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 ...
An example of a specific impulse measured in time is 453 seconds, which is equivalent to an effective exhaust velocity of 4.440 km/s (14,570 ft/s), for the RS-25 engines when operating in a vacuum. [36]

Propelled by 4 RS-25 engines, the stage generates approximately 7.44 MN (1,670,000 lb f) of thrust, about 25% of the Space Launch System's thrust at liftoff, for approximately 500 seconds, propelling the stage alone for the last 375 seconds of flight. The stage lifts the rocket to an altitude of approximately 162 km (531,380 ft) before ...
The RS-25 Space Shuttle main engine is another example of a staged combustion engine, and the first to use liquid oxygen and liquid hydrogen. [4] Its counterpart in the Soviet shuttle was the RD-0120 , which had similar specific impulse , thrust, and chamber pressure, but with some differences that reduced complexity and cost at the expense of ...
The RS-25 engine designed for the Space Shuttle uses a system of fluted posts, ... High specific impulse; high combustion chamber pressures allowing for high thrust
Unlike their 2020 research that found no significant relationship between overall PM2.5 and childhood cognition, this new analysis focused on 15 specific chemical components within PM2.5.
Specific impulse, vacuum: ... fit on top of the 8.4 meter diameter core stage with four RS-25 Space Shuttle ... Specific impulse: 433 seconds (4.25 km/s ...
