Abstract: The invention concerns a system for controlling the flaps of a turbine engine nozzle. High-pressure air P4 is bled from the compressor of the turbine engine to feed a compressed-air engine. The shaft of the engine rotates a constant-capacity displacement pump which sends hydraulic liquid into a jack controlling the flap or flaps of the nozzle. The invention is applicable to the control of all movable flaps of turbine engine nozzles.

Abstract: The invention relates to a deceleration limiter for a turbine engine. Through a rotary cam and a compressed spring, the throttle lever acts on a regulator for the fuel injector, for instance on the beam of a tachometric scale. According to the invention, the piston of a hydraulic damper and a push rod are interposed between the spring and the periphery of the cam. The chamber is connected to a source of ambient fluid under pressure p, which also acts on the other side of, through a damper valve which enables only the fluid to penetrate into, and by a diaphragm. The invention applies particularly to turbojet regulators to limit the magnitude and speed of development of the system parameters controlling the operation of the turbine engine following an abrupt deceleration command initiated by the pilot.
