FIELD: reheated turbojet engines with swivel jet propulsion nozzle and control system mounted on highly-maneuverable multi-function fighter aeroplanes. SUBSTANCE: engine includes after- burner and swivel jet propulsion nozzle with hydraulic system of actuator. Used as working medium in actuator hydraulic system is fuel; to this end, hydraulic system is brought into communication with fuel system of engine through electrohydraulic regulator-converter. Control members of electrohydraulic regulator-converter are electrically connected with swivel nozzle remote control system and are hydraulically connected with forward and back stroke chambers of nozzle turn actuator cylinders. Fuel pump is provided with solenoid-operated valve electrically connected with nozzle turn remote control system. Control members of electrohydraulic regulator and body of swivel nozzle are kinematically interconnected by means of mechanical back coupling. EFFECT: enhanced reliability of aircraft hydraulic control system and swivel nozzle actuator. 2 cl, 1 dwg
