ABSTRACT:
The present invention relates to a thrust reverser for a turbojet engine having a cowling bounding a flow duct through which gases flow from the front of the cowling towards a rear of the cowling, the cowling having at least one reverse thrust opening communicating with the gas flow duct. The thrust reverser has a thrust reverser door pivotally mounted on the cowling so as to be movable between a forward and a thrust position, wherein the thrust reverser door covers the reverse thrust opening, and a reverse thrust position wherein the thrust reverser door uncovers the reverse thrust opening and directs at least a portion of the gases flowing through the gas flow duct outwardly through the reverse thrust opening. A vane having an air foil cross-sectional configuration is connected to the thrust reverser door and is located so as to be acted on by the gases passing through the gas flow duct when the thrust reverser door is adjacent to its forward thrust position, such that the vane exerts a force on the thrust reverser door urging it toward its forward thrust position.
