The SpaceX Raptor is a full-flow, staged-combustion, methane-fueled rocket engine manufactured by SpaceX.The engine is powered by cryogenic liquid methane and liquid oxygen (LOX), rather than the RP-1 kerosene and LOX used in SpaceX's prior Merlin and Kestrel rocket engines. The fuel rich preburner powers the fuel pump and the oxygen rich preburner powers the LOX.

With the full flow staged combustion cycle, you take two preburners, one that runs fuel rich and one that runs oxygen rich. Full-flow staged combustion cycle Full-flow staged combustion rocket cycle. This "two shaft" solution solves problems that can be caused by leaky seals as explained in the video. NEW EDITION HOODIES ARE EXTRA HIGH QUALITY!! The full flow staged combustion cycle is the most complex and advanced rocket engine, and SpaceX's Raptor engine will be the first to be operational. For a Full FLow Staged Combustion Cycle engine there are two combustion chambers driving two turbines; one to drive the fuel pump, and the other to drive the oxidizer pump. The full flow staged combustion cycle is the most complex and advanced rocket engine, and SpaceX's Raptor engine will be the first to be operational. There's a lot going on between the dual preburners, the coaxial swirl injecto. [3] The earliest concepts for Raptor considered liquid hydrogen (LH 2) as fuel rather than methane. The cycle allows full flow of both propellants through the turbines; hence the name. Full-flow staged combustion (FFSC) is a twin-shaft staged combustion cycle that uses both oxidizer-rich and fuel-rich preburners. !
