MOSCOW (Roscosmos PR) — General Director of the Research and Production Association Energomash named after Academician V.P. Glushko (part of the Roscosmos State Corporation) Igor Arbuzov, in an interview with the Roscosmos program Big Space, spoke about the results of the enterprise’s work in 2021.

“The entire NPO Energomash team worked well together and we managed to achieve significant success. We fulfilled our obligations to our customers and continued to develop projects for digital development, reconstruction of the test base and improvement of the technical equipment of our workshops and technologies,” he said.

He said that last year, NPO Energomash successfully conducted the first tests of the RD-171MV engine designed for the Soyuz-5 rocket, and delivered the first such engine for bench tests as part of the first stage.

Among the immediate tasks of the enterprise, Arbuzov singled out the supply of the RD-171MV engine for flight tests and the completion of the design documentation for the RD-191M engine for the Angara-A5M rocket.

According to him, the company has almost completely switched to digital design and production. Last year, engines developed and manufactured by the NPO Energomash integrated structure were used in 25 launches of Russian launch vehicles – Soyuz-2, Proton-M and Angara-A5, four launches of the American Atlas-5 rocket and two launches of the Antares rocket .

“In 2021, the formation of an integrated structure for rocket engine building was completed. The last enterprise – the Isaev Design Bureau of Chemical Engineering – was included in the integrated structure, ”said Igor Arbuzov.

Energomash is one of the leading enterprises in the Russian rocket and space industry, engaged in the development and manufacture of liquid rocket engines. Among them are the RD-191 engine for launch vehicles of the Angara family, RD-171MV for the Soyuz-5 rocket, RD-180 and RD-181 for the American Atlas V and Antares rockets.
