METHOD OF GAS-TURBINE ENGINE CONTROL Russian patent published in 2017 - IPC F02C9/00 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in electronic-hydro-mechanical systems of gas-turbine engine automatic control. The control signals of the electronic control, hydromechanical controller and selector signals are then converted into pneumatic signals, the control signals of the hydromechanical controller are cut off by the selector signal and the logic jet circuit cut off the control signal from the hydromechanical controller by the selector, and control signals of electronic control are send to executive mechanism, and the engine control is carried out, in case of electronic control failure the control signals of electronic control are cut off by the selector signal and logic jet circuit, and the control signals of the hydromechanical controller are supplied to the same executive mechanism, and the engine control is carried out.

EFFECT: providing optimal control of the gas-turbine engine in all operation modes.
