kerosene transport. Its alteration will cost a pretty penny. In general, Roscosmos constantly rejects methane projects because it links “good” to at least one such project with “good” to completely restructure the industry from kerosene and heptyl to methane, which is considered a long and expensive undertaking. "

I hope we have some developments going on too. But nothing is heard of any trials. Apparently, we have nothing in iron.

Great koment. Truthful. Often, Soviet developments are presented as Russian, which is fundamentally wrong.

[Gormenghast]

Different engines. On different fuels. Accordingly, the methane thrust ratio is unknown, not reported. As well as the specific impulse is carefully hidden.

Methane fuel has a lower density than kerosene; the tanks are heavier, the rocket has a smaller recoil.

Output: yes, in terms of traction, this engine can replace the RD-180.
Whether he will be better is doubtful; especially considering that it is proposed to compare warm with soft.

And still there is a cost. And then a certain ratio comes into force. The engine is cheap if the costs of its creation are nationalized, and the profit from use is privatized.
The costs of creating the RD-180 were successfully nationalized in the USSR - as this is half of the Soviet RD-170 engine. Now the cost of this engine is only for its manufacture. According to the Bezos engine, it is alleged that it was created "without the participation of the state." So, the costs of development, testing, certification Bezos must "beat off"at the production stage; transfer part of the costs to the final cost of the engine.

The new law of capitalism, invented not by Marx but by Obama and Co., will come into force. A totalitarian product is bad, regardless of its value; democratic goods - a priori good. This also applies to gas and rocket engines.

In a normal competitive economy, the principle will not work - as long as the United States has non-economic advantages, in the form of a dollar, sixth fleet, etc.

Bezos creates a promising engine, but you can put it on the Atlases only by force, by order of the State Department.

At present, the plans include the modernization of the RD-191 engine to the RD-191M version for the Angara-5M launch vehicle, the resumption of production of the modernized RD-171MV engines and the new two-chamber RD0124MS for the Soyuz-5 launch vehicle. Last year, a series of fire tests of the RD0162D2A oxygen-methane engine with a thrust of 40 tons was conducted, and a preliminary design for an oxygen-methane engine with a thrust of 85 tons was also developed.

very slowly ... as if they specially give time to everyone to catch up with Soviet developments in the space and rocket field

[slipped]

In order for the engine with LNG fuel to fly, you need to make a decision to create a carrier for it, the engines themselves do not fly into space). So far, Samara has developed a preliminary project for a carrier with the code name "Soyuz-7" (formerly Soyuz-5.1), here we apply LNG. But then again, until such a carrier is in demand by our space industry. More or less, everything should change with the transition to new carriers designed for heavier payloads at the beginning of the next decade.

[Vadim237]

Only these heavy carriers will be at the beginning of the next decade only in the USA, SLS and Falcon Heavy, and ours will be created already in 2026, but most likely it will be 2035, and there it will no longer be needed, since all orders go to competitors.

[slipped]

Again, carriers do not fly on their own - they need a payload. For SLS, such a PN, is the construction of a near-moon station, and flights will be rare, what to carry to the Falcon Heavy is a big question. At the same time, the lighter Angara-A5M can also be used to deliver goods to the near-moon station - it will deliver 4-7 tons there, for example, the new Progress or, in the A5V version, 10-ton research modules based on a pressurized compartment NEM. STK is planned for the first launch in 2028, however, the creation of Soyuz-5 will show how long this period will be sustained. As for orders and competitors, superheavy carriers have nothing to do with this.

[Vadim237]

Well, let's say, not all the salt is in the means of excretion, but in the delivery price and marketing policy. So far, here everything is moving in the right direction. “Proton-L” is being created on Khrunichev by launch in 2019 and there is already a contract for it - thereby reducing the cost of withdrawing payloads at the most popular weight of 5500 kg per GPO until 2025. An advance project is being drawn up for Soyuz-5 (will be presented in November), which will replace it in 2022. And small and microsatellites - the launch companies of Glavkosmos have already begun with the withdrawal of additional payloads in launches of Soyuz-2.

Yes SHCHAZZ! They will earn on space politics. But not in space.
In space, as in fundamental science, it is impossible to make money. Like the Collider, for example. "Rich space tourists", etc. investments in space programs will not make profitable.
If quite simply, then until now civil aviation of any country is subsidized by the country, i.e. in the "transfer" - some fly, but everyone pays (those who pay "for profit + amortization of the aircraft + infrastructure + fuel + discount on fuel", and others - "for a discount on fuel"). Due to preferential prices for kerosene. And this is "just" civil aviation.

... Musk did not invent ANYTHING. He bought the designers who lost their jobs after the closure of the lunar program, and picked up reusable Shuttles after the closure. He received patents for free, and hardware left over from NASA programs. He received two starting complexes. He received several billion to develop his "reusable" missile program. He builds financial pyramids, taunting gullible fellow citizens and lobbying his interests through the congressmen hired by him.

