ABSTRACT:
A thrust reverser is disclosed for a turbojet engine having a cowling forming an outer boundary of a gas flow duct through which gases flow from a front to a rear, the cowling having at least one reverse thrust opening communicating with the gas flow duct and a thrust reverser door pivotally connected to the cowling so as to move between a forward thrust position wherein the thrust reverser door covers the reverse thrust opening, and a reverse thrust position wherein the reverse thrust opening is uncovered and the thrust reverser door directs at least a portion of the gases flowing through the duct through the reverse thrust opening. The thrust reverser also includes at least one panel having an inner surface, a first lateral side pivotally connected to the cowling so as to pivot about a panel pivot axis extending generally parallel to the gas flow direction through the duct and an actuating mechanism connected to a second lateral side of the panel so as to move the panel about the panel pivot axis between a first position in which the inner surface forms a portion of the outer boundary of the gas flow duct and a second position wherein the second lateral side is disposed within the gas flow duct. The actuating mechanism may include a mechanical linkage interconnecting the second lateral side of the panel to the thrust reverser door such that movement of the thrust reverser door between the forward and reverse thrust positions causes movement of the panel between the first and second positions.
