The gas-generator cycles uses a gas generator and a turbine to drive a pump, which transports the fuel into the [[Combustion Chamber|combustion chamber]]. The exhaust of the gas generator is vented outboards, contributing only little thrust. The gas-generator cycle has an upper limit for chamber pressure, as a higher chamber pressure requires more power for the pump, which means more fuel has to be burned inside the gas generator without producing thrust.

The propellants get partially combusted in one or more preburners and the exhaust products are routed through one or more [[Turbine|turbines]] and into the main combustion chamber, where they are finally combusted. This cycle allows high chamber pressures and this very high [[Specific impulse|specific impulse]].
