A turbojet-engine thrust reverser comprises a displaceable sub-assembly including two internal clamshells (12) mounted on stationary pivots (18) of a stationary structure (1) and an annular, axially displaceable structure (11). The displaceable structure forms the external, downstream part (13) of a cowling. In the forward-thrust mode, the displaceable structure forms a downstream portion (15) of a radial outer wall of the flow path and forms the entire trailing edge by covering the clamshells (12) such that the clamshells form part of the radial outer wall of the flow path.

Turbojet-engine thrust reverser with internal clamshells

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 reverser doors are aligned with the isolating connector(s) longitudinally.

Thrust reverser door with isolated outer panel

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.
