AUTOMATIC CONTROL SYSTEM FOR GAS-TURBINE ENGINE Russian patent published in 1994 - IPC

Abstract SU 1642812 A1

FIELD: aircraft engineering. SUBSTANCE: main or doubling digital electronic controllers 1,2 provided with built-in control units 3,4 generate control signals for actuator 10. If electronics are failed stand-by hydromechanical controller 9 is set in operation. Switching of controlling is performed by switches 7,8 and logical elements 11,12. Unit 14,18 and also unit 15,19 of mathematical models of the engine and actuator are used for detecting faults of engine pickups and actuator 10. The system detects and parries failures of electronics among which are the failures of the engine pickups and hydromechanical part. EFFECT: enhanced reliability. 1 dwg
