    摘要： In a gas-turbine engine control system, a temperature of the air supplied to mixers and a pressure of the fuel supplied to the mixers are detected and based on the detected fuel pressure, a flow rate of the fuel supplied to the mixers is determined based on at least the detected pressure of the fuel. Then, an adiabatic flame temperature in a combustion chamber is determined based on at least the determined flow rate of the fuel and it is determined whether a selected one of combustion modes including premixed combustion and diffusive combustion is to be switched to other based on the determined adiabatic flame temperature and the detected air temperature and the selected combustion mode is controlled to switch to the other in response to a result of determination. With this, it becomes possible to achieve switchover to the stabler combustion mode and realize better low emission performance by utilizing the premixed combustion range.

    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： A control system and method for controlling the split between premix fuel flow and pilot fuel flow to a combustor in a gas turbine engine so that an acceptable emissions are maintained. Engine speed and exhaust gas temperature are used to obtain a combustor pilot zone temperature that will result in the desired level of emissions. From this pilot zone temperature a desired split between premix fuel flow and pilot fuel flow is obtained and compared to the actual split to generate an error signal. The actual premix fuel flow and pilot fuel flow are then adjusted until the desired split and hence the desired emission levels are obtained.

    摘要： A fuel delivery system provides for closed loop mass flow control of fuel between a metering valve and a pump, such as a variable delivery pump. Changes in pressure across the metering valve are monitored and pump operation is altered in response thereto. A thermal controller monitors fuel temperature and recirculates a portion of the fuel flow through a heat exchanger. The fuel delivery system can be provided as original equipment or as a retrofit.

    摘要： An overthrust protection system for a gas turbine in which fuel is supplied at a controlled flow rate to a combustor (4) of the gas turbine. The overthrust protection system uses a bypass valve (24) to divert fuel flow away from the combustor (4). The opening of this valve is controlled by an overthrust controller (28) to divert fuel flow in response to a detected overthrust condition of the gas turbine. Diverting some of the fuel flow in this manner brings about a reduction in the thrust, allowing the overthrust condition to be controlled without resorting to a complete shut down of the gas turbine.

    摘要： A method for controlling an aircraft engine using a control system enables an engine to be operated at low power while hail is ingested. The control system includes a processor coupled to the aircraft engine. The method comprises receiving a plurality of sensed inputs from the aircraft engine, receiving current engine environmental operating conditions, determining a reference value for a controlled variable from a fuel flow schedule, generating a fuel-air-ratio for the reference value based on current engine environmental operating conditions, and enriching combustor fuel staging in response to the fuel-air-ratio.

    摘要： The invention relates to a fuel supply system (1) that supplies a fuel to a burner arrangement (8) with at least one burner (7), in particular a gas turbine (10). The fuel supply system (1) has at its input a control valve (3) that feeds the fuel into the fuel supply system (1) as a function of its actuation. As a function of a requested burner output, a first setpoint is determined for a fuel mass flow with which the burner arrangement (8) must be supplied in order to be able to furnish the required burner output. As a function of this first setpoint of the fuel mass flow a second setpoint is determined for the fuel mass flow, which is fed into the fuel supply system (1) by an actuation of the control valve (3). The second setpoint of the fuel mass flow is selected such that the fuel supply system (1) fed therewith supplies the burner arrangement (8) with the first setpoint of the fuel mass flow.
