A thrust reverser is disclosed for a turbofan type turbojet engine assembly with a cowling having an inner cowling surface forming an outer boundary of a gas flow duct, and an outer cowling surface spaced from the inner cowling surface, the inner and outer cowling surfaces joining at a rearmost edge of the cowling, the thrust reverser having a thrust reverser baffle with an outer baffle surface and an inner baffle surface, a forward linkrod pivotally connected to a forward portion of a thrust reverser baffle and to the cowling, and a rear linkrod pivotally connected to the thrust reverser baffle and to the cowling. The thrust reverser baffle is movable between a forward thrust position wherein the outer baffle surface is substantially flush with the outer cowling surface, a forward portion of the thrust reverser baffle covering an inner rear cowling portion having the inner cowling surface, and a reverse thrust position in which the reverse thrust baffle is disposed rearwardly of the rearmost cowling edge so as to redirect gases flowing through the gas flow duct. When in the forward thrust position, the forward and rear linkrods are totally enclosed between the spaced apart inner and outer cowling surfaces.

[ We claim:] [1.] A thrust reverser for a turbojet engine assembly with a cowling having an inner cowling surface forming an outer boundary of a gas flow duct, and an outer cowling surface spaced from the inner cowling surface, the inner and outer cowling surfaces each having a rear edge with the rear edge of the inner cowling surface extending more rearwardly than the rear edge of the outer cowling surface to form an inner rear cowling portion, the cowling having at least one longitudinal beam extending rearwardly beyond at least the rear edge of the outer cowling surface, the cowling having a rearmost edge, the thrust reverser comprising:a) at least one thrust reverser baffle having an outer baffle surface and an inner baffle surface;b) at least one forward linkrod pivotally connected to a forward portion of the at least one thrust reverser baffle and to the cowling;c) at least one rear linkrod pivotally connected to the at least one thrust reverser baffle and to the cowling, the at least one rear linkrod being located rearwardly of the at least one forward linkrod; and,d) a linear actuator having an extendable and retractable rod which is connected to one of the at least one forward and rear linkrods; whereby the at least one thrust reverser baffle is movable, by movement of the rod of the linear actuator, between a forward thrust position, in which the outer baffle surface is substantially flush with the outer cowling surface and at least a forward portion of the at least one thrust reverser baffle covers the inner rear cowling portion with the at least one forward and rear linkrods totally enclosed between the inner rear cowling portion and the outer surface of the at least one thrust reverser baffle and between the at least one longitudinal beam and the at least one thrust reverser baffle, and a reverse thrust position, in which the at least one reverse thrust baffle is disposed rearwardly of the rearmost cowling edge so as to redirect gases flowing through the gas flow duct.
