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.

            You probably have a mirror behind you. We all were proud of the Soviet Union. Both flew into space, and mastered Antarctica. What are you proud of now? The retirement age raised their zeal. Amer treasury bought happiness again. Rogozin made trampolines screaming. The Minister of Foreign Affairs, except for the mat, did nothing for you again in Russia.

Well, if you launch a satellite with a NORMAL camera around the Moon, which for some mysterious reason no one has yet done, most of the questions will instantly disappear. Here it is right away. But we are not interested, right? Just think of the moon! Nobody wants to know anything about her ...

The most powerful single-chamber still remains the F-1, and it was he who sent the heaviest and most powerful Saturn-5 rocket to Space and to the Moon. The first Saturn-5 with F-1 started in November 1967, and in the USSR began work on the RD-170 in 1976.

            It’s still here, it’s in the museum, because in the first place it is hydrogen, which, in general, will do for a flight to the moon in the 70s, and now it’s too much to launch satellites and cargoes to the ISS. Even Russia is now switching to environmentally friendly "kerosene" missiles.

                Indeed, the second stage was hydrogen
                The first stage worked for 2,5 minutes and accelerated the spacecraft to a speed of 2,68 km / s (in an inertial reference frame) [15]. The second stage, S-II, used five J-2 oxygen-hydrogen engines with a total thrust of 5115 kN.

          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.

            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 Soyuz-6 and Yenisei carriers that use the RD-180MV engine in their composition.

                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 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.

            What is an RD-180 engine? This is the half (2 combustion chambers instead of 4) of the RD-170 (RD-171) engine, which we stood on the sides of the Energy, on the Zenit rocket launcher (RD-171) and will be on the Soyuz- 5 "(aka Irtysh). 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 that is unlikely: the NK-33 engines in the warehouse have been lying for decades, and still correspond to the advanced engines, I’m sure the same can be said about the RD-180 (not today, so tomorrow it will find its client)

      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 "father", the RD-170 was not used in the Union at all after the inglorious demise of the initially failed Energy-Buran project. For there was no carrier for it. And now, no. And never will. Never.
      The United States agreed to take the half-cut “dad”. In Russia, it also could not be used for the simple reason that there was no and no carrier under it. So Energomash should bow to the States belt for the fact that at least someone takes its goods, because in Russia, the RD-180 is impossible to adapt to something worthwhile (fantasies about Soyuz-6 are from the field of fairy tales by 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 another generation.
      And the SpaceX Raptor Mask 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 should forget about the 84 launches of the Zenit rocket together, right? lol RD-170 is the engine of the Energia launch vehicle parablock, RD-171 is its modification for Zenit-2, and RD-171M is a modification for SL.

                So there you have a specific answer.

                In Russia, two carriers are now in operation. Soyuz-2 of various modifications and Proton-M of the third and fourth phases of modernization, which are being prepared to replace the launch of the Angara series missiles. 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.

        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.

    Academician, general director of NPO Energomash, Boris Katorgin, wrote that the States spent 4 years to develop and launch the RD-180, but could not create this production 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 responded to the call: SpaceX, Orbital ATK, Sierra Nevada and Boeing. As well as the company: Blue Origin, in 2011 it began work on the BE-4 reusable engine (249 tf thrust, methane / oxygen fuel, two BE-4s will be installed on the rocket), and Aerojet Rocketdyne has been creating AR- since 2010 1 (thrust 226 tf, kerosene / oxygen fuel, two AR-1s will be installed on the rocket). Until 2013, Rocketdine was a division of Pratt & Whitney. It was Rocketdine that developed the RS-25 rocket engine for the Shuttle program, in principle it can be considered a replacement for the RD-180 engine, but its cost alone is $ 65 million and hydrogen / oxygen fuel, which does not allow the use of RS-25 for Atlas rocket launches, moreover, it is very complex and explosive. In principle, it has long been outdated. hi

      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.

      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).

    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.

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

    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 the instantaneous destruction of the most stable alloys. The RD-180 engine consumes about 1, 25 tons of fuel per second, which is supplied by a 180 kilowatt turbo pump, which exceeds the capacity of the Arctic icebreaker reactor" Arctic "more than twice. That is, in a single chamber with a diameter of just 000 millimeters, a little more than 380 tons of fuel per second burns out, releasing gigantic energy that modern American technologies will not be able to curb for a long time." And their story is with the engine on kerosene and oxygen F-0,6 LRE, which they allegedly used when flying to the moon. laughing

      One of the slides compares the Soyuz-2.1b rocket currently in use and a promising medium. The time to prepare for launch at the launch complex at Soyuz-2.1b is from two to five days, while the new missile 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.

I was even surprised at what it was, a rocket then another in general. I would write - in the USA, a new BE-4 engine was delivered to the plant for testing as part of the new Vulcan rocket, which is planned to replace the Atlas-5, due to the ban on using technologies from Russia in the USA. And all the people would have become clear.

