Abstract:
A gas flow guide for an aircraft jet engine thrust reverser having a thrust reverser door movably connected to an engine cowling so as to move between forward and reverse thrust positions, the cowling having a reverse thrust opening bounded by a forward edge having a deflector, and by opposite lateral side edges, an inner surface of the cowling forming an outer boundary of a gas flow duct, a forward inner surface of the thrust reverser door tapering toward an outer surface of the thrust reverser door such that a cavity is defined between the forward inner surface and the outer boundary of the gas flow duct, the cavity opening into the gas flow duct, the gas flow guide comprising:a movable panel which is movable with the thrust reverser door between a forward thrust position wherein the panel covers the cavity and a reverse thrust position wherein at least a portion of the panel is moved into the gas flow duct; andat least one guide vane located rearwardly of the forward edge deflector and in the cavity when the thrust reverser door is in the forward thrust position, the at least one guide vane being arranged to guide the gas passing through the reverse thrust opening when the thrust reverser door is in the reverse thrust position, the at least one guide vane comprising a stop device which contacts the panel when the panel is in the forward thrust position.
