The first rocket engine delivered in the United States to replace the Russian RD-180

The first American rocket engine BE-4 manufactured by Blue Origin, designed to replace the Russian RD-180 in the future, was delivered to the United Launch Alliance. This was reported by the company itself on its page on Twitter.

The BE-4 engine for the Vulcan Centaur rocket was delivered to a facility in Decatur, Alabama. ULA's next-generation rocket is planned to be launched in 2021

- said in a statement.

At the same time, it is specified that the engine is not serial, it is planned to be used for testing together with a launch vehicle. The second BE-4 engine should be delivered before the end of July this year.

Recall that the American BE-4 rocket engines are planned to be used in the first stage of the Vulkan launch vehicle, which should replace the Atlas family of rockets equipped with the Russian RD-180.

At the same time, it is noted that although the US Congress calls for a complete abandonment of the Russian RD-180, this is unlikely to be possible until 2024. The main reason is the high cost of the American analogue and the unpreparedness for its mass production. Since 1999, Russia has supplied the USA with 116 RD-180 rocket engines.

It hasn't gone anywhere, it is in the museum, because, firstly, it is hydrogen, which, in general, will do for a flight to the moon in the 70s, but for launching satellites and cargo to the ISS in our time - too much. Even Russia is now switching to environmentally friendly "kerosene" rockets.

what is the first economy

This is the first economy in the world that gave birth to the counterpart RD-180 for more than 30 years! This is with industrial capacities, technologies and money. By the way, the RD-180 is one of the most reliable engines in the world. But to the fact that the mattresses are cut out, there are very big questions about reliability.

[snucerist]

In addition to reliability, any device needs more demand. Otherwise, what is the point of producing it?
Now tell me, pliz, where in the world is this super-reliable RD-180 engine used?
In Russia, there is no use for him, because under him there is stupidly no carrier. And will not be. Rogozin tales about the Angara -6 are already tired.
RD-180 is taken only by the States. And only for the Atlas carrier. More in the world it is not in demand. The Atlas program will be closed; even NASA is tired of containing such an expensive project.
What will happen next with the RD-180? Which is reliable but no one needs?

Such a carrier as Angara-6 does not exist in nature. It is planned to create the Soyuz-6 and Yenisei carriers, which use the RD-180MV engine in their composition.

I wrote above. Moreover, the price of this engine as a result of modernization has been significantly reduced.

[snucerist]

The amendment is accepted. Of course, Soyuz-6 is just a reservation.
Nevertheless, the tale now about Soyuz-6 does not become a reality from this. Like the tale of the whole Angara family. Like everything, however, Rogozin said.
The epic with the Federation-Eagle will be repeated in detail.
The fact that the price of the engine is reduced does not mean that it has become more in demand. Zimbabwe and Venezuela will not need him.
In Russia, there is no use for him. And will not be. As there will be no Union-6.
Atlas program will be closed.
The remaining engines will go to scrap. Everything is simple.
We cannot understand one simple thing: Rogozin says, and Musk does.

Half of the RD-180 (one combustion chamber) is the RD-190 engine. Unification is called. So that the pump and piping can go to the warehouse, and the combustion chamber can be installed on some engine from the same line. And even then it is unlikely: the NK-33 engines have been in the warehouse for decades, and still correspond to the advanced engines, I am sure, and the same can be said about the RD-180 (not today, so tomorrow it will find its client)

[snucerist]

To begin with, for some time, the Americans had no reason to create an analogue of the RD-180. If someone does not know, it was originally created for the needs of the United States.
For his "dad" RD-170, there was no use in the Union at all after the inglorious death of the initially failed Energia-Buran project. For there was no carrier for it. And now there is not. And there never will be. Never.
The half-cut "dad" agreed to take the United States. In Russia, it was also not used for the simple reason that there was no carrier for it. So Energomash should bow to the States in the belt for the fact that at least someone takes his goods, because in Russia itself, the RD-180 cannot be adapted to something worthwhile (fantasies about Union-6 are from the realm of the fairy tales of Baron Munchausen).
And the States take it only for the Atlases, no one else needs it there. In Russia, I repeat, no one needs him at all. By the way, Musk will soon close this shop, for Atlases are expensive, even by NASA standards. Is the fate of the RD-180 clear?
Junk
Although the engine for its time was excellent.
But BE-4 is methane. This is a different generation.
And Musk's SpaceX Raptor has already surpassed the RD-180 in performance. This is despite the fact that the fraudster Musk, as everyone knows, does not stand still like Energomash, is not stuck in the last century, but is constantly moving forward.
Output? It seems to be unambiguous.

