Touching the future. "Tsar-engine" RD-171MV and the prospects of space

Now Russian industry is working on a promising RD-171МВ liquid propellant rocket engine. The product with uniquely high characteristics is intended for launch vehicles of the future and will have to provide a qualitative breakthrough in the industry. At the same time, the 2019 year is of particular importance to the program. In the recent past, several key events took place in stories project, and new ones are expected in the coming months.




2019 year and future


Development work on the RD-171МВ engine has been carried out since 2017. The project developer is NPO Energomash. The existing propulsion system RD-171M was taken as the basis for the new product - an option for the development of the older RD-170 engine. Through the use of proven solutions and new components, it was planned to obtain another record increase in performance. High declared characteristics have already led to the emergence of the nickname "Tsar Engine".

In February 2019, the leadership of Roscosmos announced the completion of the construction of the first experimental RD-171MV. After some preparation, this product will go on fire tests. In July, NPO Energomash spoke about the assembly of three more experimental engines, and also specified the timing of the start of testing the first product. These works are scheduled for the second half of December.

At the end of August, the RD-171MV model, along with other developments, was shown at the MAKS-2019 exhibition. Then it became known that over the next two years the layout of the new engine will be tested with the first stage of the promising Soyuz-5 / Irtysh launch vehicle.

On 1 of September, information appeared about the intention of NPO Energomash to purchase steel products for use in the construction of new engines. In this case, we are talking about "the main production for picking RD-171MV. The total cost of the rental purchased is 19,5 million rubles. All this means that in the near future the program will leave the stage of construction of prototypes and move to a new stage.

At the very end of this year, NPO Energomash will launch tests of the first experimental RD-171MV. In the future, other engines will pass the test. In 2021, the manufacturer will hand over to the subcontractors the first flight set of products for mounting on the Soyuz-5 rocket. At 2022, several launches of such missiles with new propulsion systems are planned at once. Not earlier than the mid-twenties, Soyuz-5 and RD-171MV will be fully operational.

Improved design


The RD-171MV product is developed on the basis of existing engines and differs from them in a number of components and technologies, which ensures an increase in performance. Also, the new project is interesting in development methods. This is the first engine of NPO Energomash, originally created in electronic form and without the use of paper documentation.



RD-171MV is a four-chamber liquid propellant rocket engine using a kerosene-oxygen fuel pair. With its own weight 10,3 t, the product is capable of developing in the void draft 806 tf. Thermal power - 27 thousand MW. An improved turbopump unit with a capacity of 180 thousand kW was used. Thus, as the developers point out, according to certain characteristics, the new rocket engine is similar to a fairly large power plant. In addition, at the moment it is the most powerful rocket engine in the world.

From the previous products of its family, the new engine differs not only in characteristics, but also in design features. It uses modern materials and technologies. In addition, completely new elements have been introduced, such as a regulatory system borrowed from the RD-191 engine.

The RD-171MV propulsion system is proposed to be used with new launch vehicles capable of effectively using its high characteristics. Work is already underway to create new missiles of various classes specifically for the Tsar Engine.

Carrier rockets


According to current plans, two promising missiles of different classes are being developed for using the RD-171MV. The potential of the propulsion system can be used in medium and superheavy class launch vehicles. Both samples will have to go into operation no earlier than the second half of the twenties.

Since 2015, the Progress Rocket and Space Center has been developing the new Soyuz-5 medium launch vehicle, also known as the Phoenix and Irtysh. The first stage of such a rocket will be equipped with an RD-171MV installation, while the second is proposed to use other engines. The flight tests of the Irtysh are planned to begin in 2022, and in the middle of the decade it will go into operation.

The estimated starting mass of the new rocket will be 530 t, of which almost 400 t will be fuel and oxidizer for the first stage engine. Irtysh will be able to launch into low Earth orbit up to 17 tons of cargo or 2,5 tons to geostationary. Due to the high characteristics of the first-stage engine, the new launch vehicle will show certain advantages over other products of its class.



