摘要:
A control system for a gas turbine engine, a method for controlling a gas turbine engine, and a gas turbine engine are disclosed. The control system may include a nozzle scheduler for determining an exhaust nozzle position goal based on a nozzle schedule of exhaust nozzle positions related to flight conditions. The control system may further include a control module for determining a control command for the gas turbine engine. The control command may include, at least, a fuel flow command and an exhaust nozzle position command and the control command may be based on, at least, the exhaust nozzle position goal and an estimated thrust value. The control system may further include an actuator for controlling the gas turbine engine based on the control command.
摘要:
A control device for controlling a variable section nozzle of an aircraft power plant, the variable section nozzle including one or several movable parts capable of modifying the nozzle section and connected by a mechanical transmission chain to an actuator. The control device includes a system for regulating the power plant connected to a control member configured to control the actuator. The control device includes a single control member, an immobilization unit configured to immobilize all the movable parts which are deactivated only when the regulation system controls the positional change of the movable part or parts and a determination unit configured to determine the actual position of the movable part or parts.
摘要:
A control device for a gas turbine power plant of the type comprising a compressor, a combustion chamber supplied with air coming from the compressor and with fuel, a turbine supplied with combustion gases coming from the combustion chamber, and a nozzle which discharges the combustion gases coming from the turbine, said control device comprising means for metering the fuel flow to the combustion chamber and means for varying the crosssectional area of the nozzle, wherein the means for varying the cross-sectional area of the nozzle is controlled as a function of the fuel flow rate C delivered to the combustion chamber, the static air pressure P2 at exit from the compressor, and the static gas pressure Ps at the turbine exit, so that at least under certain conditions of operation, an output quantity defined by the expression c/( Beta Ps - Ps ), in which Beta designates a constant coefficient of reduction, has a desired predetermined value.