We must unanimously forget about the 84 launches of the Zenit rocket, right? RD-170 is the engine of the parablock of the Energia launch vehicle, the RD-171 is its modification for the Zenit-2 launch vehicle, and the RD-171M is a modification for the SL. RD-171MV is a radically revised modification for the Soyuz-5 launch vehicle.

So there you have a specific answer.

In Russia, two carriers are currently in operation. "Soyuz-2" of various modifications and "Proton-M" of the third and fourth phases of modernization for which they are preparing to replace the missiles of the "Angara" series. On these media NOT the RD-180 engine is installed, since it was developed for the American carrier Atlas, which successfully completed 90 accident-free launches.

A new RD-180MV engine has been developed in Russia for installation on promising carriers.

With the current launch program there until the age of 30. Atlas also decided to market.

NPO Energomash sold Russian rocket engines RD-180 to the US for half the cost of their production, Sergei Ryabukhin, an auditor of the RF Accounts Chamber (JV), told reporters that the JV had come to this conclusion after checking the activities of the research and production association.

[U-58]

But Toko does not need to think that Energomash itself sets the price for the engine for Americans.
On the contrary, in this story from the very beginning, from the time of Yeltsin and the Gor-Chernomyrdin commission, Energomash is, firstly, a party subordinate to the government (RF, for a minute) and, secondly, the affected party. It is in terms of prices for a) technology transferred and b) for delivered products.
And the fact that after raking out the foreign currency proceeds by the government, Energomash fell crumbs to keep the company afloat for 25 years after happiness

[slipped]

Quote: Avior

880 million loss

The loss has long been returned a hundredfold.

[Gennady Fomkin]

Academician, General Director of NPO Energomash - Boris Katorgin wrote that the States spent 4 years to master and launch the RD-180, but they could not have created this production even in 10 years, it is so unique. As a result, the USA and NASA decided to go by creating your own engine, so as not to depend on Russia. NASA's call was answered by SpaceX, Orbital ATK, Sierra Nevada and Boeing. And also companies: Blue Origin, in 2011, it began work on the reusable BE-4 engine (thrust 249 tf, methane / oxygen fuel, two BE-4s will be installed on the rocket), and Aerojet Rocketdyne has been creating AR- 2010 (thrust 1 tf, kerosene / oxygen fuel, two AR-226s will be installed on the rocket). Until 1, Rocketdyne was a division of Pratt & Whitney. It was "Rocketdyne" that the RS-2013 rocket engine was developed for the Shuttle program, in principle it can be considered a replacement for the RD-25 engine, but only its cost is 180 million dollars and hydrogen / oxygen fuel, which does not allow the use of RS-65 for launching the Atlas rocket, besides it is very complex and explosive. In principle, it has long been outdated.

[Blackmokona]

Something you wrote in general left.
First, only two responded to the call to replace the RD-180. This is the Roquetdine with the AR-1 engine, and the BO with the BE-4 engine that they began to develop many years before the order, for use in their New Glen rocket, and the supply of ULA engines is simply an opportunity to get the dough out for business.
Musk, with his SpaceX, is absolutely not interested in selling his Merlin and Raptor, since he wants to squeeze out all the launches for himself.

[donavi49]

Not. Generally there is fun. NASA started the program, and all sorts of startups climbed into it, without anything, but give me the money. In the end, it didn’t work out. The aerojet made the AR-1, but it’s difficult / expensive to convert the Atlas to it. Plus, the unique operating time for the accident is lost and all certifications fly right away. It is not worth it. Like a straw for a rainy day. As a result, in order not to be lost, now Aerojet is trying to sell these engines to private owners, in particular fireflies.

