A turbopump is a propellant pump with two main components: a rotodynamic pump and a driving gas turbine, usually both mounted on the same shaft, or sometimes geared together.They were initially developed in Germany in the early 1940s. The purpose of a turbopump is to produce a high-pressure fluid for feeding a combustion chamber or other use.

Merlin is a family of rocket engines developed by SpaceX for use on its Falcon 1, Falcon 9 and Falcon Heavy launch vehicles. Merlin engines use RP-1 and liquid oxygen as rocket propellants in a gas-generator power cycle. The Merlin engine was originally designed for sea recovery and reuse, but since 2016 the entire Falcon 9 booster is recovered for reuse by landing vertically on …

The J-2 is a liquid-fuel cryogenic rocket engine used on NASA's Saturn IB and Saturn V launch vehicles. The engine's preliminary design dates back to recommendations of the 1959 Silverstein Committee.Rocketdyne won approval to develop the J-2 in June 1960 and the first flight, AS-201, occurred on 26 February 1966.The J-2 underwent several minor upgrades over its operational …

The PGM-17A Thor was the first operational ballistic missile of the United States Air Force (USAF). Named after the Norse god of thunder, it was deployed in the United Kingdom between 1959 and September 1963 as an intermediate-range ballistic missile (IRBM) with thermonuclear warheads.Thor was 65 feet (20 m) in height and 8 feet (2.4 m) in diameter.

The RS-25 engine consists of pumps, valves, and other components working in concert to produce thrust. Fuel (liquid hydrogen) and oxidizer (liquid oxygen) from the Space Shuttle's external tank entered the orbiter at the umbilical disconnect valves and from there flowed through the orbiter's main propulsion system (MPS) feed lines; whereas in the Space Launch System …

The English Electric Lightning is a British fighter aircraft that served as an interceptor during the 1960s, the 1970s and into the late 1980s. It remains the only UK-designed-and-built fighter capable of Mach 2.The Lightning was designed, developed, and manufactured by English Electric, which was later merged into the newly-formed British Aircraft Corporation.

As regards the new European medium-heavy Ariane 6 launcher, Avio is responsible for the P120C solid-propellant motor (common to the first stage of the Vega C), which will act as a booster for the launcher (in dual configuration for the medium Ariane 62 version and in quadruple configuration for the heavy Ariane 64 version), and the liquid-oxygen turbopump (LOX) for the …

The Blue Engine 4 or BE-4 is an oxygen-rich liquefied-methane-fueled staged-combustion rocket engine under development by Blue Origin.The BE-4 is being developed with private and public funding. The engine has been designed to produce 2.4 meganewtons (550,000 lbf) of thrust at sea level.. It was initially planned for the engine to be used exclusively on a Blue Origin …

Rotary Rocket Company was an aerospace company in the late 1990s. Its founders were among the first to recognize that the end of the Cold War represented a significant shift away from the militarization of space, to a new civilian-led, commercial space industry. In 1996, Rotary Rocket Company was formed to address this emerging market.
