Abstract

A thrust reverser is disclosed for a turbojet engine having a cowling with an inner cowling surface forming an outer boundary of a gas flow duct through which gases flow from a front towards a rear portion, the cowling having an outer cowling surface and at least one reverse thrust opening communicating with the gas flow duct. The thrust reverser has a thrust reverser door pivotally connected to the cowling so as to move between a forward thrust position and a reverse thrust position, the thrust reverser door having front and rear edge portions, an outer door surface and an inner door surface with at least one of the outer and inner door surfaces being flush with at least one of the corresponding outer and inner cowling surfaces when the thrust reverser door is in the forward thrust position. The thrust reverser also has at least one thrust reversing panel having an outer panel surface and an inner panel surface mounted on the thrust reverser door so as to move along a linear path of movement relative to the thrust reverser door as the thrust reverser door moves between the forward and thrust portions. When the thrust reverser door is in the forward thrust position, the inner panel…
