A new rocket engine has been created in Russia
“The initially lightweight Soyuz-2.1v was created on the basis of the NK-33 engine, on which the groundwork had been made since Soviet times — a certain number of engines are kept in stock. Tests of the first launch vehicle are planned on these engines, but now there is a discussion about whether or not to restore the production of these engines. In my understanding, it would not be a wise decision to restore the production of these engines, because we have created a modern analogue of this RD-193 engine, which exceeds the NK-33 technical specifications. Moreover, we have already established production of a prototype of this engine, created on the basis of the engine for the Angara RD-191, ”said V. Solntsev.
According to him, NPO Energomash has released a draft design for the modification of this engine for Soyuz-2.1в, conducted five fire tests of the prototype.
TsSKB-Progress considers this engine for the future, i.e. when the reserve of NK-33 engines will be completely exhausted. We are ready to supply the engine, ”said V.Solntsev.
The new RD-193 engine is smaller in height by 760 mm and by almost 300 kg is lighter than the RD-191.
