GAS-TURBINE ENGINE CONTROL METHOD Russian patent published in 2007 - IPC F02C9/00 

FIELD: aircraft industry; engines.

SUBSTANCE: invention can be used in automatic control electronic hydromechanical systems of gas-turbine engines. According to invention, with electronic governor in good repair, control action of hydromechanical governor is adjusted to make it equal to control action of electronic governor, and in case of failure of electronic governor, control action of hydromechanical governor is adjusted to provided its changing steplessly within preset time whose value is adjusted, depending on characteristics of said engine, from value equal to control action of electronic governor at change over of selector to value formed by hydromechanical governor depending on position engine control lever and values of parameters of automatic control system according to laws of control implemented in hydrotechnical governor.

EFFECT: improved reliability of engine in operation owing to coordinated operation of electronic and hydromechanical governors with provision stepless transfer to control of engine by hydromechanical governor at failure of electronic governor.