The Irtysh developments will be used in the project of the Yenisei superheavy launch vehicle, created by Energia Corporation. Several architecture options were proposed for such a rocket with common features and components. The first stage of the Yenisei is proposed to be implemented as a package of several stages of the Irtysh with RD-171MV engines. The “Tsar Engine” can also be used in a one-block second stage. The coming years are planned to be used for the design and development of the necessary products. The first flight of the Yenisei will take place tentatively in 2028.

When using the first stage with six RD-171MV engines, the Yenisei rocket will have a mass of more than 3100 t and will be able to carry a load of at least 100 t to the NOO. For GSO, the load will be 25-30 t. A rocket with these characteristics can be used to organize interplanetary missions.

Key link


Successful implementation of existing plans will allow us to continue space exploration, both in orbits and other celestial bodies. The promising Irtysh / Soyuz-5 rocket will be able to supplement and replace existing carriers delivering equipment to orbits, and there will be more serious tasks for the Yenisei. Moreover, the success of both projects directly depends on the RD-171MV engine.

Tests of the experienced Tsar Engines will begin this year and will last until 2021-22. Then, such products will be tested with the Irtysh rocket, and in a few years the first samples of the Yenisei are expected to appear. The current work, in fact, lays the foundation for further practical successes.

Thus, in the medium and long term, the Russian space industry will immediately receive several instruments of different classes suitable for solving a wide range of tasks. New carriers will provide promising research programs, as well as strengthen the position in the launch market. The key link in the current plans for the creation of new rocket and space technology is the Tsar Engine - RD-171MV, which has yet to be tested.

          Incidentally, the question is fair - not in the sense of construction, materials, ideas, etc. and in the rights to the engine. At one time, the rights to RD-180 were granted (sold?) To the Americans and formally (!) They fly on “their” engines. We bought the same rights ... So it is very curious how things are with the new line. In such an aspect.

            At one time, the rights to RD-180 were granted (sold?) To the Americans and formally (!) They fly on “their” engines.

            For starters, you would specify what was given right?
            https://ru.wikipedia.org/wiki/РД-180
            In 1996 year right to use the engine was acquired by General Dynamics.

            At the same time, despite the numerous rumors circulated in online media and blogs, patent rights to the design of the engine belong to NPO Energomash; at the end of 2018, all engine production is concentrated in Russia

              I agree, if this is true for all 100%. On the other hand, the 90s ... The Yak-141 developments "sailed away" to Lokhkid and now it turned out what happened. Therefore, there are doubts. You need to read the fine print in the contract to be sure about the absence of “bookmarks” and timed mines,

                Generally no need to read any small fonts. The Americans were given a license valid for 2020 year for the production of RD180 engines (essno with all the documentation for the production), but, apparently, it is expensive for the Americans to establish such a production, therefore they prefer to buy ready-made engines from Energomash. The design solutions used in the RD180 engines themselves are protected by patents in the Russian Federation and in the USA. According to these patents, all rights to RD180 belong to Energomash. Honestly, the bike about Americans as owners of RD180 has already been sickened. It especially delivers when they yell that once an American patent has been issued, then the Americans and the owners of the engines, and go to the website of the American Patent Office, find these patents and read English and white about Energomash’s copyright in them, apparently, there’s already not enough mind.

        I did not put a minus to you, but I will answer your question. Russian engine at 100 percent! The fact is that the basis for this engine is the legendary RD-170 (the most powerful rocket engine in the history of rocket science fellow) It was this engine that was part of the Energy-Buran side block, and half of this engine (RD-180) is sold in the USA to their Atlases. And finally, the engine quarter (RD-190) is placed on the Angara. So, the engine line is designed along and across and foreign ones do not even smell! hi

          Interestingly, the Zenit rocket (of the same type with the Phoenix / Soyuz-5 / Irtysh) was predicted to replace the Soyuz for flights with astronauts. Is the new rocket replacing the Union, or is it just adding to our missile line to replace obsolete ones?

            For manned flights - yes, for the “Federation”, but to replace the Soyuz launch vehicle it would be nice to have something smaller than the Zenith / Irtysh, there is the idea of ​​the Soyuz-7 Volga with the RD-180, very tentatively for 8-9 tons. Although it is unlikely that the Volga will be cheaper than the classic P-7.

          Will Rogozin be able to create an equally powerful single-chamber - a rhetorical question

      So, what to comment on:
      The flight tests of the Irtysh are planned to begin in 2022, and in the middle of the decade it will go into operation.

