All deadlines for the creation of RD-171MB are fully implemented, said in an interview Merchant Head of NPO Energomash Igor Arbuzov.


In "Energomash" talked about the creation of the rocket engine RD-171МВ


According to Arbuzov, the draft engine design was developed at the end of the 2017 of the year. Today there is a release of design documentation, work is underway on the preparation of production capacity and bench base. This year, the design layout of the unit has also been created to meet the requirements adapted to the new rocket. By the end of the year, a dynamic mockup will be supplied to the RCC Progress.

Firing tests of the first RD-171MB engine are scheduled for 2019 year,
he said.

Arbuzov said that the first commercial engine is planned to be delivered to the customer in 2021 year. It is designed for the unmanned launch of the Soyuz-5, which is to be held in the 2022 year. For a manned launch, the RD-171МВ will be shipped in the 2023 year.

When asked about the possible supply of S7 Space engines (for Sea Launch), the head of the company replied that “they are going to buy”, but the contract has not been signed yet - there is still no clear understanding on how much to deliver and where. And the contract that is announced everywhere (on 12 missiles) is likely to be completed with units of the old design, he explained.

As for cooperation in this area with Chinese colleagues, they will probably be involved in the creation of methane and hydrogen engines for the upper carrier stages. At the same time, the issue of transferring technologies to the Chinese side is not worth it.

Technology transfer may be a variant of cooperation in some other areas, but “definitely not in the rocket engine building industry,” he added.

      How many brains have flowed to America, to Europe and Israel
      - the Chinese got the rest

    Yes, they don’t have to give anything to these Chinese, they will copy wassat .

      However, aircraft engines still cannot fully copy. Somewhat inferior to our prototypes in terms of performance, and significantly - in terms of resource.

        They couldn't do much.
        And we could do a lot of things.

    From Wikipedia. But I still don’t really trust her.
    RD-171MV is a Russian closed-cycle liquid propellant rocket engine with afterburning of oxidizing generator gas after a turbine, equipped with four combustion chambers and running on a pair of oxygen-kerosene. The NPO Energomash is being developed for use in the first stage of the new medium-class Soyuz-5 carrier rocket and in the first stage of the future superheavy rocket for flights into near and deep space.

    The RD-171MV engine is an upgraded version of the RD-171M engine, which differs from the prototype by a new regulation system that excludes the use of imported components, as well as a number of technological and design solutions worked out during the operation of the RD-180, RD-191 engines (for example, additional measures were applied fire protection). There will be no fundamental differences from the original engine in hydraulic and gas-dynamic parts.

    The RD-171MV will be the first Energomash engine, the original design documentation of which will not be paper drawings, but electronic 3D models. Based on electronic documentation, technological processes and control programs are drawn up for modern multi-axis machine tools with numerical control, which can significantly reduce the development time of the engine, optimize its manufacturing process and, as a result, reduce the total cost

      Excluded the use of imported components? For that, the equipment is almost 100% imported.
      3D electronic models are easier to slam wassat ... a joke of humor ...
      But it was necessary to switch to 3D-models 100500 years ago! Energy is still in paper! A couple of years and it will be as far away as the memorable Saturn-5

    That engines continue to be supplied by the United States, in exchange for sanctions.

        And what's wrong with the fact that America is unwittingly! sponsor our designs. Even funny wink America sponsors the development of rocket propulsion in Russia! And to hell where they jump, now they are in the role of catching up.

          And where do they catch up?
          If on manned systems - everything is sad: they will finish their modern ones, and we?

    The RD-171MV engine is an upgraded version of the RD-171M liquid-propellant rocket engine and is intended for use in the first stage of the promising Soyuz-5 launch vehicle. When creating it, a number of technical solutions were used that have already been applied in the RD-180 and RD-191. Some of the engine components will be manufactured using additive technologies.

          Do you deny that your picture in the post at 16:06 is not Soyuz-5? This can be seen in your own picture at 19:24. In the picture for 16:06 you have an old project with the same name from the Progress RCC. The picture shows the projected version at 19:24.

    when there will be reusable engines and when we stop carrying the staff

      Reusable engines (propulsors) will be when science invents another principle of movement in an airless space or some anti-gravity thread.
      We will stop carrying the Statesmen when they have their own best practices for ours or when they themselves refuse our services, but for now their money is for our benefit and for development.

        Roscosmos complained of sanctions and dumping prices Ilona Mask

        The competitiveness of Russian space technology in the world market has fallen due to the dumping activities of SpaceX, which is headed by entrepreneur Elon Musk. In addition, the plans of the state corporation to carry out the launches were not implemented due to sanctions and the weakening of the ruble. 

        According to the plan, the share of Russian exports of rocket and space technology should have amounted to 24,5% of the world market at the end of last year, but in reality this figure was only 8,5%.
