Abstract
The present invention relates to a thrust reverser for a turbojet engine having a cowling bounding a gas flow duct, the cowling having at least one reverse thrust opening communicating with the gas flow duct. The thrust reverser has a thrust reverser door with forward and rear portions, a first opening in the forward portion, a second opening in the rear portion and a passage communicating with the first and second openings. The thrust reverser door is pivotally attached to the cowling adjacent to the rear portion of the door so as to be movable between a forward thrust position, wherein the thrust reverser door covers the at least one reverse thrust opening in the cowling such that an inner surface of the thrust reverser door forms a portion of the boundary of the gas flow duct and wherein the first opening is blocked by the cowling, and a reverse thrust position wherein the forward portion of the thrust reverser door extends into the gas flow duct to direct at least a portion of the gas in the gas flow duct into the passage so as to generate a reverse thrust force. A panel is located so as to cover the second opening in the thrust reverser door when the thrust reverser door is in the forward thrust position and to uncover the second opening when the door is in the reverse thrust position.
