The RS-25 engine consists of pumps, valves, and other components working in concert to produce thrust. Fuel (liquid hydrogen) and oxidizer (liquid oxygen) from the Space Shuttle's external tank entered the orbiter at the umbilical disconnect valves and from there flowed through the orbiter's main propulsion system (MPS) feed lines; whereas in the Space Launch System (SLS), fuel and oxidizer ...

The AJ10-190 engines could be reused for up to 100 missions. Diagram of an RS-25 (or Space Shuttle Main Engine), that used a twin shaft staged combustion cycle. There were three of these on the back of the orbiter. Comparing the diagram of the RS-25 to that of the Orbital Manoeuvring System (OMS), it is clear that the RS-25 engine is far more ...
The ascent propulsion system (APS) or lunar module ascent engine (LMAE) is a fixed-thrust hypergolic rocket engine developed by Bell Aerosystems for use in the Apollo Lunar Module ascent stage. It used Aerozine 50 fuel, and N 2 O 4 oxidizer. Rocketdyne provided the injector system, at the request of NASA, when Bell could not solve combustion ...
If the surfaces contacting this oxygen were bare metal, they would corrode too quickly. The RD-180 solves this problem using an inert enamel coating on all metal surfaces in contact with the hot oxygen. [3] The movements of the engine nozzles are controlled by four hydraulic actuators. The engine can be throttled from 47% to 100% of nominal ...
The J-2X is a liquid-fueled cryogenic rocket engine that was planned for use on the Ares rockets of NASA's Constellation program, and later the Space Launch System.Built in the United States by Aerojet Rocketdyne (formerly, Pratt & Whitney Rocketdyne), the J-2X burns cryogenic liquid hydrogen and liquid oxygen propellants, with each engine producing 1,307 kN (294,000 lb f) of thrust in vacuum ...
The RD-0124 (Russian: Ракетный Двигатель-0124, romanized: Raketnyy Dvigatel-0124, lit. 'Rocket Engine 0124', GRAU index: 14D23) is a rocket engine burning liquid oxygen and kerosene in an oxygen-rich staged combustion cycle, developed by the Chemical Automatics Design Bureau in Voronezh.
With the SLS now using these engines, along with NASA's shift to using the RS-25 name, I think keeping the old SSME name is doing more harm than good. We don't call the F-1 the Saturn V main engine after all. It's much more concise to say, "the space shuttle used three RS-25s as its main engines," than it is to say, "the SLS will use four Space ...