      - that is, given the usual + 2 years (and this is very divine and actually world practice, see Arian, Volcano or Glen) 24-26 years are flying.

      - The first flight of the Yenisei will take place tentatively in 2028.

      Domestic SLS will fly this year in 30 +.

      Plus, again, the engine is not very innovative, in fact it’s actually a transfer to a new design structure, as well as modernization taking into account the new capabilities of the machine park (and, as far as I know, the percentage of parts printed on an 3 printer is less than 0,5% - that is, all conservatively, we are driving overweight) of the old engine, which we managed to make back in the USSR, at the last jerk. Hence the classic fuel - kerosene + oxidizer.

      In the world now everyone is carried away by methanks. The new main engine for the USA is the VE4 on methane. Musk - a new generation - on a matan. The Chinese for the new LongMarsh - make the methane engine for the 24 year.

      Also, the engine is disposable, its salvation is not provided. That is, the price tag flies into space. Which is also contrary to current trends, which even the Chinese have already learned and are developing.

          I kind of didn’t write about Mask at all.

          I just indicated:
          the news is about nothing so far - not even fire tests.
          the engine is not new, but also Soviet, just slightly updated; there are not many innovations there.
          even the Chinese are actively climbing into methane + oxygen - there is no answer to this yet. If the topic shoots, there will be a big lag immediately.

            As far as I know, they also work with a methane engine. Perhaps they are trying to adapt RD-170 \ 171, 180, 190 to CH4 ... There is little information so far.

          Upgrade, with virtually no change in the main parameters - traction and specific impulse.
          The main direction of modernization is improving the reliability with which RD-170 and RD-171 had questions.

          What blatant illiteracy of this Lopota is to blame methane for fire and explosion hazard !!

          Methane is the safest gas - it is included in the 4 hazard category.
          kerosene in the 2 category. (much more dangerous than methane)
          hydrogen in the 1 category (insanely dangerous than methane)

          Lopota turned into an illiterate bureaucrat.
          Especially funny was the sulfur sputtering - it’s easier to clean and prepare gas for operating the pH in order than heavy hydrocarbons such as kerosene.

          advantages of methane (offhand):
          1-wi (at least a little higher)
          2 engine coolant
          3 - no temperature isolation with liquid oxygen is needed (in tanks, highways, etc.)
          4- low fuel availability (no specialProduct needed, like rocket kerosene, for example)

          5-fire-explosion-safety is better than any other type of fuel (especially outdoors in open areas)
          6-lack of soot education
          7-gaseous entry into the combustion chamber (less problem with harmful sound frequencies)
          8 environmental friendliness absolute
          9-there is no need for cryoprotection for the lower stages (long-lived overclocking units may be needed)

          10-simplicity reliability cheapness of an open circuit with characteristics no worse than kerosene complex expensive kerosene closed circuit.
          Ideal for the first step. (You can increase the number of steps without compromising reliability and cost).
          11- refueling in zero gravity;
          12 - restart the engine in vacuum.
          13-ease of implementation of any schemes LRE
          14- the possibility of deep throttling due to the cold resource * 2

            top down:
            1-wi (at least a little higher)

            Yes a little
            2 engine coolant

            what kind of engine characteristic is this? the first time I've heard
            3 - no temperature isolation with liquid oxygen is needed (in tanks, highways, etc.)

            you need it anyway, otherwise oxygen will heat up, which is bad, methane will cool down, which is also bad
            4- low fuel availability (no specialProduct needed, like rocket kerosene, for example)

            kerosene is also cheap and affordable, does not require the installation of liquefaction, and high purification (special product) for methane is also required.
            5-fire-explosion-safety is better than any other type of fuel (especially outdoors in open areas)

            yeah, explosions of buildings from the GHG leak speak of its "safety". Now imagine a leak in the rocket body. Slam so that CAC may just not have time to work
            6-lack of soot education

            again with appropriate cleaning. Aviation kerosene also forms little soot. And in case of repeated use of the engine, it can simply be washed.
            7-gaseous entry into the combustion chamber (less problem with harmful sound frequencies)
            I don’t know about frequencies, but different intake schemes are considered: both liquid and gas-droplet mixture. If aerated before entering - the pressure in such a line should be wild at the desired fuel consumption.
            8 environmental friendliness absolute

            with an excess of oxygen and kerosene no worse. And only hydrogen is absolute.
            9-there is no need for cryoprotection for the lower stages (long-lived overclocking units may be needed)

            maybe for the upper steps?
            10-simplicity reliability cheapness of an open circuit with characteristics no worse than kerosene complex expensive kerosene closed circuit.

