Russia has created the most powerful rocket engine

6

In the bowels of the research and production association Energomash (part of the state corporation Roscosmos), a liquid-propellant rocket engine RD-171MV was created, the thrust of which reaches 800 tons. It is the most powerful rocket engine in the world. equipment.


For comparison, the latest Raptor VI engine, designed for the massive Starship rocket, has only 269 tons of thrust.

Roscosmos reported that it will be installed on a promising two-stage Soyuz-5 launch vehicle. Also this year, they plan to complete work on the assembly of the RD-171MV for the second and third Soyuz-5 rockets.

It will launch from the Baikonur Cosmodrome, which Russia shares with Kazakhstan. Previously, Ukrainian Zenith rockets equipped with RD-171M engines were launched from this facility. It is expected that Soyuz-5 will launch a cargo weighing about 17 tons into a reference orbit.

Work on the engine began in 2017. Three years later, fire tests were successfully passed - to date, about two dozen of them have been produced. The relevant design and technical documentation has also been created. After assembling prototypes and various tests, Energomash began production.

The power of the RD-171MV is 246 thousand horsepower. A completely Russian engine, which does not have Ukrainian and other parts, is equipped with fire protection and an updated control system.

    I wonder what his fuel consumption is? Probably more than the Bugatti. In general, well done.

    Work on Soyuz-5 and its units was 20 years late, during which no one was interested in it, this very someone did not exist. The same red tape with engines of new concepts: methane and hydrogen, new carriers. Those who are interested have no money, and those who have it have no desire to share it. Musk, like the Queen in his time, does not have to beg for funding.

    It's strange - Starship with an engine with a thrust of 269 tons plans to launch 250 tons of payload into orbit, and Soyuz 5 with an engine with a thrust of 800 tons - only 17 .. some kind of garbage. With such thrust, it should have a payload under 500 tons ... someone is lying.

      Starship has 20 engines.

    This is the engine of the last century. It has four chambers, and creating a chamber for 200 tons is not a problem. Here is a single-chamber F-1 Saturn-5 had a thrust of 790 tons, they managed to solve the problem of uneven combustion in a large volume chamber. Then the power of the engines was important, because. the smaller the engines, the easier they are to manage. But now powerful engines are not in demand in rocket science, because. the concept of reusability is not feasible with them. The fact is that the first stage of a rocket weighing tens of tons can be returned to the ground only by vertical landing. The first stage of the Proton weighs 30 tons + 10 tons of fuel = 40 tons. To lower 40 tons to the surface of the Earth, it is necessary to reduce the thrust to 40 tons, otherwise the rocket will not land. And to reduce the thrust of the rocket engine from 800 to 40 tons, i.e. 20 times impossible. If we have 4 engines of 200 tons each, then turning off 3 and reducing thrust by
    the latter by 5 times, which is technically possible, we will just get 40 tons of thrust.
