摘要： A turbine engine (49) fuel delivery system of the type including a pneumatic governor has an electronic governor and an engine excess stress avoidance feature which disable the pneumatic governor (70) so long as the engine speed exceeds a prescribed value and an electronic control unit (45) continues to function properly. The system transfers governing responsibility to the electronic control unit (45) which controls a torque motor and solenoid valve fuel diversion line (22). The system monitors an engine (49) operating parameter such as gas generator speed (37), power turbine speed, engine output torque, or engine temperature and further diminishes fuel flow to the engine (49) when the monitored parameter exceeds a threshold value. The system resumes normal speed governoring flow when that parameter returns to an acceptable level. The system also senses rotor blade pitch to reduce rotor droop and increases fuel flow to the engine (49) when the pitch (44) increases, and decreasing the fuel flow to the engine (49) when the rotor blade pitch (44) decreases.

摘要： Turbine gas temperature, which escalates during a compressor stall, is monitored 46, and compared to a set point temperature 52. If the set point temperature is exceeded, valve 36 is pulsed discharging fuel from line 24 and reducing flow to the combustor. Open and closed intervals are selected to reduce flow, but to avoid flameout. An additional second valve 42 operates in a similar mode in response to an even higher gas temperature.Engine operation continues in this temperature protection mode until the stall is corrected by whatever means.

摘要： In an aircraft, a fuel return valve (FRV) controls a flow of fuel, used to cool an oil feeding a propulsion engine and an oil of an integrated drive generator (IDG). A first sensor supplies measurements of the oil temperature at an output port of the IDG and a second sensor supplies measurements of oil temperature of the propulsion engine. An FRV operation monitoring system: determines, for each flight of the aircraft, an oil temperature maximum at an output port of the IDG and/or a maximum oil temperature of the propulsion engine; assesses a trend of one and/or the other of the oil temperature maxima over several flights; and generates an alarm when the trend of one and/or the other of the oil temperature maxima shows that a predetermined threshold has been exceeded.

摘要： A combustion staging system includes a splitting unit which receives a metered fuel flow and controllably splits the received fuel flow into pilot and mains flows. Pilot and mains fuel manifolds distribute fuel from the splitting unit to the pilot and mains stages. The splitting unit selects and deselects pilot-only operation. Both pilot and mains manifolds are selectable for pilot and mains operation. A cooling flow recirculation line has a delivery section arranged to provide a cooling flow of fuel to the mains manifold when it is deselected during pilot-only operation. Cooling flow enters the delivery section from a high pressure fuel zone of the engine and exits the return section to a low pressure fuel zone of the engine. A controller adjusts the splitting unit during pilot-only operation to partially select the mains manifold thereby increasing the pressure in the mains manifold to meet a target fuel pressure therein.

摘要： An ecology system includes an ecology tank, a check valve, a shutoff valve, and an ejector pump. The check valve is fluidly connected to the ecology tank and is configured to allow flow from the ecology tank. The shutoff valve is fluidly connected to the check valve, and the ejector pump is fluidly connected to the shutoff valve. The ejector pump is configured to draw fuel from the ecology tank when the shutoff valve is in an open configuration.

摘要： A fuel forwarding skid for delivering fuel from a storage area to a plurality of turbines includes at least two pumps for delivering fuel to a skid outlet line. A flow control device is connected to the pumps to control an output of the pumps. A recirculation line is in communication with the skid outlet line and is adapted to return a portion of the fuel in the skid outlet line to the storage area. A flow meter is in communication with the recirculation line to measure a rate of flow in the recirculation line, and the flow control device controls the output of at least one of the pumps in accordance with the rate of flow in the recirculation line.
