Liquid rocket fuel. Oxidizer. Pumps carry the fuel and oxidizer. The combustion chamber mixes and burns the two liquids. The hot exhaust is choked at the throat, which, among other things, dictates the amount of thrust produced. Exhaust exits the rocket.
Archimedes is presented as a highly reusable liquid-propellant engine using methane and liquid oxygen in an oxidizer-rich staged combustion cycle. [1] [2] There are both sea-level and vacuum variants. The engine is mostly 3D printed, [7] with some of the biggest 3D printers in the world. The rationale for the cycle change from the original gas ...
Raptor is a family of rocket engines developed and manufactured by SpaceX. It is the third rocket engine in history designed with a full-flow staged combustion (FFSC) fuel cycle, and the first such engine to power a vehicle in flight. [15] The engine is powered by cryogenic liquid methane and liquid oxygen, a combination known as methalox.
Raptor is a family of methane/liquid oxygen rocket engines under development by SpaceX since the late 2000s, [2] although LH2/LOX propellant mix was originally under study when the Raptor concept development work began in 2009. [15] When first mentioned by SpaceX in 2009, the term "Raptor" was applied exclusively to an upper stage engine ...
A liquid-propellant rocket or liquid rocket uses a rocket engine burning liquid propellants. (Alternate approaches use gaseous or solid propellants.) Liquids are desirable propellants because they have reasonably high density and their combustion products have high specific impulse (I sp). This allows the volume of the propellant tanks to be ...
Using liquid methane and liquid oxygen as propellants is sometimes called methalox propulsion. [19] Liquid methane has a lower specific impulse than liquid hydrogen, but is easier to store due to its higher boiling point and density, as well as its lack of hydrogen embrittlement. It also leaves less residue in the engines compared to kerosene ...
A second attempt, without real satellites, in July made LandSpace the world's first company to launch methane-liquid oxygen rocket, ahead of U.S. rivals including Musk's SpaceX and Jeff Bezos ...
In May 2019, LandSpace performed test firings of its liquid-methane and liquid-oxygen fuelled TQ-12 rocket engine at its test facility at Huzhou, Zhejiang province. LandSpace's head of research and development, Ge Minghe, says that the engine has a thrust of 80 tonnes-force. The Huzhou facility will be able to produce about 15 ZQ-2 rockets and ...
