Abstract
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.
