  • Closed loop fuel control method
    Patent number: 5303541
    Abstract: A fuel control system for accurately controlling the fuel flow rate to a gas turbine engine during the initial stages of startup is provided. The fuel control system has a novel, closed control loop that measures the actual fuel flow rate to the primary nozzles of the engine, and uses this measurement to trim the commanded fuel flow rate signal generated by preprogrammed schedules in the engine's electronic control unit. By the novel arrangement of proportional and integral controllers, the fuel control system maintains a forward path gain of unity while permitting the independent adjustment of the gain of the controllers to achieve the system stability and response necessary for quick correction of fuel flow rate errors.
    Type: Grant

  • Gear pump having improved low temperature operation
    Patent number: 5076770
    Abstract: A gear pump having improved low-temperature operation includes a housing with a cavity wherein is rotatably received a pair of meshed pinion gears. A pair of bushing members matched in external shape to a projection of the pair of gears and complementary to the housing cavity alone journal the pair of gears. The bushings and gears are freely movable relative to the housing at all operating temperatures for the pump, and the bushings are urged by fluid pressure forces into sealing cooperation with the gears and with the housing. The pump achieves an improved pumping volume by directing a trapped intermesh volume to the outlet port of the pump.
