  2. Liquid rocket propellant - Wikipedia

    en.wikipedia.org/wiki/Liquid_rocket_propellant

    About 170 different propellants made of liquid fuel have been tested, excluding minor changes to a specific propellant such as propellant additives, corrosion inhibitors, or stabilizers. In the U.S. alone at least 25 different propellant combinations have been flown. [2] Many factors go into choosing a propellant for a liquid-propellant rocket ...

  3. 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. RL10 versions were produced for the Centaur upper stage of the Atlas V and the DCSS of the Delta IV

    On the other hand, if the propellants are cooled sufficiently, they exist in the liquid phase at higher density and lower pressure, simplifying tankage. These cryogenic temperatures vary depending on the propellant, with liquid oxygen existing below −183 °C (−297.4 °F; 90.1 K) and liquid hydrogen below −253 °C (−423.4 °F; 20.1 K).

    Liquid propellants provide greater propulsive thrust and power, but require more complex technology and extra weight. Solid fuel is dense and burns quite quickly, generating thrust over a short time.

  6. Liquid rocket booster - Wikipedia

    en.wikipedia.org/wiki/Liquid_rocket_booster

    A liquid rocket booster (LRB) uses liquid fuel and oxidizer to give a liquid-propellant or hybrid rocket an extra boost at take-off, and/or increase the total payload ...

  7. Liquid-propellant rocket - Wikipedia

    en.wikipedia.org/wiki/Liquid-propellant_rocket

    A liquid-propellant rocket or liquid rocket uses a rocket engine burning liquid propellants. (Alternate approaches use gaseous or solid propellants.) Liquids are desirable propellants because they have reasonably high density and their combustion products have high specific impulse (I sp). This allows the volume of the propellant tanks to be ...

  8. Rotating detonation engine - Wikipedia

    en.wikipedia.org/wiki/Rotating_detonation_engine

    The engine used gaseous methane and oxygen as propellants, generating an average thrust of 518 N and delivering 290 seconds of specific impulse. Rotating combustion also created a torque of 0.26 N·m, so a S-shaped pulse detonation engine was used to reduce the spin of the stage. [27] [28]

  9. Vikas (rocket engine) - Wikipedia

    en.wikipedia.org/wiki/Vikas_(rocket_engine)

    The Vikas (a portmanteau from initials of VIKram Ambalal Sarabhai [5] [6]) is a family of hypergolic liquid fuelled rocket engines conceptualized and designed by the Liquid Propulsion Systems Centre in the 1970s. [7] [8] The design was based on the licensed version of the Viking engine with the chemical pressurisation system. [9]