Bezos has long been working on methane for his launch vehicle. And then there was the opportunity to enter into a partnership in YULA, get money, experience and other useful things. They broke due to the LNG concept at the competition AR-1 for the first stage of the Volcano-Centaurus and took the contract. But this is not a specially designed engine to replace the RD-180, it is a private trader who wants to gobble up commercial launches like Mask and a mask too (his system is a little more progressive than 9ka and FH).

The rest did not respond. The orbital generally bent and began to make Omega on HTPB (solid fuel) as requested by the new owner (he makes these engines Castor).

The RS 25 is explosive - but for all the years of operation on the Shuttles it never exploded.

This is not an analogue of the RD180. And the other direction is methane engines. Here Roscosmos is already forced to catch up. And the gap is decent.

In the Voronezh missile center engine tests already conducted a series of fire tests of a model gas generator. It will also become an element of RD-0177. Among others, specialists have studied the processes of mixture formation with various versions of the nozzle head.

According to the developers, the choice of several design and technological solutions was made based on the requirements for increased reliability of the gas generator and the possibility of its multiple use in the engine. KBHA chief designer Victor Gorokhov said that the next task is to develop another key unit - the combustion chamber. Only then to manufacture and assembly of a prototype RD-0177 oxygen-methane engine.

“The test results and the results obtained gave an obvious understanding of the best gas generator design that should be used in the engine being created. The next stage of work, which we have already begun and are planning to carry out in the near future, is the development of another key unit - the combustion chamber. After that, it will be possible to proceed to the manufacture and assembly of a prototype of the RD-0177 oxygen-methane engine, ”experts say.

That is, there is not even a prototype yet. Whereas BE-4 is already in the pre-series for Centaurus and Glen. And he passed the main bench tests.

1) So this is Musk, he constantly loves such tricks.
2) The raptor has nothing to do with RS-25

Ps: According to your link, the price of the Raptor is 2 million dollars.

We must pay tribute to the Mask, the Raptor is a good engine.

[Blackmokona]

1) Because it's a complicated thing.
2) Yes, I made a mistake.

The 1997 agreement provided for the supply of 101 RD-180 engines for a total amount of about $ 1 billion

So the cost was 18-20 million dollars.

The raptor is made according to the scheme "with complete gasification of components". This is the only engine of this kind that has successfully lifted off the ground. In the RS-25, only fuel with a small part of the oxidizer passes through the gas generator, while in the Raptor, all the fuel passes.

[mikhailovich22]

The Raptor has two gas generators: reducing and oxidizing. Raptor differs from RS-25 in that an oxidizing gas generator is added. Before the Raptor, Americans could not create oxidative gas generators, unlike the USSR. The Americans do not have closed-cycle engines with a kerosene-oxygen fuel pair.
A circuit similar to the Raptor was developed back on RD-270.

[Gennady Fomkin]

I have no doubt that this will happen if the BE-4 and AR-1 engines take place, if they are brought to mind. But I doubt very much that they will be brought to mind by that time. Since the American experts "always had a bad time" with the creation of liquid rocket engines. There are no necessary technologies. What is their secret:

"The supply of high-pressure kerosene in an oxygen-enriched environment leads to instant destruction of the most stable alloys. The RD-180 engine consumes about 1 tons of fuel per second, which is supplied by a 25 kilowatt turbo pump, which exceeds the power of the reactor of the atomic icebreaker" Arctic "more than twice. That is, in one chamber with a diameter of only 180 millimeters, a little more than 000 tons of fuel per second burns, releasing gigantic energy, which modern American technologies will not be able to control for a long time." And their story with the engine on kerosene and oxygen LRE F-380, which they allegedly used when they flew to the moon.

Rocket launch on methane engine will cost $ 40,5 million against $ 45,5 million from Soyuz-2.1b.

In 2018, Rogozin reported that the government should consider the project of creating a Soyuz-5 rocket not on oxygen-kerosene, but on fundamentally new methane engine.

