METHOD OF CONTROL OVER GAS TURBINE ENGINE COMPRESSOR DISTRIBUTORS

摘要

FIELD: engines and pumps.SUBSTANCE: proposed method consists in using engine inlet air temperature and compressor rotor rpm to generate control signal for actual reduced compressor rotor rpm. Magnitude of preset reduced compressor rotor rpm is set to compare it to generated actual reduced compressor rotor rpm. Note here that in case actual reduced compressor rotor rpm is smaller than preset one, compressor distributors are controlled by flow rate of air passing through compressor. Note here that in case actual reduced compressor rotor rpm exceeds preset one, compressor distributors are controlled by air compression ratio.EFFECT: maximum efficiency and gas-dynamic stability.1 dwg
