  2. Aerospike engine - Wikipedia

    en.wikipedia.org/wiki/Aerospike_engine

    The aerospike engine is a type of rocket engine that maintains its aerodynamic efficiency across a wide range of altitudes. [1] It belongs to the class of altitude compensating nozzle engines. [2] Aerospike engines were proposed for many single-stage-to-orbit (SSTO) designs. They were a contender for the Space Shuttle main engine. However, as ...

  4. Orbital Maneuvering System - Wikipedia

    en.wikipedia.org/wiki/Orbital_Maneuvering_System

    The Orbital Maneuvering System (OMS) is a system of hypergolic liquid-propellant rocket engines used on the Space Shuttle and the Orion spacecraft.Designed and manufactured in the United States by Aerojet, [1] the system allowed the orbiter to perform various orbital maneuvers according to requirements of each mission profile: orbital injection after main engine cutoff, orbital corrections ...

  5. Solid rocket booster - Wikipedia

    en.wikipedia.org/wiki/Solid_rocket_booster

    Many launch vehicles, including the Atlas V, [1] SLS and Space Shuttle, have used SRBs to give launch vehicles much of the thrust required to place the vehicle into orbit. The Space Shuttle used two Space Shuttle SRBs , which were the largest solid propellant motors ever built until the Space Launch System and the first designed for recovery ...

  6. RS-25 - Wikipedia

    en.wikipedia.org/wiki/RS-25

    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 ...

  7. Gimbaled thrust - Wikipedia

    en.wikipedia.org/wiki/Gimbaled_thrust

    In a gimbaled thrust system, the engine or just the exhaust nozzle of the rocket can be swiveled on two axes (pitch and yaw) from side to side. As the nozzle is moved, the direction of the thrust is changed relative to the center of gravity of the rocket. The diagram illustrates three cases.

  8. Two-stage-to-orbit - Wikipedia

    en.wikipedia.org/wiki/Two-stage-to-orbit

    As of 2023, SpaceX and NASA are the only launch providers which have achieved first-stage reuse of an orbital vehicle with SpaceX’s two-stage Falcon 9 and 2.5-stage Falcon Heavy, and NASA’s Space Shuttle Solid Rocket Boosters. Rocket Lab has recovered multiple first stages of their Electron rocket, but has not flown it again.

  9. Rocketdyne F-1 - Wikipedia

    en.wikipedia.org/wiki/Rocketdyne_F-1

    The Vulcain for the Ariane 5 rocket uses a similar cycle design to F-1 engine, with the turbine exhaust gases piped directly overboard. As part of the Space Launch System (SLS) program, NASA had been running the Advanced Booster Competition, which was scheduled to end with the selection of a winning booster configuration in 2015.