The Roscosmos presentation states that the preparation time for the launch of a liquefied natural gas (LNG) carrier rocket directly at the launch site of the Vostochny cosmodrome will take less than a day.

One of the slides compares the Soyuz-2.1b rocket currently in use and a promising launch vehicle. The preparation time for launch at the Soyuz-2.1b launch site is from two to five days, while the new rocket has less than a day.

By engines:
RD-0177 - they rolled off a model gas generator and will now work with a nozzle, then they will assemble a prototype. Delivery 24-25 years.
RD-0162 - conceptual design and individual field elements. Due to procrastination with money 21-22 years, the output on current indicators is 0177.

"They think" ... yeah, a journalist from RIA, according to your headline unsuccessfully hyipanul? Literally "about replacing the Russian engine" is taken from there. I even wondered why he was, the rocket was different in general. I would write that a new BE-4 engine was supplied to the plant in the USA for testing as part of the new Vulcan rocket, which is planned to replace the Atlas-5, due to the ban on the use of technologies from Russia in the USA. And everything would become clear to the people.

Who did not understand, again, the United States DID NOT DO a copy of the RD-180, they did not plan and were not going to repeat this engine, they did absolutely new engine.
RD-180 runs on kerosene and liquid oxygen
BE-4 (Blue Engine 4) methane + liquid fuel

[Grazdanin]

BE-4 is also a reusable engine.

[kpd]

They also differ in traction:
RD-180 produces 390 ton-force at sea level, and BE-4 only 245 ton-force at sea level.

[Grazdanin]

Different engines for different launch vehicles with different tasks.

[kpd]

Namely, a direct replacement of the engine will not work on the existing launch vehicle, so this is not a replacement, but an analogue.

No. Stop. What are these "different tasks"? Vulkan is officially replacing Atlas-5. For the same tasks.

[Grazdanin]

Atlas 5 and Vulcan are different rocket carriers, RD180 uses kerosene, BE-4 methane, RD-180 disposable, BE-4 reusable (up to 25 times reuse) there is nothing common in these engines.

You read inattentively. I'm not talking about hardware, I'm talking about a task. The challenge is to launch the payload. As for the RD-180, it is also reusable. It’s just that this feature is used only when burning in fire tests before being sent to the customer. The design of the Atlas-5 does not allow it to be used this way in flight.

By the way, RD-107A is also reusable.

[pytar]

They also differ in traction: RD-180 produces 390 ton-force at sea level, and BE-4 only 245 ton-force at sea level.

Here it will be appropriate to make an analogy:
For racing on F1 cars, they put motors to the extreme limit! The engine runs at maximum, and only once, for more, it has no resource. This is a type of RD-180.
On ordinary cars, put less boosted engines, but with a service life of hundreds of times higher. Therefore, they are massive and affordable! The freight price below is obtained! We do not make trains, buses, airliners disposable !!! BE-4, Merlin, Raptor, and rockets created from them, reusable, therefore more economically effective.
The advantage of reusable missiles is obvious! The concept of reusability, quite natural, it is the next logical step in the evolution of space exploration! It has become a reality, thanks to the fact that NASA has opened Cosmos to private companies, and they are looking for efficiency! Healthy competition, in which, so far, Russia is not present ....!

Quote: pytar

The engine runs at maximum, and only once, for more, it has no resource. This is a type of RD-180.

This is where they write about our reusable engine?
The RD-180 has a throttling mode. And this throttling is possible in the range of 40-100%. In other words, it's like a gas pedal, if you want to start the engine at half power, if you want - at full power. This mode is not superfluous in manned astronautics. For example, on our "unions" as the fuel depletes, the acceleration increases, and this is not buzzing. If there was a throttling engine, then you can choose a mode when it is comfortable for astronauts and more profitable in terms of fuel.
I came across the information that the BE-4 just had a throttling problem. I did not find additional information on this topic.

[pytar]

Throttle mode and reusability, different things! Such an expensive and perfect product as the RD-180 rumbles only once, and then goes into the trash, for a repeat it is not good. The BE-4 probably has some kind of childhood ailments. Correct, no doubt.

