FIELD: engines and pumps.
SUBSTANCE: invention is related to the field of aviation propulsion engineering and may be used in electronic-hydromechanical systems (automatic control systems - ACS) for gas turbine engine (GTE) automatic control. Substance of invention consists in the fact hat frequency of engine rotor rotation is additionally measured and controlled, and if rotational frequency exceeds previously set value, command is generated, and control action of electronic control is blocked with the help of selector, and control action of hydromechanical control is sent to final control element, and engine is controlled from hydromechanical control.
EFFECT: higher reliability of ACS operation and, accordingly, higher reliability of GTE and safety of aircraft.
