The cycle takes a small portion of hot exhaust gas from the rocket engine's combustion chamber and routes it through turbopump turbines to pump fuel before being exhausted (similar to the gas-generator cycle). Since fuel is exhausted, the tap-off cycle is considered an open-cycle engine. The cycle is c… diseases that cause bone pain

"To date, Firefly is the only organization to develop an orbital-class rocket engine utilizing the combustion tap-off cycle, and the only organization to develop a kerolox tap-off cycle engine. This engine type eliminates traditional gas generators and instead opts to "tap off" the main combustion chamber, utilizing the high heat and pressure within it to drive the pumps. This provides a slight increase in specific impulse and results in a dramatically simpler and light… " - Tap-off cycle rocket engine
