A thrust reverser is disclosed for a turbojet engine having a cowling forming an outer boundary of a gas flow duct through which pressurized gases flow, the cowling having a reverse thrust opening, in which the thrust reverser comprises a thrust reverser door assembly pivotally attached to the cowling so as to be movable between a forward thrust position in which the thrust reverser door assembly covers the reverse thrust opening through the cowling, and a reverse thrust position in which the thrust reverser door assembly directs at least a portion of the gases flowing through the gas flow duct through the reverse thrust cowling opening. The thrust reverser door has a front door having a first rear edge portion and a first inner surface forming a portion of the outer boundary of the gas flow duct when the thrust reverser door assembly is in the forward thrust position, and a rear door having a front edge portion pivotally attached to the rear edge portion of the front door and a second inner surface forming a portion of the outer boundary of the gas flow duct when the thrust reverser assembly is in the forward thrust position such that the resultant force of the pressurized gases acting on the first and second inner surfaces urge the thrust reverser door assembly toward its forward thrust position.

[ We claim:] [1.] A thrust reverser for a turbojet engine having a cowling forming an outer boundary of a gas flow duct through which pressurized gases flow from a front toward a rear, the cowling having at least one reverse thrust opening therethrough, the thrust reverser comprising:at least one thrust reverser door assembly pivotably attached to the cowling so as to be movable in a pivoting direction between a forward thrust position wherein the at least one thrust reverser door assembly covers the at least one reverse thrust opening to prevent gases in the duct from passing through the at least one reverse thrust opening, and a reverse thrust position wherein the at least one thrust reverser door assembly directs at least a portion of the gas flow in the duct through the reverse thrust opening, the at least one thrust reverser door assembly having a front door including a first front edge portion, a first rear edge portion and a first inner surface forming a portion of the outer boundary of the gas flow duct when the at least one thrust reverser door assembly is in the forward thrust position, and a rear door including a second front edge portion pivotally attached to the first rear edge portion of the front door such that the rear door pivots relative to the front door in a direction opposite to the pivoting direction of the at least one thrust reverser door assembly, a second rear edge portion which is free from attachment and a second inner surface forming a portion of the outer boundary of the gas flow duct when the at least one thrust reverser door assembly is in the forward thrust position such that the resultant force of the pressurized gases acting on the first and second inner surfaces urge the at least one thrust reverser door assembly toward the forward thrust position.
