Roscosmos will develop a hydrogen engine for the Angara-A5V rocket

Roskosmos has decided to develop a hydrogen engine for the Angara launch vehicle. This was reported by the press service of the state corporation.


According to Roskosmos, the hydrogen engine will make it possible to develop a rocket with increased payload, and in the future - a rocket with reusable stages. Earlier, the state corporation decided to speed up work on the Angara-A5V rocket of increased payload with a hydrogen engine. At the same time, it was clarified that today such an engine, called RD-0150, exists only in the drawings.

Yes, this decision has been made

- leads RIA News statement of the state corporation.

According to available data, the hydrogen engine is planned to be used in the third stage of the Angara-A5V rocket, which will significantly increase its carrying capacity. It is planned that, with a hydrogen engine, Angara will be able to launch into low-earth orbit up to 37 tons of payload, while with a conventional engine the payload does not exceed 20 tons.

When the hydrogen engine will be created, it is not reported, but the Angara-A5V rocket itself should be presented no later than 2025. Dmitry Rogozin, CEO of Roscosmos, announced the development of a super-heavy booster rocket in April 2019.

According to Rogozin's statement, work is underway in Russia within the framework of the following projects: light-class missiles - Angara 1.1 and Angara 1.2, in the middle class - Soyuz-5, in the heavy class - the carrier rocket - Angara-A5, in the super-heavy class - "Angara-A5V". At the same time, he explained that the Angara-A3 project never existed, since there was a Zenit rocket, which was replaced by the Soyuz-5.

The Angara is a family of new-generation Russian space rockets. The first launch of the heavy "Angara" took place in the 2014 year from the Plesetsk cosmodrome.

      Meanwhile, the Chinese mission to Mars has successfully kicked off today. The Arabs left a little earlier, only Perseverance remained with a Martian helicopter-drone. We are waiting until August 11 (while the Mars launches window is open).

        Roscosmos has decided to develop a hydrogen engine for the Angara launch vehicle.
        Just a solution? And in 2017, they have already begun to develop. Are they now making the decision to start development that started three years ago?

        Development of a hydrogen engine for the Angara-A5V high-capacity launch vehicle has begun,
        https://tass.ru/kosmos/4323053

        It seems to me that somewhere in Roskosmos they have already developed a superluminal engine, because they managed to violate the principle of causality: they started development before making a decision to start it.

          You are a little wrong with the date.
          As early as August 26, 1995, a Resolution of the Government of the Russian Federation was issued. Which determined the start date of flight tests of the Angara spacecraft complex - 2005 and the concept - the launch vehicle should be two-stage with a batch arrangement of tanks with sequential operation of the stages. Oxidizing agent - liquid oxygen, fuel - kerosene at the first stage, and liquid hydrogen at the second. Assembly diagram - URM.
          Subtracting 2020 from 1995, we get 25 years. After 25 years, they only managed to START THE DEVELOPMENT of a hydrogen engine after the concept was approved. A quarter of a century later.
          Let's say a hydrogen generator will be made. But what will it do?
          After all, the layout has changed dramatically.
          When it became clear that the A5, molded according to the URM-2 scheme with a 4-chamber kerosene / oxygen engine RD-0124AP, would only pull 24,5 tons with the use of Breeze-M / DM accelerators on LEO (and this is the Proton carrying capacity), a project appears Angara-A5V. Its first 2 stages are assembled according to the URM-1 scheme, and the 3rd - URM-3V with 2 RD-0150 engines. The same hydrogen / oxygen.
          And here a nuance arises, already noticed by specialists. The fact is that hydrogen is a very expensive thing, which immediately kills the launch price. The second difficulty is that the launch needs two separate cryogenic refueling systems (oxygen / hydrogen). Plus, the KBTK booster also eats hydrogen. As a result, the launch price also rushes into space.
          But what about the price of the fraudster Musk on Falcon Heavy? Everything is in order there. Firstly, the RN Kerosene mask. Secondly, it throws almost 64 tons at LEO. To compete with it Angara - A5B, which can barely drag out 37 tons, is beyond its power already at the stage of its design.
          She will not be able to compete with New Glenn, which also surpasses her in carrying capacity. Yes, the engine of the 2nd stage there is also hydrogen, but the 1st is reusable. This automatically lowers the launch price.
          So who will need Angara-A5V (if it is still built) on the commercial international space market?
          You can, of course, mess up Musk's propulsion landing stage. But will it work? How long will it take? 10 years for project / production plus the same amount for revision based on test results?

