Konstantin Tsiolkovsky proposed the use of liquid propellants in 1903, in his article Exploration of Outer Space by Means of Rocket Devices. [3] [4] On March 16, 1926, Robert H. Goddard used liquid oxygen (LOX) and gasoline as propellants for his first partially successful liquid-propellant rocket launch. Both propellants are readily available ...
The Aerojet Rocketdyne AR1 is a 2,200-kilonewton-class (500,000 lbf) thrust RP-1/LOX oxidizer-rich staged combustion cycle rocket engine project. [1]The engine was conceived in 2014, and received US government funding to build a prototype engine in 2016. [2]
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]
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.

Aerojet Rocketdyne is a subsidiary of American defense company L3Harris that manufactures rocket, hypersonic, and electric propulsive systems for space, defense, civil and commercial applications. [ 3 ] [ 4 ] [ 2 ] Aerojet traces its origins to the General Tire and Rubber Company (later renamed GenCorp, Inc. as it diversified) established in ...
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.
