METHOD OF CONTROL OF METERING NEEDLE OF GAS-TURBINE ENGINE FUEL FLOW GOVERNOR Russian patent published in 1995 - IPC

FIELD: automatic control systems of gas-turbine engines. SUBSTANCE: preset pressure is formed in proportion with deviation of parameter being regulated from preset magnitude. Fuel flow rate to controllable chamber of metering needle is changed in proportion with mismatching between preset pressure and pressure in controllable chamber of metering needle. Flow rate of fuel to controllable chamber of metering needle from chamber at preset pressure is formed additionally in proportion with difference between preset pressure and pressure in controllable chamber. EFFECT: enhanced efficiency. 1 dwg
