Abstract:
A gas flow guide for an aircraft jet engine thrust reverser having a thrust reverser door movably connected to a 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 when the thrust reverser door is in the forward thrust position, the gas flow guide comprising at least one stationary 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 having a cross-sectional configuration of a teardrop the at least one guide vane being stationary at least with respect to the cowling and arranged to guide the gas passing through the reverse thrust opening when the thrust reverser door is in the reverse thrust position.
