“Humanity can become a species living on several planets if we can reduce the cost of sending a ton of thrust into orbit,” said the director of SpaceX and Tesla.
In this regard, Musk mentioned the influence of Russian rocket engine designs on the development of liquid oxygen and methane Raptor engines. Recognizing that Russian engineers have created hundreds of engine designs, the billionaire emphasized that the design part is still not the most difficult.
“I spend a lot of time studying Russian rocket engine design. There are some great designs for Russian engines. They’ve been producing liquid-propellant rocket engines for a long time and They have literally created hundreds of different designsSpaceX founder said.
In this regard, Musk believes that, compared to what Russian engineers have already done, the Raptor engine has not been significantly improved.
“Our engine is more compact than before and has a complete gasification of the combustion components. But these are relatively small improvements from what the Russians have already achieved,” said the businessman.
In conclusion, the billionaire once again insisted on the importance of reducing the cost of production of the engine, adding that his goal is to reduce this amount for the Raptor to 1000 dollars per ton of payment.
