A Russia’s world’s most powerful rocket engine being produced by NPO Energomash at Khimki, Russia.
The latest upgraded version of RD-171MV, most powerful multi-combustion chambered liquid-fuel rocket engine is slated to be part of Russia’s next workhorse launch vehicle to power the new Soyuz-5 medium-class carrier rocket in 2019., and, later, a super heavy-lift rocket.
The engine, which has improved overheating protection and a new fully domestically-made fuel and oxygen regulation system, weights 10.3 tons and has a thrust of over 800 kN, slightly more than the RD-171M variant.
Its turbines and pumps produce an output of 180 MW, which is comparable to three nuclear-propelled icebreakers.
Also this year, Energomash has delivered 11 RD-180 engines for US Atlas space launch vehicles. Energomash has also delivered four RD-181 engines for its US partner Orbital ATK to be mounted on Antares carrier rockets.
