CONTROL METHOD OF POSITION OF GUIDE VANES OF COMPRESSOR OF GAS TURBINE ENGINE

摘要

FIELD: engines and pumps. ^ SUBSTANCE: air temperature and pressure at the engine inlet and compressor outlet, as well as rotor rotation speed of compressor is measured; as per air temperature values at the engine inlet and rotor rotation speed of compressor the control signal of the specified rotor rotation speed of compressor is shaped; at that, as per values of the specified rotor rotation speed of compressor and air temperature at the engine inlet the programme values of the specified air flow rate of compressor are also shaped; the obtained programme values are added and the obtained programme control signal of the specified compressor air flow is compared to actual value of the specified air flow rate through compressor; difference signal of programme and actual values, air flow rate is shaped; the obtained control signal is supplied to actuator of control drive of guide vanes of compressor. ^ EFFECT: maintaining maximum efficiency value of compressor and its gas dynamic stability margins. ^ 1 dwg
