The United States and Russia entered into an era of scientific-technical competition “to create the most effective from the engineering point of view engines, the most intense,” said RIA Novosti the General Director of company “Kosmocar” Pavel Pushkin.

According to him, earlier Russia in the field of liquid rocket engines “was the categorical leader”.

Commenting on the statement by the head of the company SpaceX Elon musk about the superiority of the level of pressure in the combustion chamber of the power unit Raptor over the Russian RD-180, expert, previously participated in the development of rockets of family “Angara”, said that at present early to speak about the success of American businesses.

“Methane engine being implemented in more mild temperature parameters at the same pressure in the oxygen-kerosene RD-180. The temperature in the methane engine is lower, gentler heat load. Even if I did kerosene engine with such pressure, it is a question of technical implementation: who is better-is worse. But it seems to me that the main parameter is the price of the engine and missiles. If Musk is sold at a low price, this is one if high is another. If there is high pressure, it can be unreliable, and engines with the full cycle of testing will begin to shut down. While information is not enough” — said Pushkin.

According to the Creator of the RD-180 engine Katorgina Boris, test data submitted by the Mask, for comparison, the Russian power unit and the Raptor, is not enough. “Data to assess this statement, very little. First you need to answer the questions: which cell were obtained traction, which measured the camera, how the combustion process is stable,” — TASS quotes the statement of the designer.

In February, Musk said that the Raptor broke the record of RD-180 on the pressure in the combustion chamber.

In June 2018, General Director of “Energomash” Igor Arbuzov said that rocket engines using methane promising powertrain on kerosene and the United States ahead of Russia in the creation of such systems.

In April of the same year, the head scientific-technical Council of Roscosmos Yuri Koptev said that Russia is the only space-faring nation does not use hydrogen as a fuel in rocket engines.
