  2. Integrated Powerhead Demonstrator - Wikipedia

    en.wikipedia.org/wiki/Integrated_powerhead...

    On July 19, 2006 Rocketdyne announced that the demonstrator engine front-end had been operated at full capacity. [3]According to NASA, the Integrated Powerhead Demonstrator project was the first of three potential phases of the Integrated High Payoff Rocket Propulsion Technology Program, which was aimed at demonstrating technologies that double the capability of state-of-the-art cryogenic ...

  3. Reaction engine - Wikipedia

    en.wikipedia.org/wiki/Reaction_engine

    A reaction engine is an engine or motor that produces thrust by expelling reaction mass (reaction propulsion), [1] in accordance with Newton's third law of motion.This law of motion is commonly paraphrased as: "For every action force there is an equal, but opposite, reaction force."

  4. Aerojet Rocketdyne AR1 - Wikipedia

    en.wikipedia.org/wiki/Aerojet_Rocketdyne_AR1

    Aerojet Rocketdyne proposed in 2014 to "lobby the government to fund an all-new, U.S.-sourced rocket propulsion system." In June 2014, Aerojet initially projected it would cost under US$25 million per pair of engines, not including the up to US$1 billion estimated development cost to be funded by the government.

  5. Pulsed plasma thruster - Wikipedia

    en.wikipedia.org/wiki/Pulsed_plasma_thruster

    A pulsed plasma thruster (PPT), also known as a Pulsed Plasma Rocket (PPR), or as a plasma jet engine (PJE), is a form of electric spacecraft propulsion. [1] PPTs are generally considered the simplest form of electric spacecraft propulsion and were the first form of electric propulsion to be flown in space, having flown on two Soviet probes ...

  6. Liquid apogee engine - Wikipedia

    en.wikipedia.org/wiki/Liquid_Apogee_Engine

    A liquid apogee engine (LAE), or apogee engine, refers to a type of chemical rocket engine typically used as the main engine in a spacecraft. The name apogee engine derives from the type of manoeuvre for which the engine is typically used, i.e. an in-space delta-v change made at the apogee of an elliptical orbit in order to circularise it.

  7. RL10 - Wikipedia

    en.wikipedia.org/wiki/RL10

    The RL10 is a liquid-fuel cryogenic rocket engine built in the United States by Aerojet Rocketdyne that burns cryogenic liquid hydrogen and liquid oxygen propellants. Modern versions produce up to 110 kN (24,729 lb f) of thrust per engine in vacuum.

  8. Spacecraft flight dynamics - Wikipedia

    en.wikipedia.org/wiki/Spacecraft_flight_dynamics

    A space vehicle's flight is determined by application of Newton's second law of motion: =, where F is the vector sum of all forces exerted on the vehicle, m is its current mass, and a is the acceleration vector, the instantaneous rate of change of velocity (v), which in turn is the instantaneous rate of change of displacement.

  9. Air-augmented rocket - Wikipedia

    en.wikipedia.org/wiki/Air-augmented_rocket

    The first [4] serious attempt to make a production air-augmented rocket was the Soviet Gnom rocket design, implemented by Decree 708-336 of the Soviet Ministers of 2 July 1958. More recently, about 2002, NASA has re-examined similar technology for the GTX program as part of an effort to develop SSTO spacecraft.