            So it was developed in order to change the Proton. You have a problem with causation. laughing

            The rest can not even be commented on - just some kind of delirium of consciousness.

              Again. For a hurray patriot.
              1. After the Decree of the President of the Russian Federation of January 6, 1995 "On the development of the Angara KRK".
              On August 26 of the same year, a Resolution of the Government of the Russian Federation was issued, which determined the stages in the creation of the Angara complex, a general plan-schedule for the creation of the complex, the volume of its financing and cooperation were approved. The project accepted for development provided ... the use of liquid hydrogen at the second stage of the LV.
              Is the meaning of the phrase "liquid hydrogen" clear? Or write in capital letters?
              I repeat: in January 1995, they tried to create what von Braun put on Saturn-5 back in 1967.
              Now I am quoting the title of the article - Roscosmos will develop a hydrogen engine for the Angara-A5V rocket. Is the meaning of the title clear? If not, I will explain: such an engine has not yet been made. The creation of which was announced by the Government of the Russian Federation back in 1995. Now, let me remind you, it is 2020.
              2. Cheating is not good. The RD-0150 engine does not exist in nature today. According to Igor Arbuzov, head of NPO Energomash, his enterprise may come up with the creation of RD-0150 for Angara-A5V only in 2024.
              3. Angara-5 was developed really to replace the Proton. But, alas, it did not replace it. For the load is dragging the same, and the price is off scale. Therefore, the Angara-A5B project, which is being discussed, appeared. I hope you got the causal relationship?
              4. If you can not comment, why do it?

                At Proton, when it would be new, too, the price "rolls over". There will be a series, there will be a comparable price. In principle, it is now already comparable to the commercial one.

                  1. No one cares where you are looking. I repeat for the third time: the development of a hydrogen / oxygen pair engine for superheavy was announced in 1995. Now, in 2020, the government is talking about the same thing. A quarter of a century later. For RD-0150 was not, and is not. Where is the mistake in my interpretation of events?
                  2. What have the KVD-1 and RD-0124 to do with it? We made an engine for the accelerator and for the 3rd stage Soyuz-2.1b - good. But what do they have to do with the Angara-A5B?
                  3. "On July 30, 2018, the head of NPO" Engomash "Arbuzov, in an interview with the media, said that the RD-0150 is a new engine and is NOT CREATED on the basis of RD-0146", teach materiel.
                  4. The price of Russian RN will never be comparable to the prices of Mask. For a multiple launch is always cheaper than a one-time launch. And Musk is not selling rockets, but launches. Try to understand the difference between these terms.
                  5. Angara -A5B is not suitable for a lunar mission. The advice is the same - learn materiel. In this case - performance characteristics.
                  6. The question is the same - why then comment?

                    Yes, I accidentally typed in a different number. RD-0120 of course. The KVD-1 was on the 12KRB, the RD-0120 was on the Central Bank of the Energia launch vehicle. These are all hydrogen-oxygen engines.

                    Literally - "it partially uses the developments on RD-0146 and RD-0120 from the central unit of the Energia rocket." laughing And it is clear why - it is more powerful.

According to their estimates, it will be a little more expensive than the Proton.

            There are deep and well-founded doubts that an efficient energetic process of interaction of hydrogen with an oxidizing agent will be created. Painfully precise proportions must be observed in order for this to be applied as a mass ejection flight technology. And there is no such technology yet. It remains only to observe which paths will go to this

          If you don't be honest, there is no intellectual component in modern Russian space, since the USSR's developments are still being used and practically nothing "Russian" has been created so far, only solid projects go jamb, no money, since the overwhelming number of launches is paid for from - over the hillock ...

And with your "wheel" logic, why reinvent the wheel with spokes?

