  2. Liquid rocket booster - Wikipedia

    en.wikipedia.org/wiki/Liquid_rocket_booster

    Launch of Ariane 44LP two solid rocket booster (smaller) and two liquid rocket boosters (larger, with no visible plumes) For the Cold War era R-7 Semyorka missile, which later evolved into the Soyuz rocket, this concept was chosen because it allowed all of its many rocket engines to be ignited and checked for function while on the launch pad.

  3. Rocket propellant - Wikipedia

    en.wikipedia.org/wiki/Rocket_propellant

    The rocket is launched using liquid hydrogen and liquid oxygen cryogenic propellants. Rocket propellant is used as reaction mass ejected from a rocket engine to produce thrust. The energy required can either come from the propellants themselves, as with a chemical rocket, or from an external source, as with ion engines.

  4. Polybutadiene acrylonitrile - Wikipedia

    en.wikipedia.org/wiki/Polybutadiene_acrylonitrile

    Polybutadiene acrylonitrile (PBAN) [1] copolymer, also noted as polybutadiene—acrylic acid—acrylonitrile terpolymer [2] is a copolymer compound used most frequently as a rocket propellant fuel mixed with ammonium perchlorate oxidizer. [3] It was the binder formulation widely used on the 1960s–1970s big boosters (e.g., Titan III and Space ...

  5. Rocket-assisted projectile - Wikipedia

    en.wikipedia.org/wiki/Rocket-assisted_projectile

    Also the German Krupp K5 railway gun of World War 2 used rocket-assisted projectiles in the later stages of the war, although it also used conventional artillery projectiles. The North Korean M-1978 / M-1989 Koksan 170 mm (6.7-inch) self-propelled gun can use rocket-assisted projectiles to achieve a range of around 60 kilometres (37 mi); at one ...

  6. 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]

  7. Comparison of orbital launch systems - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_orbital...

    Hybrid-propellant rockets use a combination of solid and liquid propellant, typically involving a liquid oxidizer being pumped through a hollow cylinder of solid fuel. All current spacecraft use conventional chemical rockets (solid-fuel or liquid bipropellant) for launch, though some [note 3] have used air-breathing engines on their first stage ...

  8. SEPR 84 - Wikipedia

    en.wikipedia.org/wiki/SEPR_84

    The SEPR 84 is a family of liquid-propellant rocket engines used as boosters for the Dassault Mirage III mixed-power high-altitude interceptor aircraft of the 1960s. The engine was one of several similar developed by SEPR ( Société d'Etudes pour la Propulsion par Réaction ).

  9. AJ-60A - Wikipedia

    en.wikipedia.org/wiki/AJ-60A

    The AJ-60A rocket motor was developed between 1999 and 2003 for use on the Atlas V. [2] On January 19, 2006 the New Horizons spacecraft to Pluto was launched directly into a solar-escape trajectory at 16.26 kilometers per second (58,536 km/h; 36,373 mph) from Cape Canaveral using an Atlas V version with 5 of these SRBs and Star 48B third stage.
