    • A gas turbine engine has a compressor, a fan for delivering air into the compressor and into a bypass duct, a combustion section and a turbine section. A control for the gas turbine engine is programmed to change a fueling level and position at least one effector that may be moved to unique positions in a coordinated fashion upon receipt of a command to change thrust. The thrust provided by the engine is changed without a reduction in an airflow stability margin compared to a thrust change commanded only by a fueling change. Some aspects of the positioning are transitory.
    • 燃气涡轮发动机具有压缩机,用于将空气输送到压缩机中并进入旁通管道,燃烧部分和涡轮部分的风扇。 用于燃气涡轮发动机的控制被编程为改变燃料供给水平并且定位至少一个效应器,其可以在接收到改变推力的命令时以协调的方式移动到独特的位置。 发动机提供的推力与仅由加油变化指令的推力变化相比,改变了气流稳定性裕度的降低。 定位的一些方面是暂时性的。

    • 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.