              After all, there are excellent wheels made of boards, they ride great.

If it is simple with oxygen, then with hydrogen, everything is many times (if not an order of magnitude) more complicated. It is clear that hydrogen as a fuel is inaccessible in terms of its calorific qualities, but still. Well, let them work, we'll see.

The stupid decision was to move the production of Proton from Moscow to Omsk, as was the stupid decision to build Vostochny in the place where it is now .. The location of the Cosmodrome near the Ocean and the plant not far from it is what had to be done, there are much more advantages to the convenient transportation of Oversized Cargo , and people are more willing to work near the ocean than in the Taiga, what kind of thread.

                There is a wide scope for creativity! :) And all because the first stage is normal, monoblock, and with a good engine. Its starting thrust is 740 tons with good specific impulse. Consequently, the starting mass of various modifications of the Soyuz-5 can be safely increased to 600 tons, and more. And for this reserve, to pile up on the second and / or subsequent stages whatever one wants, even methane, even hydrogen. Here is the means for making money geostationary. And if a heavyweight is required, to mold together three-five-seven blocks on the basis of the first stage of the Union-5, here we have full participation in the lunar-Martian wishlist. And because of the Angara all this is postponed indefinitely !!

    Only money and paper are wastedly transferred, the return is not a penny. sad

    Hydrogen and reusability? Hmm, tricky and doesn't offer many advantages over methane.
    It is clear that hydrogen is the best fuel, but it is painfully insidious, it requires exceptional adherence to technology, with which Roskosmos has not been very successful lately.
    Well, another super-heavy for what? Have you launched many Energies? Is it full of loads for it, is it required 50-100 launches per year?

      For that, there will be beautiful shots of explosions during launches - these freaks already cannot even put a rocket on the launch pad normally, carelessness, indifference and curvature at the launch sites of Roscosmos take new heights.

    On the second stage of the Energia launch vehicle, we had single-chamber rocket engines RD-0120 with a thrust of 148 tons each at the Earth's surface and 200 tons in the void, running on oxygen-hydrogen fuel (oxidizer - liquid oxygen -186 ° С, fuel - supercooled liquid hydrogen - 255 ° C).

    In order to understand that Angara is a dwelling place, you just need to mentally place three classmate missiles nearby: Proton, Falcon and Angara-5. All three have approximately the same carrying capacity. Very clear. And in order to become completely sad, they must also be imagined nearby, but in a pre-launch configuration, with all the structures located near the rocket itself at the moment of launch. Hangara - LANDSCAPE. One explosion - and tryndets the whole launch complex! The cost of restoring will be the same as building a new one. Neither Proton nor Falcon would do that much harm. And there is nothing to say about the transcendent constructive complexity and high cost of the rocket itself, some mothers ...

    instead of closing the "hangar", for the time being, use "unions" and "protons" and design a reusable methane engine and a methane spacecraft with landing steps on the runway (given that we do not have an option to land on the northern seas with storms), they are developing another ... ... Although, fortunately, it is hydrogen, and in the event of a fire, it will immediately lead to the destruction of everything in a decent radius and the closure of the program due to the lack of money to restore the infrastructure. minuses before it bangs out another five years (optimist ... probably 10 years)

    In vain they bind with hydrogen. It is effective but extremely haemorrhoid. It will be hard to operate. And dolb .. in it will be necessary to somehow close to the fuel and not let start.

    So Angara A5 is 23 tons, they plan to modernize up to 27 tons, as far as I heard, and even hydrogen, yes - 37 tons of LEO. And this is just a heavy PH. Super-heavy - this is the Yenisei under 100 tons of payload assembled from the launch vehicle Union 5

      according to plans:

      2023 - launch of the first A5 from Vostochny with 10% boosted RD-191M engines
      2024 - launch of the first A5M from Vostochny - the first modernization of the rocket - URM-1M and URM-2M
      2026 - launch of the first A5V from Vostochny - the second modernization of the rocket - the third hydrogen stage (the engine of which is said here)

      2027 - the launch of the first Yenisei from the East - assembly of a package of the first stages of the Soyuz-5,6 missiles and the third stage of the A5B.