            open is always cheaper / more reliable. And in the case of kerosene, too. Nevertheless, they make it closed.
            11- refueling in zero gravity;

            is kerosene fundamentally unsuitable?
            12 - restart the engine in vacuum.

            what prevents run kerosene
            13-ease of implementation of any schemes LRE

            But this is the most important thing. If so, everything is “chocolate” with methane, then why doesn't everything still fly on methane? Ali was all so stupid, and then suddenly wiser and grabbed his head?

        the proportion of parts printed on an 3 printer is less than 0,5% - that is, everything is conservative, we are carrying excess weight

        rather, on the contrary, the excess weight of 3-D printer parts. The milled piece of iron is always stronger, and 3Desh parts still do not know how they will behave at maximum loads, so they are obviously made thicker.
        Kerosene engine can also be used repeatedly, another thing is that carriers do not provide (for now) to save. In addition, methane is less dense. Time will tell which is better. But methane as a technology is more promising, of course.
        In fact, we are "finishing" the Soviet backlog. Expensive and VERY slow. So I just didn’t understand from the article - load capacity of more than 100 was previously promised at 4 blocks of the first stage, and now at 6. On the 6-8, the “Volcano” was supposed to fly with a payload of 200 tons. At least there on the central 4 pcs. RD-0120, but this is 900 versus 800 for RD-171. Not a big difference.

          Well, that's why everyone prints details on 3 printers all of a sudden. I could give different examples, but I will give the Military Acceptance as an example (because it’s much more patriotic) with a plot about the advanced Su-57. They sang a whole ode about 3 printers and even showed vivid examples. On the left is a detail made in a classic way and quite heavy. To the right of the 3 printer, it is significantly lighter and has completely similar strength and fatigue characteristics. It is the details as the right one that goes to Su-57 now.


          Well, so I wrote. Methane is the future. If it fires, there will be an even greater lag. The Chinese are afraid to miss the train and are now investing a lot of resources in the methane engine. BE-4 is already on the final tweak. The first in the world with full gasification of elements methane engine Raptor - already flies at the stand.

        ... Hence the classic fuel - kerosene + oxidizer.

        In the world now everyone is carried away by methanks. The new main engine for the USA is the VE4 on methane. Musk - a new generation - on a matan. The Chinese for the new LongMarsh - make the methane engine for the 24 year.

        Also, the engine is disposable, its salvation is not provided. That is, the price tag flies into space. Which is also contrary to current trends, which even the Chinese have already learned and are developing.


        Actually, the RD-171 is certified for 10 flights, it is possible that the RD-171MB too. But on methane, the correct remark. In Russia, at least pour this fuel.

    Now Russian industry is working on a promising RD-171МВ liquid propellant rocket engine.

    Recently, authors on Military Review have been distinguished by very superficial judgments.
    This engine was created by 30 years ago and still has 4 units in stock. from the first series.
    Currently, the second series is being resumed, due to a significant change in technology and the use of CNC equipment, a translation of the product documentation into numbers was required. Along the way, operating time from the RD-191M engine is used. And the fact that the manufacturer is promoting as a completely new product. so it’s just cut the dough.

    Website IN! Conduct literacy courses for your authors so that they, in their propaganda frenzy and writing articles, at least do not create obvious blunders about anything.
    The “RD-171MV Advanced Liquid-Propellant Rocket Engine” is the Soviet RD-170, the work on which began in the year 1976. There are no fundamental differences between RD-170 and RD 171MV, and after 43 years after the start of development, the brainchild of the USSR is still “promising”.
    This is the first engine of NPO Energomash, originally created in electronic form and without the use of paper documentation.
    You can only blow into panfares about this because of ignorance, since the first CAD systems for designing “without the use of paper documentation” appeared more than seventy years ago, and the first AutoCAD was published in 1982.