[Bad_gr]

Quote: pytar

Throttle mode and reusability, different things!

Where am I arguing with this? Throttling allows you to use the engine not at full power, one of the advantages of which is the extension of the engine life.
And reusability is, first of all, the resource of the engine, which allows you to use this engine repeatedly. The RD-180 was made on the basis of the RD-170, which was originally planned for reusable use (sides of the Energia launch vehicle) Where does the information come from that the RD-180 is one-off?

The Americans said they made a new engine to replace the RD-180. It would be interesting to know what characteristics this American miracle has. Specific impulse, pressure and temperature in the combustion chamber. In all these parameters, American engines are inferior to RD, and very inferior.
The engine running on methane + liquid oxygen from the engine on kerosene + liquid oxygen is essentially the same.
The most modern American engines lag behind the RD for generations. No wonder the United States hide the cost of their launches into space.

Accordingly, the specific impulse is larger, not by much. but more. Actually the methane + oxygen scheme takes an intermediate place between the kerosene + oxygen and hydrogen + oxygen schemes in terms of efficiency. There are many more goodies with methane. You can enlighten at your leisure.

calls for a complete abandonment of the Russian RD-180, this is unlikely to be done until 2024. The main reason is the high cost of the American analogue and the unpreparedness for its mass production.

Fact. As they say, clever enough. Petty bourgeoisie, read (if you can) not only headings.

Yes, if it weren’t for Rossiyushka, he would have rode on a trampoline, hegemosh.

If it weren’t for Russian, the military would dance and throw mega parties with Lockheed, for there is only one party with 100 million (Atlas5), but from 185-225 (Delta4 depending on configuration) or 420 (DeltaHavi) it’s completely different. And the American budget easily exports deltas .

In 2019, the US launches - 27 of them:
- 2 Antares for supplying the ISS with RD-181 engines. At the same time, the rocket is dead, now it has caught up with the Atlas at a price, with modest characteristics. NASA (the only customer) is exploring options for replacing this rocket after 22 years.
- 2 Atlases with RD-180. One launched the AEHF-5 reconnaissance satellite. The second Starliner in an unsuccessful attempt to reach the ISS.

In 2019, for example, 2 Delta4 (all for the military) flew and DeltaHavi also for the military.

In 2020, 3 Atlas-5s have already flown and the fourth is being prepared for launch. The first launched an automatic spacecraft for solar exploration, developed by ESA with the participation of NASA "Solar Orbiter", the second satellite AEHF-6, the third - the X-37B spaceplane (OTV-6).

The fourth Atlas 5 will soon be launched by the Persevere rover.

[donavi49]

And how many of these commercial launches?

A joint scientific mission with ESA (where the Americans not only displayed, but also participate in the project). Military 2 pieces. And the rover with the first Marisan helicopter-type UAV.

I just pointed out that, in general, Atlas, like Antares, did not fit into the markets, and now they live only at the expense of the state order (simplified). And he will take out the Delta. Especially for the military. There will only be happy. They and Mask rolled around the cabinets all the way, because there is nothing to settle there + lobbyism is weak.

So problems of natives Russia should not worry much.

Both ULA and Northrop Grumman Corporation acquired a finite number of engines in Russia, deciding their market or any other problems. It turned out they have to create their model of launches or not - this is the tenth matter. Russia, in turn, carried out at the expense of these companies virtually flight tests of engines for its new missiles.

Therefore, we are more likely to be interested in the flights of the carriers themselves, and not in their internal competition - the flights are working on the results of the actual operation of the engines, and the performance is excellent - all launches are successful.

[Karaul20]

Again the damaged phone. This engine went exclusively to the Atlas rocket, since the Russian Federation won the tender long ago, so it is problematic to replace it. They have their own engines for other missiles and they fly successfully.

Nevertheless, they were born only now, and even then, somehow clumsily.

