    摘要: An electronic control system for regulating the amount of torque applied by a starter/generator to a gas turbine engine during startup. The control system senses engine speed, compares the engine's actual acceleration with a predetermined acceleration, and adjusts the torque to the engine so that the engine accelerates along the predetermined schedule. The predetermined schedule is a function of the engine's speed or time, inlet conditions and oil temperature.

    摘要: A gerotor pump having reduced drag torque at low temperatures is disclosed. The pump includes a shaft journalled in the housing. Mounted on the shaft are a pair of axially space metallic port plates and disposed therebetween are metallic interior and exterior gears. A ceramic eccentric ring circumscribes the exterior gear to define a diametral clearance.

    摘要: The present invention provides a gas turbine engine surge control system comprising a pressure transducer positioned for sensing compressor discharge pressure, a hot wire anemometer positioned for sensing compressor discharge flow and temperature, means for electronically processing the signals from the sensors to obtain corrected compressor discharge flow without the use of look-up tables, and means for modulating a surge control valve based on corrected flow to prevent surge. The means for electronically processing said sensed signals incorporates means for canceling the dynamic response of the hot wire anemometer so as to have the effect of accelerating the response rate of the anemometer to match the response rate of the discharge pressure transducer.