    Where do you get such grass ?? And what were these “first CAD” systems called until the 1948 release, on what hardware did they work, were able to build full-fledged 3D models with visualization, strength calculations by the CE method, probably?
    The engine is normal, an increase in performance is possible due to a slight increase in pressure and an improvement in the quality of the mixture, for which the feed was increased. If you replace half of the parts there, you will get a new engine with all the consequences. And there are so many of them (resulting) that even the Mask with Bezos cannot be mastered for 5 years.
    Methane has already been tested on test engines, data has been collected for designing large ones (see KBHA website). The fact that there is no system to save at least the first-stage engine is a big jamb, yes .. Although it was provided for (but not tested) in the side blocks of the Energy.

    RD171 is the most powerful LRE in the absolute and the most powerful four-chamber. Maybe the author meant it? Although the pathos is busting as always; ((. I was also not happy with our throwing on promising carriers, but the choice in favor of this engine is the only possible. Adherents of methane conversion are poorly aware of the amount of work on this topic, as well as the development of an engine with Throughout the world, R&D cycles unscrupulously lengthened even for simple products, and even more so for RDs.Compare the rates during the time of Korolev and von Braun and the current ones, and this, taking into account the accumulated knowledge and competencies, the machine tool park and the wonderful CAD system.

    They ruined the Sea Launch project and the cool Zenit 3SL rocket there and stood the 171 RD and it displayed more than 4t, Medium rocket on the GSO, and the characteristics are the same as those of the Proton from Baikonur. And now they are fighting the very same horseradish with worse parameters, when someone already tricks these bureaucrats from Roscosmos, some thieves and bouncers didn’t invent anything at all, but Paphos is enough for Jupiter there.

      Rockets of the Zenit family were developed by Yuzhnoye Design Bureau, Ukraine, and they own the rights to this rocket. Now ours are creating their own with similar parameters, but at a more modern level. What's bad about it ?
      Moreover, having such engines and not using them is blasphemy.

        At 90% it was the Russian Design Bureau Yuzhnoye doing only the first step on which the Russian engine stood the very 4-x liquid chamber rocket RD-170 with 800t thrust. From Baikonur, she launched 13.5t from the Sea Launch. As many as 15 tons at the IEO there was already a finished rocket, nothing needed to be done. And the launch pad is generally unique - there was not a single person in preparation for the launch, all processes were automated. And the point here is not in Ukraine at all, Sea Launch really interfered with Proton’s business. all orders went to him. Read the interview with the ex-head of the RKK V.A. Lopot he tells in detail to whom these people prevented the Zenit rocket and are now sitting in Roskosmos!

    All this is good. Dvigalovo missile base. But that's not their new ones. Neither the "Angara" nor the Union-5.
    And, unfortunately, the Tsar Cannon does not shoot, the Tsar Bell does not ring, the Tsar Cannot bomb .....
    In general, I consider the principle of putting one powerful engine instead of a bunch of weak people to be correct. Yes, and 2 steps instead of 3 step forward.
    But I get the impression that the modern space program of the Russian Federation cannot complete its projects.
    The same “Angara” was launched 2 times and silence. And such a beautiful line of carriers turned out.

    Well, 806 in the void RD-170 / 171 has developed before. It is more interesting that he has a thrust near the ground, earlier on the Wiki they wrote 780 hardware (against the basic 740), then they removed this figure. The same 780 appeared several years ago in the booklet Energomash http://www.k204.ru/books/vrd/wiki2/PDF/Emash.pdf

    Have something to launch with new media? Not in terms of getting rid of dough on commercial launches, but in terms of a shared vision of where to move in space exploration.

    In the words of S.P. Korolev: "Space is not conquering at the stands." I would like to say to our space agency: “We’d fly somewhere!” And then we will remain with the thought that the first cosmonaut of the Earth was born near the city of Smolensk, which was then in the RSFSR - one of the 15 republics of the USSR, and now in the Russian Federation. (Note: True, I heard that the “Baltic tigers” and the Polish zucchini “13 chairs” began to shout at him.
