For high-thrust, long-duration liquid-propellant rocket engines, the use of turbopump-fed systems usually lowers system weight and raises performance as compared to pressurized-gas fed systems. Turbopump-fed systems require only relatively low pump-inlet pressures, and thus propellant-tank pressures, while the major portion of the pressure required at the thrust-chamber inlets is supplied by the pumps. This saves considerable tank weight, particularly in large vehicles.
