Abstract
A thrust reverser for a turbojet engine is disclosed having a first thrust reverser door pivotally attached to the engine cowling so as to be movable between a forward thrust position and a reverse thrust position, the first thrust reverser door having a first inner surface forming a portion of the outer boundary of the gas flow duct when the first thrust reverser door is in the forward thrust position, a first outer surface and a rear portion which extends into the gas flow duct when the first thrust reverser door is in the reverse thrust position so as to direct at least a portion of the gases passing through the duct outwardly through an opening in the cowling, and a second thrust reverser door pivotally connected to the cowling so as to also be movable between a forward thrust position and a reverse thrust position, the second thrust reverser door having a second outer surface which, with the first inner surface of the first thrust reverser door, form opposite boundaries of a passage directing the gases in a reverse thrust direction when the first and second thrust reverser doors are in their reverse thrust positions, and a second inner surface to direct air flowing over the outer cowling surface away from the reverse thrust gas flow.
