Gas turbine engine operation

FIELD: engines and pumps. SUBSTANCE: gas pressure is measured at compressor outlet, pressure and rotor speed are used as a comparison parameter, measurements are performed at a constant turbine outlet temperature at intervals of 0.2…0.5 s, measurement comparison and threshold determination of deviations are made by at least two preceding and two subsequent actual parameter values, the engine stop is carried out at 0.2…0.5 per cent decrease in rotor speed and at 1.0…1.5 per cent decrease in compressor discharge pressure. EFFECT: prevention of the destruction of gas-air engine flow duct caused by various factors during the gas turbine engine operation at the ground-based installation. 1 dwg