                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. laughing

          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 ....! good

            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, you want to run at full power. This mode is not superfluous in manned astronautics. For example, in our “unions”, as fuel is generated, acceleration increases, and this is not buzzing. If you had a throttle engine, you can choose a mode where it is comfortable for the astronauts and the fuel is more profitable.
            I came across the information that the BE-4 just had a throttling problem. I did not find additional information on this topic.

                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 primarily a resource of the engine, which allows you to use this engine repeatedly. RD-180 was made on the basis of RD-170, which was originally planned for reusable use (Energy carrier rocket sides). Where does the information come from that the RD-180 is one-time?

    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.

      What are you saying))) Do you agree that hydrogen + oxygen is no different from kerosene + oxygen))) Is it nothing that the proportion of hydrogen in methane is greater? 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.

And the American budget easily exports deltas wink .

      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.

            Both ULA and Northrop Grumman Corporation acquired a finite number of engines in Russia, deciding their market or any other problems.

Russia, in turn, carried out at the expense of these companies virtually flight tests of engines for its new missiles. laughing

            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.

        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 groupings - restoring what has been lost and creating what has never happened before. As previously said, in the interests of the "national economy".

        In the short term, all these groups, including the latest satellites of the so-called The “Internet of things” and communications will create the united “Sphere” grouping. And this is more than 600 spacecraft of various classes. Therefore, we will need launches of the Angara heavy rocket (which costs "three times more expensive" tongue ) - 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 has been deployed for a long time, but consumers are connecting to it only now, because they have not developed subscriber terminals in time.

        But the "Sphere" is what is called the "pragmatic" cosmos. In the end, he generates income anyway. And there is fundamental scientific research, they bring nothing but knowledge. It is in the framework of such research that the Spectrum program of large astrophysical space observatories exists and is being successfully implemented in Russia. That is why in Russia there is and begins in practice from next year, the launch of the Luna-25 AMS, the Lunar program. That is why, as part of international cooperation, we are exploring Mars and are going to conduct research on Mercury.

        As for the manned space program - by 2030 the infrastructure for servicing TEM will be created at the Vostochny Cosmodrome - the development of which is in full swing. And then the distant planets of our system will become available. That's all at once.

          In the short term, all these groups, including the latest satellites of the so-called The “Internet of things” and communications will create the united “Sphere” grouping. And this is more than 600 spacecraft of various classes. Therefore, we will need launches of the Angara heavy rocket (which costs "three times more expensive" tongue ) - 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 has been deployed for a long time, but consumers are connecting to it only now, because they have not developed subscriber terminals in time.

    The program to create a domestic methane engine of the required thrust for a promising carrier in the current PCF is planned for the year 2023. More than half of the steps have already been completed. An intermediate engine RD-0162D2A was created and its AIS was carried out. We started production of RD-0177, which is the prototype of the final flight product - the RD-0169 engine. The RD-0169 engine in two versions is planned for installation on Soyuz-LNG LV.

    Thanks for the info, comrade

    So what? An oxidizing gas generator was added to the Raptor.

      And where am I disgraced? The Raptor does not have an oxidizing gas generator or can it be in the RS-25? Instead of fucking about fantasies on the topic, they would write.

        Obviously where. Where you have a Raptor reincarnation of RS25. Thus, you showed absolute ignorance of the topic, with an irrepressible desire to philosophize in it.
        And this is of course your right, but other users can read you, as far from the topic as you, and who can take your nonsense at face value. Is that bad.

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

    You just do not bother everything in a heap.
    RD-180 is a two-chamber engine, and if absolutely in a good way, these are two engines in one package.
    BE 4 - single chamber engine. And on the Volcano there will be 2 of them.

      One engine with two combustion chambers.
      About two engines in one harness is just a representation of Dmitry Borisovich Zotiev who is a mathematician.
      For a correct comparison with the RD-180, you need to divide the latter in half. In essence, it is a pair of engines in one "harness". The most critical and technologically complex unit in the LRE is a combustion chamber + nozzle.

    Not tired of you still carrying this nonsense?
    . RD-180 was created in the mid-1990s on the basis of the RD-170 liquid propellant rocket engine [1] under the direction of Boris Ivanovich Katorgin. In 1996, the RD-180 project won the competition for the creation and sale of Atlas-3 US rocket engines and Atlas 5 [3].

    Whistle further laureate laughingTo begin with, the co-manufacturer RD-180 is indeed considered “Pratt & Whitney” to comply with US law. Shipilov deliberately missed the word "joint", and I emphasized it.

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

    The sale of RD-180 was carried out by the joint venture Pratt & Whitney and NPO Energomash, called the RD-Amros Joint Venture (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.

    We figured out the rights: RD-180 is an export version that was created for Atlas and can only be operated on it with the participation of the UL alliance. The article on Military Review was laughing October 24 2017

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

    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.