... all this is about nothing, even ideas expressed on paper will remain ideas, the implementation mechanism is important. In this system, the turner Uncle Vasya, or John in the American version, will probably be the most important link. To make one taxiway is one thing, and to make twenty is another. For example, Tupolev had a B-29 for the sample ... how many years it took to put it on the series, after the Americans studied the stolen MIG-25 in Japan, and when they saw a stainless steel in place of titanium, they generally recognized that they did not understand how it can fly. So let them have fun ... if you suffer for a long time, something happens, Russian wisdom confirmed by Chinese practice.

When you worked as a constructor, you would understand that copying someone else's is a more difficult task than using something that you still don’t know, or what you doubt. To understand someone else's, you need to understand why this is done. It is much simpler to compare what you already know and the hint, as you did another. The constructor from God was pushed, the tyrant and the pithecanthropus from aviation. There can be no greater harm to aviation from this. Borrowing- ALWAYS stay on the sidelines, even if successful. Talent sometimes needs a simple hint, and he leaps into the future. Do not catch up, but get ahead. And for this it is impossible to steer from party and other offices.

Why so courageous in judgments? Turner has never been a decisive link.
With all due respect to him. A good turner will certainly appear in five years. Be an interesting job, adequate housing and the prospect of a decent income. It is the perspective in which he will believe. Earning today, and the one that was disqualified in the last century, is not progress, but a brake on updating. A scientist who has the opportunity to realize his dreams. Constructor Technologist. And not the security guard, accountant, lawyer, whom we forged during the years of the damned collapse beyond measure.

Well, let's wait five ... when a new turner is born ... and let everything wait.

dubovitskiy.1947,
At the moment, we were discussing why manned ships are not being brought out by trucks.

You argued that there were problems with reliability, I argued that with high overload and load balancing with the LV - I already wrote there above that for heavy trucks overload is acceptable, but for them there simply aren't enough heavy manned ships that would justify the launch of such a colossus. Not yet.
And so there were plans to use trucks for manned launches, i.e. the main problem with load balancing.

If we talk about the trials of the new dvigla, then there is nothing to discuss - the Americans will bring it to mind. All the cries of our jingoistic patriots that they say they cannot repeat ... they don’t repeat, they do their own thing. What they did not do before - but there was no need, the RD-180 suited them for the price / quality.

I have no doubt that they will. Maybe very soon.
But here are plans from a real achievement, I have been able to distinguish for a long time. You have yet to do it. And when this happens, it is up to you.

[aiw]

Oh wei .... again this mentoring tone. How do you know what my experience in this area is?

You have already distinguished Mask's plans from achievements regarding the reuse of the first stage - it turned out silly and funny for you.

If he had even been in its infancy, they would not have written nonsense.
They fed me with plans all my life. Therefore, I do not believe anyone, especially if they smell like dough. The result is evaluated.
The result is three re-launched with a break of one year. Plans - 100 launches with a period of 24 hours.
Something tells me that before fulfillment it is like to Mongolia on karachik.
It is much easier to start silent and build new ones, with a new rocket, and with a new object. What is more grandiose? Mars - the passed stage, promised and paid. Forget it.

Unfinished work is not shown to everyone. For 100 launches, we still need to find customers, so far Musk has confidently pushed Roskosmos into the far corner.

I'm leaving this site, the moderators here are not adequate.

Then do not groan with delight, having received intermediate results.
Which can not be called even intermediate.
Intermediate is the achieved stage stipulated in the plans. The first stage is three flights of one carrier with an interval of a year, the second is ten with an interval of a month ....
Landing on the ground or platform without secondary launches is the collection of scrap metal at the expense of the customer.
These are not the results; this is an ohmurilovka.

Yeah. Bring to mind YOUR copy of the RD-180. And sho?
Copying other people's achievements at the cost of wild investments - you will not get ahead.
The same China easily catches up cheap electronics - there are factories with technologies, there is no need to copy technologies. But with aircraft engines is a problem. There are no factories with ready-made technologies, and their copies have a resource an order of magnitude smaller and with traction also "slightly worse." But everyone around is shouting - "a super-technological country."

Can you distinguish a copy from an analog? Tu4 is a copy of the B-29, Tu-95 is an analogue of the B-52.

Yeah. And the 600th Mercedes is an analogue of the Ford T3, for example.
And in general ALL cars are an analogue of a cart (what’s there, what - four wheels, this means an analogue).
And what about the “TTX analogue” is a bit “cooler” - it doesn’t matter. The analogue! The wings are similar, the engines too. So arguing, you can quite simply yell: "all modern diesel engines are analogues of the Rudolph Diesel engine." And that TTX "slightly different" - does not count.
