First RD-171MV engine firing test cycle completed

In late March 2021, NPO Energomash (part of Roscosmos) completed a cycle of firing tests of the first RD-171MV advanced liquid propellant rocket engine. All eight firing tests, carried out over three months, were successful, confirming the engine's operability and the correctness of the selected design and technological solutions.

NPO Energomash Director General Igor Arbuzov congratulated the staff on fire tests completion, since the creation of the engine and its further operation completely depends on the level of design and technological solutions, as well as on the quality of performance work related to the creation of the engine. ‘Now we can say - yes, the engine exists!’ - Igor Arbuzov added.

NPO Energomash Chief Designer Pyotr Lyovochkin stressed that the fire tests once again showed the ability of the enterprise to create the most advanced engines in the world. Pyotr Lyovochkin noted that everyone in the company needs to constantly think about quality whether it is a designer, engineer, technologist, test engineer, or worker. The engine should continue to operate the same way it has shown itself.

The next stage of work will be the delivery of the RD-171MV engine to the Progress Rocket and Space Center (Samara, part of Roscosmos) for conducting a number of tests as part of the first stage of the Soyuz-5 perspective launch vehicle.
