Fire tests of second engine for “Soyuz-5 missile”

In the Scientific and Test Complex of the Scientific and Production Association “Energomash” named after Academician V.P. Glushko (part of the state corporation “Roscosmos”) ended fire tests of the second RD-171MV rocket engine. The test program is fully fulfilled. Tests passed in normal mode.

In the near future, NGO Energomash will send the engine RD-171MV to the city of Samara. In the Rocket and Space Center “Progress” (Samara, enters Roscosmos) to build the first stage of the Soyuz-5 missile, and the engine will be held another series of tests in the first stage of the rocket.

“The Soyuz-5 carrier rocket will be able to remove up to 17 tons of payload to a low near-earth orbit, and using an accelerated unit – up to 5 tons to geo-anddeal and up to 2.5 tons per geostationary orbit. Universal rocket for different tasks. Our company strictly withstands all dates for the manufacture of engines so that in 2023 “Soyuz-5” began to undergo flight tests. Now the following copies of the RD-171MV are collected at the species of our assembly workshop, and production shops make items for nodes and engine units that will rise. For the next year, “said Igor Arbuzov, General Director of NGO Energomash.

RD-171MV is the most powerful liquid rocket engine designed, manufactured and tested on NGO Energomash for the first stage of the Soyuz-5 carrier missile.

RD-171MV – Modification of the engine RD-170/171, which was created in the middle of the 1980s as part of the Energy – Buran program and provided two launch of the energy missile “Energy”. In addition, it was successfully applied to the rocket of the middle class “Zenit” until the completion of its operation in the projects “Sea Start” (the last start took place in May 2014) and the “ground start” (December 2017).

is a new engine. Unlike the predecessors of the RD-171MV, there has new executive mechanisms of the management system, improved protection against fire and a modern system of emergency protection. It is below the temperature on the turbine, the most stressful element of the engine design, which increases its resource. At the same time, the engine remains the same, and the specific impulse of the traction became higher. The design of this engine in the “digital” actually simplifies the further modernization of its aggregates, “Petr Levochkin said, the main designer of NGO Energomash.

Designing of the RD-171MV Designers of NGO Energomash was carried out in a cross-cutting system of automated design, which provides for the creation of a 3D model – original design documentation used and designers, and technologists.
