Abstract

The invention relates to a thrust reverser for a jet engine of an aircraft, which comprises two symmetrical doors pivotally mounted about an axis which is transverse and substantially diametrical to the jet of said engine and which is disposed downstream of the jet exhaust pipe thereof, the doors each being pivoted due to two diametrically opposite hinges and occupying a folded or stowed position in which they form part of the fairing of the engine or fuselage of the aircraft, or an unfolded or opened out position in which they are disposed transversely to the jet, while at least one longitudinal jack is provided at the level of a hinge, for the simultaneous control of the doors via connecting rods. According to the invention, this reverser is characterized, on the one hand, in that the jack comprises two aligned pistons rigidly connected by a common intermediate piston rod, each piston being housed in a corresponding cylinder and the two cylinders being rigidly connected together, and, on the other hand, in that the connecting rods for controlling the doors are pivoted on the intermediate piston rod. The invention finds particular application to the braking of aircraft.
