FIELD: engines and pumps.
SUBSTANCE: air pressure is measured at compressor outlet, by values of air temperature at engine inlet and compressor rotor rotation frequency control signal of specified compressor rotor rotation frequency. Note that there is additional specified value of compression degree and specified compressor air consumption ratio and specified value of compression degree and specified compressor air consumption ratio depending upon air temperature at engine inlet. The values are summed up and control signal is supplied to comparing element second input, the first input receives the signal of current value of air compression degree in compressor and air consumption ratio. There formed is a signal of difference between program and current values of air compression degree in compressor and air consumption ratio and obtained control signal is supplied to servo mechanism of compressor guide vanes drive.
EFFECT: maximum meaning of coefficient efficiency of the compressor and its gas and dynamic stability.
