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.
The booster would utilize multiple Raptor engines, similar to the use of nine Merlin 1s on each Falcon 9 booster core. [17] The following month, SpaceX confirmed that as of March 2014, all Raptor development work is exclusively on this single very large rocket engine, and that no smaller Raptor engines were in the current development mix.

The Raptor engine uses a full-flow staged combustion cycle with oxygen and methane-rich turbopumps. [27] [28] Before 2014, only two full-flow staged-combustion rocket engine designs had advanced enough to undergo testing: the Soviet RD-270 project in the 1960s and the Aerojet Rocketdyne Integrated Powerhead Demonstrator in the mid-2000s. [29]
In October 2012, SpaceX publicly announced concept work on a rocket engine that would be "several times as powerful as the Merlin 1 series of engines, and won't use Merlin's RP-1 fuel". [58] They indicated that the large engine was intended for a new SpaceX rocket, using multiple of these large engines could notionally launch payload masses of ...
Additionally, Elon Musk provided more details about the space mission architecture, launch vehicle, spacecraft, and Raptor engines. The first test firing of a Raptor engine on a test stand took place in September 2016. [36] [37] On September 26, 2016, a day before the 67th International Astronautical Congress, a Raptor engine fired for the ...
On 8 September 2005, SpaceX announced the development of the Falcon 9 rocket, which has nine Merlin engines in its first stage. [21] The design is an EELV -class vehicle, intended to compete with the Delta IV and the Atlas V , along with launchers of other nations as well.
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 (SLS), fuel and oxidizer ...
