  2. Solid-propellant rocket - Wikipedia

    en.wikipedia.org/wiki/Solid-propellant_rocket

    A solid-propellant rocket or solid rocket is a rocket with a rocket engine that uses solid propellants (fuel/oxidizer). The earliest rockets were solid-fuel rockets powered by gunpowder. The inception of gunpowder rockets in warfare can be credited to the ancient Chinese, and in the 13th century, the Mongols played a pivotal role in ...

  3. Rocket propellant - Wikipedia

    en.wikipedia.org/wiki/Rocket_propellant

    Solid fuel rockets have lower specific impulse, a measure of propellant efficiency, than liquid fuel rockets. As a result, the overall performance of solid upper stages is less than liquid stages even though the solid mass ratios are usually in the .91 to .93 range, as good as or better than most liquid propellant upper stages.

  4. Solid rocket booster - Wikipedia

    en.wikipedia.org/wiki/Solid_rocket_booster

    A solid rocket booster (SRB) is a solid propellant motor used to provide thrust in spacecraft launches from initial launch through the first ascent. 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.

  5. Ammonium perchlorate composite propellant - Wikipedia

    en.wikipedia.org/wiki/Ammonium_perchlorate...

    Ammonium perchlorate composite propellant (APCP) is a solid rocket propellant. It differs from many traditional solid rocket propellants such as black powder or zinc-sulfur, not only in chemical composition and overall performance but also by being cast into shape, as opposed to powder pressing as with black powder. This provides manufacturing ...

  6. Propellant - Wikipedia

    en.wikipedia.org/wiki/Propellant

    Rocket propellant may be expelled through an expansion nozzle as a cold gas, that is, without energetic mixing and combustion, to provide small changes in velocity to spacecraft by the use of cold gas thrusters, usually as maneuvering thrusters. To attain a useful density for storage, most propellants are stored as either a solid or a liquid.

    Solid propellants are a mixture of fuel and oxidiser. Metallic powders such as aluminium often serve as the fuel, and ammonium perchlorate, which is the salt of perchloric acid and ammonia, is the ...

  9. Solid fuel - Wikipedia

    en.wikipedia.org/wiki/Solid_fuel

    Solid fuels are extensively used in rocketry as solid propellants. [1] Solid fuels have been used throughout human history to create fire [2] and solid fuel is still in widespread use throughout the world in the present day. [3] [4] Solid fuel from biomass is regarded as a renewable energy source which can contribute to climate change ...
