CONTROL METHOD OF ANTI-ICING SYSTEM OF BYPASS TURBOFAN ENGINE Russian patent published in 2020 - IPC B64D15/04 B64D15/22 F02C6/08 

FIELD: aviation.

SUBSTANCE: invention relates to anti-icing systems of aircrafts, particularly, to control method of anti-icing system of bypass turbofan engine (BTFE). Method of controlling an anti-icing system BTFE consists in that in flight using an engine-mounted sensor, measuring external parameters of flight conditions, on the change of which signals are generated to open the gate of the collector for extraction of hot air from the high-pressure compressor and to the sensors for measuring the rotation speed of the rotor of the fan and the rotor speed of the gas generator, determining the ratio of rotation frequencies and calculating the value of rotors sliding, by the change of which the icing nature and location is determined, then, signal is generated to electronic control unit of control device, which directs hot air flow to certain icing point via appropriate channel.

EFFECT: development of control method for anti-icing system of BTFE, which provides higher efficiency of engine due to reduced amount of extracted working medium (hot air).
