CONTROL METHOD OF TWO-SHAFT GAS TURBINE ENGINE WITH ADJUSTABLE GUIDE VANES OF COMPRESSOR AND FAN Russian patent published in 2019 - IPC F02C9/00 F04D27/00 

FIELD: engines and pumps.

SUBSTANCE: invention relates to aircraft engine building, namely, to control of two-shaft gas turbine engine with adjustable guide vanes. Method of control of two-shaft gas turbine engine with adjustable guide vanes of compressor and fan includes control of low and high pressure rotors rotation speed by changing fuel flow to main combustion chamber, regulation of guiding devices position by signal from position sensor of guiding devices of corresponding rotor. At the same time prior to operation of the engine, setting the rotor rpm ratio for each engine operating mode, further in the course of engine operation in case of absence of signal from position sensor of guide vanes of one of rotors, rotation frequency of this rotor is controlled by action on speed of its guiding devices movement proceeding from previously set ratio of rotor rotational speeds.

EFFECT: higher reliability of engine control system without additional redundancy of guide vanes position sensors.