In fact, they started this work as soon as they started purchasing our engines. And Katorgin explained through the media probably 20 or 30 times what, how and why. But why listen to a specialist in engines, we are "ourselves with a mustache"
Now they rolled out their BE-4. Not yet serial, but passed the EMNIP fire test cycle. But after how many years will our similar engine appear ?? They calmly, without haste, engaged in a whole set of new engines, simply buying from us those that they needed, but starting production at home was more expensive than buying from us.

But they certainly do not have a goal to overtake and overtake Russia. Therefore, their progress is moving, because they all have their own goals, just someone has more resources, someone less.
If Russia is useful for achieving the goals or they are the same, they will cooperate. If there is no benefit or cooperation is too expensive then they will not. That's all.
And what is Russia’s goal in space? What do we want in 20-30 years? Keep up with the US and China?

Interesting. It’s somehow strange that you argue "to lag behind, not to lag behind." Russia is not chasing anyone. Today Russia is preparing to deploy its radar and arctic remote sensing groups - it is restoring what was lost and creating what had never been before. As they used to say - in the interests of the "national economy".

In the short term, all these groups, including the latest satellites of the so-called. "Internet of Things" and communications will create a joint grouping "Sphere". And this is more than 600 spacecraft of various classes. Therefore, we will need launches of the heavy Angara missile (which costs three times more ) - to deploy such a large space segment. In addition, Russia must learn to maintain all of these spacecraft in working condition. But it is not enough to create a grouping in space - it is necessary to pull up the ground segment and link it with the end user, otherwise why is all this in space necessary?

As an example of the old approach to space systems, I can cite the Luch relay system - it was deployed quite a long time ago, but consumers are only connecting to it now, since subscriber terminals were not developed in time.

But "Sphere" is what is called a "pragmatic" space. Ultimately, he brings in income in one way or another. And there is also fundamental scientific research, they bring nothing but knowledge. It is within the framework of such research that the Spectrum program of large astrophysical space observatories exists in Russia and is being successfully implemented. That is why in Russia it exists and begins in practice from next year, with the launch of the AMS "Luna-25", the Lunar program. That is why, in the framework of international cooperation, we are exploring Mars and are going to conduct studies of Mercury.

As for manned cosmonautics - by 2030 at the Vostochny cosmodrome an infrastructure will be created to service TEM - the development of which is in full swing. And then the distant planets of our system will become available. All at once.

Whistle further laureate Let's start with the fact that in order to comply with US legislation, the RD-180 joint manufacturer is indeed considered to be Pratt & Whitney. Shipilov deliberately omitted the word "joint", and I underlined it.

Engine manufacturer - NPO Energomash. And "Pratt & Whitney" does not stand in any way here, since 100% of the engine is assembled in Russia and from Russian materials.

The sale of the RD-180 was carried out by a joint venture between Pratt & Whitney and NPO Energomash, called JV RD-Amros (RD-AMROSS). Sale.

Purchase and installation were made by the United Launch Alliance. This is Boeing + Lockheed. And yes, ULA has the exclusive right to install RD-180 in the USA.

As for the “transfer of all rights and all documentation,” which, according to Shipilov, make the RD-180 an American engine, which is only being assembled in Russia.

Moscow. 5'th of July. INTERFAX.RU - The mission of Pics Or It Didn't Happen to deliver seven small space satellites to orbit using an Electron rocket failed, according to the American private carrier developer Rocket Lab.

The launch of a two-stage rocket from the launch site of the Rocket Lab company on the Mahia Peninsula in New Zealand went according to plan, but there were problems in the fourth minute of the flight. As a result, no one was hurt; the launch pad was also not damaged. Currently, the causes of the emergency are being established.

The company notes that the failure was preceded by 11 successful launches in a row, and eight more Electron rockets are now in production, which allows you to quickly resume work on putting satellites into orbit.

The rocket Electron of the aerospace company Rocket Lab can bring up to 250 kg of cargo into a low reference orbit. The cost of launching a rocket ranges from 4,9 to 6,6 million dollars, which is extremely small compared to the launch of medium and heavy classes. Thus, the Rocket Lab is committed to revolutionizing the space rocket market.
