METHOD OF MECHANIZATION CONTROL OF GAS TURBINE ENGINE COMPRESSOR Russian patent published in 2017 - IPC F04D27/00 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in electronic-hydromechanical and hydromechanical systems of automatic control of GTE. The summary of the invention consists in simplifying the implementation of the method for controlling the mechanization of a GTE compressor based on the rotation speed of an engine turbocompressor (TC) by determining the reduced rotation speed of the TC over the engine's in-engine parameters without measuring the air temperature at the engine inlet. This is achieved by the fact that the engine TC rotation speed, found from the reduced throttle characteristic of the engine using the fuel consumption in the engine, given only by the air pressure at the engine inlet, is corrected by an amount proportional to the deviation of this speed from the measured TC rotation speed. The correction factor is determined by the nature of the reduced throttle characteristic and the operating mode of the engine.

EFFECT: simplification of technical devices for controlling the mechanization of a gas turbine engine compressor and reducing the cost and reliability of a gas turbine engine.
