A liquid fuel pressurization and control system is disclosed which utilizes either a helical flow pump, or a helical flow pump followed by a gear pump, to pressurize liquid fuel to precisely the pressure level required by a turbogenerator's combustor injectors. This eliminates the need to overpressurize the fuel then regulate the fuel pressure down using a flow control valve or a pressure control valve. The shaft torque and shaft speed of the pump are controlled by the turbogenerator's power controller so as to assure that the turbogenerator's speed is p...
[ What we claim is:] [1.] A method of liquid fuel pressurization and control for a turbogenerator supplied with liquid fuel by a pump disposed in a liquid fuel supply tank, comprising the steps of:establishing the turbogenerator speed and turbogenerator turbine exhaust temperature required based upon the power load requirements of the turbogenerator;establishing the liquid fuel pressure requirements to produce the established turbogenerator speed and operating temperature; andcommanding the pump to produce the established liquid fuel pressure by controll...
