  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 rockets use propellant in the solid phase, liquid fuel rockets use propellant in the liquid phase, gas fuel rockets use propellant in the gas phase, and hybrid rockets use a combination of solid and liquid or gaseous propellants. In the case of solid rocket motors, the fuel and oxidizer are combined when the motor is cast.

  4. 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.

  5. Graphite-Epoxy Motor - Wikipedia

    en.wikipedia.org/wiki/Graphite-Epoxy_Motor

    The Graphite-Epoxy Motor (GEM) is a family of solid rocket boosters developed in the late 1980s and used since 1990. GEM motors are manufactured with carbon-fibre-reinforced polymer casings and a fuel consisting of HTPB-bound ammonium perchlorate composite propellant. GEM is produced by Northrop Grumman Space Systems. [1]

  6. Dual-thrust rocket motor - Wikipedia

    en.wikipedia.org/wiki/Dual-thrust_rocket_motor

    In a dual-thrust solid propellant rocket engine, the propellant mass is composed of two different types (densities) of fuel. In the case of a tandem dual-thrust motor, the fuel nearest to the rocket nozzle burns fast, and the fuel further into the motor's body burns slower. This gives the rocket higher thrust initially, accelerating it rapidly ...

  7. P120C - Wikipedia

    en.wikipedia.org/wiki/P120C

    The P120C is a solid-fuel rocket motor designed for use as the first stage of the Vega-C and as the boosters of the Ariane 6 launch vehicles. The solid rocket motors were developed by Europropulsion, a joint venture of Avio and ArianeGroup, for the European Space Agency. The "C" in the name signifies its "Common" use across these vehicles.

    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. Gas Dynamics Laboratory - Wikipedia

    en.wikipedia.org/wiki/Gas_Dynamics_Laboratory

    The GDL utilised smokeless (TNT) gunpowder on a non-volatile solvent for solid propellant rockets. The first test-firing of a solid fuel rocket was carried out in March 1928, which flew for about 1,300 meters [4] In 1931 the world's first successful use of rockets to assist take-off of aircraft were carried out on a U-1, the Soviet designation for an Avro 504 trainer, which achieved about one ...
