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. The cycle allows full flow of both propellants through the turbines; hence the name. NEW EDITION HOODIES ARE EXTRA HIGH QUALITY!! ! 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 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. Full-flow staged combustion (FFSC) is a twin-shaft staged combustion cycle that uses both oxidizer-rich and fuel-rich preburners. The earliest concepts for Raptor considered liquid hydrogen (LH 2) as fuel rather than methane. Full-flow staged combustion cycle Full-flow staged combustion rocket cycle.

With the full flow staged combustion cycle, you take two preburners, one that runs fuel rich and one that runs oxygen rich. The fuel rich preburner powers the fuel pump and the oxygen rich preburner powers the LOX. 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. [3] This "two shaft" solution solves problems that can be caused by leaky seals as explained in the video. There's a lot going on between the dual preburners, the coaxial swirl injecto.
