摘要： An electronic fuel control for a gas turbine engine monitors the mass density of the fuel. As the mass density of the fuel varies when the fuel temperature changes or when the fuel type changes, the electronic fuel control adjusts an initial mass density to a corrected value based on the most recent measurement of mass fuel flow that was taken when the mass fuel flow measurement was known to be accurate. Accurately controlling mass fuel flow permits gas turbine engine designers to reduce tolerances in moving parts which improves the efficiency of the gas turbine engine.

摘要： The angle of the variable blocker door vanes in the bypass duct of a turbofan engine is varied in response to the angle of the variable compressor vanes of the engine. A cam and linkage assembly interconnect the blocker doors with the actuation system of the variable stator vanes such that as the angle of the stator vanes is modulated through a first predetermined range, the angle of the blocker doors is modulated through a second predetermined range.

摘要： A method of detecting hydraulic leaks from a high pressure fuel hydraulic system is useful in systems where a pump, actuators, and hydraulic lines are filled with engine fuel at high pressure. The method comprises the steps of calculating pump flow based on a core engine RPM and a pump displacement, and calculating actuator fluid flow. System condition signals are then generated to indicate whether the core engine RPM is constant and whether the actuators are quiescent. A servo flow value is then provided, typically at predetermined system conditions, as indicated by the system condition signals, using the pump flow calculation and the actuator fluid flow calculation. Finally, leak flow is determined based on the pump flow calculation, the actuator fluid flow calculation, and the servo flow value, and the leak flow is responded to accordingly.

摘要： A method of controlling a system is adapted to control flow to throat nozzle and vectoring nozzle actuators. The method comprises the steps of summing a plurality of signals representative of flow to the vectoring nozzle actuators with a signal representative of flow to the throat nozzle actuators to generate a total hydraulic flow signal. The total flow signal is then compared to a signal representative of total pump output to generate a reserve signal. Finally, a scaled rate limit signal is generated from the reserve signal and multiplied by predetermined ratio signals such that the ratio signals are limited by the difference between pump output and pump demand.

摘要： The reliability of a fluid multiplexed actuation system is increased by arranging a pair of fluidic multiplexers in a parallel fluid flow path between a selector valve and several fluid actuators. Position sensors associated with the fluidic multiplexers and with the fluid actuators provide feedback signals to a microprocessor. In the event the feedback signals identify a malfunction in the fluidic multiplexer currently supplying fluid to the actuators, the microprocessor will deactivate the malfunctioning fluidic multiplexer and activate a redundant or back-up fluidic multiplexer by actuating the selector valve.
