"Roskosmos" will produce two dozen "king-engines" RD-171MV

9

Two dozen of the most powerful RD-171MV, which has already been nicknamed the "Tsar-engine", plans to produce "Roskosmos" until 2027. The units are intended to be installed on the Soyuz-5 medium launch vehicle and the Yenisei superheavy. This was reported on the eve by representatives of the press service of the state corporation.

Recall that in 2019, Roscosmos published a video in which the RD-171MV is called the most powerful engine in the world. However, in fairness, it is worth clarifying that it is among liquid aggregates.



At the moment, an agreement has already been signed with Perm Proton-PM for the production of steel and titanium castings for the future Tsar Engine. According to the head of the enterprise Dmitry Schenyatsky, this contract will allow the plant to proceed to development Technology manufacture of experimental products and significantly expand participation in the cooperation on the creation of liquid power units.

It is worth noting that the promising “king engine” was not developed from scratch. RD-171MV is a modernized version of the Soviet RD-170, which was created for the superheavy rocket "Energy". The unit operates on naphthyl and liquid oxygen and will be installed on the first stage of the Soyuz-5 rocket. Flight tests of the average LV are scheduled for 2022. In turn, the first steps of the aforementioned carrier are planned to be used as side boosters for the superheavy Yenisei, the first launch of which is due to take place in 2027.

    Since the "tsar" - it means that the media want to throw.
    The Tsar Cannon cannot fire, the Tsar Bell has been broken for a long time, the Tsar Tank immediately got stuck in a swamp, the Tsar plane didn’t take off (it seems), the Tsar bomb wasn’t tested with a full charge, the recently promised Tsar rocket do not promise ...... and so you can continue.

      Ummm .. "Tsar Cannon" fired, only not with the cannonballs that lie nearby, but with the so-called "stone shot". The bell was not supposed to ring, it was cast by order of the Empress Anna Ioannovna in 1730 in memory of the descendants of her reign. This is a monument. "Tsar Tank" too ... um ... was named by journalists already in the USSR. And so this is "Lebedenko's wheeled combat vehicle". Well, something like that and so on.

        Thanks for the information. Did not know. But this RD-171MV engine is truly a masterpiece. Probably, a variant of chemical engines already close to the efficiency limit. Of course, I would like to see the start of Union 5. On the other hand, according to the calculations of our "partners", by 2011 everything should have ended by itself ... However, they were wrong.

        That's it. Everyone calls the media, but it doesn’t work. Or bad.

        The Tsar Cannon cannot shoot shots. She has a pilot hole, specialists lit, deaf (did not finish), etc.

        The bell was not supposed to ring.

        - and the engine will not have to fly - the logic is iron.

      If you want, you can laugh, of course. But the RD-180 was made based on the engine of the lunar rocket N-1. And it works, the Americans do not complain.
      Energy flew realistically, so there is no reason to doubt that the RD-171MV will work.
      And what happens to the new Roscosmos ships is becoming more and more not like incompetence, but betrayal.

        RD-180 was not called the Tsar Engine. I don’t remember.

        A kind of Super-heavy Angara was called a king-rocket ...
        And then everything was blown away ....

        Shooting for such names in the media is necessary.
