GAS-TURBINE ENGINE STARTING FUEL FEED CONTROL SYSTEM

摘要

FIELD: mechanical engineering; fuel feed control at starting. SUBSTANCE: system has starting automatic device, fuel metering needle and fuel pump. Temperature pickups with ferromagnets and electronic control unit are installed before turbine. Electronic control unit has input and output signal differentiators, divider, logic element - sign discriminator and reversing element electrically coupled with temperature pickups and starting automatic device. EFFECT: enhanced reliability of starting of gas-turbine engine by maintaining maximum possible temperature of gas before turbine. 1 dwg
