The developer of Angara compared kerosene RD-180 and methane Raptor


The USA and Russia entered an era of scientific and technical competitions "regarding creation of the most effective engines from the engineering point of view, the most intense", the CEO of the Kosmokurs company Pavel Pushkin told RIA Novosti. According to him, earlier Russia in the field of liquid rocket engines "was the categorical leader". Commenting on the statement of the head of the SpaceX company Elon Musk for superiority of pressure level in the combustion chamber of the power Raptor unit over the Russian RD-180, the expert who was earlier taking part in development of rockets of the Angara family noted that now early to speak about progress of the American enterprise. "For the methane engine softer temperature parameters are implemented with the same pressure that in oxygen-kerosene RD-180. Temperature in the methane engine will be lower, thermal loads are softer. Even if would make the kerosene engine with such pressure, it is a question of technical implementation: who is better-is worse. But it seems to me that key parameter is the price of the engine and a rocket. If Musk realized at low price - it is one if on high — another. If there high pressure, then it can be unreliable, and engines at a full cycle of tests will begin to fail. So far information is not enough" — Pushkin told. According to the creator of the RD-180 engine Boris Katorgin, the data on test submitted by Musk for comparison of the Russian power unit and Raptor are not enough. "Data for assessment of this statement are not enough. For a start it is necessary to answer questions: in what camera the draft, what regularity at the camera as far as process of burning is steady was received" — the statement of the designer gives TASS. Materials on teme00:01 — on July 9, 2018 Energokhlamrossiya spends billions for rocket engines. They became outdated and not нужныВ February Musk said to nobody that Raptor broke RD-180 record on pressure in the combustion chamber. In June, 2018 the CEO of Energomash Igor Arbuzov said that rocket engines on methane are more perspective than power units on kerosene and the USA advances Russia in creation of such installations. In April of the same year the head of scientific and technical council of Roskosmos Yury Koptev noted that Russia only of spacefaring nations does not use hydrogen as fuel in rocket engines.
