RD-107А/RD-108А rocket engines produced in batches by Samara-based facility of Rostec’s United Engine Corporation allowed Soyuz-2.1a rocket with Progress MS-22 cargo spacecraft to be successfully launched. More than 2.5 tons of cargo will be delivered to the International Space Station.
Soyuz-2.1a rocket with Progress MS-22 cargo spacecraft was launched on February 9 at 09:15 Moscow Time from launch complex No.31 at Baikonur Cosmodrome. UEC-Kuznetsov’s RD-107А/RD-108А rocket engines installed on launch vehicle stages I and II worked satisfactorily.
The cargo spacecraft will deliver more than 2.5 tons of cargo to the International Space Station. The cargo is necessary to maintain the manned flight and implement Russian applied scientific research program.
This was the first launch of Soyuz-2 type rocket with engines produced in batches at UEC-Kuznetsov in this year. Stages I and II of all R-7 type launch vehicles, including RN type Soyuz-2, have been furnished with RD-107А/108А propulsion modifications since 1958. Batch production of these engines is currently established at UEC-Kuznetsov PJSC under the design supervision by the engine designer – Glushko SPA Energomash OJSC. Statistical product reliability exceeds 99.9%.
