Bipropellant liquid rockets use a liquid fuel such as liquid hydrogen or RP-1, and a liquid oxidizer such as liquid oxygen. The engine may be a cryogenic rocket engine , where the fuel and oxidizer, such as hydrogen and oxygen, are gases which have been liquefied at very low temperatures.
Liquid rocket propellant. The highest specific impulse chemical rockets use liquid propellants ( liquid-propellant rockets ). They can consist of a single chemical (a monopropellant) or a mix of two chemicals, called bipropellants. Bipropellants can further be divided into two categories; hypergolic propellants, which ignite when the fuel and ...
Liquid oxygen is the most common cryogenic liquid oxidizer propellant for spacecraft rocket applications, usually in combination with liquid hydrogen, kerosene or methane. [11] [12] Liquid oxygen was used in the first liquid fueled rocket. The World War II V-2 missile also used liquid oxygen under the name A-Stoff and Sauerstoff.
Rocket propellant. A Delta IV Heavy during liftoff. The rocket is entirely fuelled with liquid hydrogen and liquid oxygen cryogenic propellants. Rocket propellant is the reaction mass of a rocket. This reaction mass is ejected at the highest achievable velocity from a rocket engine to produce thrust. The energy required can either come from the ...
Archimedes is a liquid-fuel rocket engine burning liquid oxygen and liquid methane in an oxidizer-rich staged combustion cycle. [ 1 ] [ 2 ] It is designed by aerospace company Rocket Lab for its Neutron rocket.
SpaceX Raptor. Raptor is a family of rocket engines developed and manufactured by SpaceX. A notable trait of this engine family is the use of a full-flow staged combustion cycle (FFSC). They are powered by cryogenic liquid methane and liquid oxygen, a mixture known as methalox. SpaceX's super-heavy-lift Starship uses Raptor engines in its Super ...
The RS-25, also known as the Space Shuttle Main Engine ( SSME ), [ 1] is a liquid-fuel cryogenic rocket engine that was used on NASA 's Space Shuttle and is used on the Space Launch System (SLS). Designed and manufactured in the United States by Rocketdyne (later Pratt & Whitney Rocketdyne and Aerojet Rocketdyne ), the RS-25 burns cryogenic ...
A cryogenic rocket engine is a rocket engine that uses a cryogenic fuel and oxidizer; that is, both its fuel and oxidizer are gases which have been liquefied and are stored at very low temperatures. [ 1] These highly efficient engines were first flown on the US Atlas-Centaur and were one of the main factors of NASA 's success in reaching the ...
