Abstract

711, 846. Gas turbine jet propulsion plant. SOC. RATEAU, and ANXIONNAZ, R. Nov. 7, 1950 [Jan. 26, 1950], No. 27212/50. Class 110(3) A control device for an aircraft gas turbine propulsion unit having an air compressor, comprises a governor responsive to the rotational speed of the unit and detecting means responsive to the air temperature or pressure at the inlet of the compressor which are connected through conjugate transmission means to means for adjusting the velocity of flow through the unit. The flow adjusting means described are the fuel supply and a variable area propulsion jet. The purpose is to prevent a given Mach. No. in the unit being exceeded. In the jet propulsion plant shown the fuel supply to the combustion chamber 3 is controlled by a by-pass valve 18 which is actuated by a rocking lever 16. The lever 16 is connected, at the end opposite to the valve 18, to a spring 15 the loading of which is determined by the setting of a pilot's lever 14 and a servomotor 11. The servomotor is operated by a bimetallic strip 7 located in the air intake to the compressor 2 so that an increase in temperature of the inlet air increases the loading of the spring. A speed governor 17 driven by the gas turbine is connected to an intermediate point of the lever 16 so that the loading of the governor balances that of the spring 15. For each position of the lever 14 there is. therefore, a rotational speed of the turbine corresponding to each valve of the inlet temperature. In a modification, the bi-metallic strip 7 is replaced by a barometric device responsive to the ram pressure. In another modification, the bimetallic strip 7 and speed governor 17 are used to control a variable area jet propulsion nozzle. It is stated that both the fuel supply and the area of the jet propulsion nozzle may be operated simultaneously. The invention is also shown applied to ducted fan and propeller turbine engines. Specifications 650,661 and 650,710 are referred to.
