NPO Energomash (part of Roscosmos State Corp) has successfully completed fire tests of the RD-171MV developing engine designed for the perspective Soyuz-5 space vehicle.

The developing rocket engine is now in its final design version; tests confirm the compliance of the engine characteristics with the requirements of the technical specifications.

In the frames of the test program, the most powerful liquid rocket engine in the world (its thrust is 800 tons) worked for a total of 1461 seconds in nine firing tests without being removed from the test facility.

All tests have passed successfully and confirmed the characteristics laid down in the design of the engine.

Yuri Borisov, Head of Roscosmos State Corp: “The quality and reliability of the products of the Russian rocket engine industry leader has once again been confirmed by successful tests and launches with LRE which are developed and manufactured by NPO Energomash. The enterprise retains key competencies that have been created over decades - a strong design school, engine development and prototype production as well as production of powerful reliable engines.”

Igor Arbuzov, Director General of NPO Energomash: “Completed fire tests in different engine operating modes were actually “life tests” of the entire machine, including upgraded units and assemblies, engine control systems and emergency protection. NPO Energomash meets the deadlines for the development and testing of the engine running on an environmentally friendly naphthyl-oxygen fuel pair”.

He also explained that at this time the next engine of this series is being assembled in the workshop of the enterprise.
