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.
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 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 ...
The TM65 uses a 75% ethanol/water mixture for fuel and liquid oxygen (LOX) for oxidizer. [4] It has a regeneratively cooled nozzle. Nitrogen was used in the first tests to pressurize the propellant tanks, heated in a heat exchanger in the nozzle.
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 ...
In July, LandSpace hit a benchmark in that race with the launch of the world's first methane-liquid oxygen rocket, the Zhuque-2 Y-2, putting China ahead of U.S. rivals including SpaceX and Jeff ...
Liquid rocket engines have tankage and pipes to store and transfer propellant, an injector system and one or more combustion chambers with associated nozzles.. Typical liquid propellants have densities roughly similar to water, approximately 0.7 to 1.4 g/cm 3 (0.025 to 0.051 lb/cu in).
Sky Lark 12) is a gas-generator cycle rocket engine burning liquid methane and liquid oxygen (methalox) developed by LandSpace. [4] TQ-12 is the first Chinese liquid rocket engine developed with private funding. [5] The engine has been designed to produce 670 kilonewtons (150,000 lbf) of thrust at sea level. [6]
