Answer to Musk: Roskosmos called incorrect the statement of the head of SpaceX for the RD-180 engine


Earlier Elon Musk said that the Raptor engine for the interplanetary Starship ship surpassed RD-180 in pressure level in the combustion chamber Elon Musk. Photo: Aly Song/Reuters Comparison of the Russian rocket RD-180 engine with the Raptor engine of the SpaceX company is similar to comparison of diesel and petrol units. Words of the chief designer of Energomash Pyotr Levochkin are cited on the website of Roskosmos. According to him, the RD-180 engine for the carrier rocket Atlas uses the fuel scheme "oxygen — kerosene", and Raptor works at the scheme "gas — gas" therefore in records of SpaceX "there is nothing outstanding". Levochkin added that RD-180 was certified with a 10 percent stock, that is pressure in its combustion chamber can be higher than 280 atmospheres. Earlier the founder and the head of the SpaceX company Elon Musk reported that the Raptor engine developed by his company broke the record of the Russian analog of RD-180 on pressure level indicator in the combustion chamber. Advantage in rocket production all the same remains for Musk, the research supervisor of Institute of space policy Ivan Moiseyev says: Ivan Moiseyev the research supervisor of Institute of space policy "If to take any things and to compare only on one characteristic, then it will not always be the correct comparison. Without gas it cannot work in any way, it can work only on the stand during tests. All engines work when they on a rocket, they always work with liquid. It is possible to compare, of course, in different parameters, but these are engines of one class. The fact that there pressure is slightly more practically means nothing, it is the choice of the designer. You increase pressure, but you worsen other characteristics. There are no new breaks there. Break it is possible to call that the SpaceX company reached the level of the most effective engine of this kind as we represent it now". Roskosmos said that welcome the competition in the field of rocket engine-building and called the level of developments SpaceX "rather high". To add BFM.ru to your sources of news?
