  2. Model rocket - Wikipedia

    en.wikipedia.org/wiki/Model_rocket

    Model rocketry is a safe and widespread hobby. Individuals such as G. Harry Stine and Vernon Estes helped to ensure this by developing and publishing the NAR Model Rocket Safety Codes [1] [13] [14] and by commercially producing safe, professionally designed and manufactured model rocket motors.

  3. Model rocket motor classification - Wikipedia

    en.wikipedia.org/wiki/Model_rocket_motor...

    The designation for a specific motor looks like C6-3.In this example, the letter (C) represents the total impulse range of the motor, the number (6) before the dash represents the average thrust in newtons, and the number (3) after the dash represents the delay in seconds from propelling charge burnout to the firing of the ejection charge (a gas generator composition, usually black powder ...

  5. Rocket engine - Wikipedia

    en.wikipedia.org/wiki/Rocket_engine

    A rocket engine is a reaction engine, producing thrust in accordance with Newton's third law by ejecting reaction mass rearward, usually a high-speed jet of high-temperature gas produced by the combustion of rocket propellants stored inside the rocket. However, non-combusting forms such as cold gas thrusters and nuclear thermal rockets also exist.

  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 ...

    en.wikipedia.org/wiki/BE-4

    The BE-4 (Blue Engine 4) [5] is an oxygen-rich, [6] liquefied-methane-fueled, staged-combustion, rocket engine. It is produced by Blue Origin. BE-4 was developed with private and public funding. [7] The engine produces 2,400 kilonewtons (550,000 lbf) of thrust at sea level. [8]

  8. SpaceX Merlin - Wikipedia

    en.wikipedia.org/wiki/SpaceX_Merlin

    The Merlin 1B rocket engine was an upgraded version of the Merlin 1A engine. The turbopump upgrades were handled by Barber-Nichols, Inc. for SpaceX. [ 10 ] It was intended for Falcon 1 launch vehicles, capable of producing 380 kN (85,000 lbf) of thrust at sea level and 420 kN (95,000 lbf) in vacuum, and performing with a specific impulse of 261 ...

  9. 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.
