Abstract

A thrust reverser is disclosed for an aircraft jet engine having a bypass duct enclosing a cowling with an outer cowling surface and a reverse thrust opening extending through the cowling. The thrust reverser has a thrust reverser door in the opening movable between a forward thrust position, in which the thrust reverser door covers the reverse thrust opening, and a reverse thrust position in which the thrust reverser door is moved within the thrust reverser opening, which is then uncovered, into a gas deflecting position at which position a portion of the door extends into the bypass duct. The thrust reverser door has an inner panel defining a part of the gas duct and an outer panel having an outer surface substantially flush with the outer cowling surface when the thrust reverser door is in the forward thrust position. The inner panel is sealed against the cowling. One or more discrete, narrow structural isolating connectors connect the outer panel to the inner panel in a manner that isolates the outer panel from radial deflections of the inner panel relative to the connectors that may result from gas pressure differential across the inner panel. Latches for securing the thrust r…
