Patent ID: 8322146

Claim:
A transition duct assembly comprising: a panel assembly; a generally rectangular aft frame fixed to an exit end of the panel assembly, the aft frame having a plurality of retention lugs located on the aft frame; an aft mounting bracket coupled to one or more of the retention lugs; and, a forward mounting bracket positioned adjacent an inlet of the panel assembly; inner and outer bulkhead assemblies having: a first inner bulkhead and a first outer bulkhead, each of the first bulkheads having a plurality of first through holes; a second inner bulkhead and a second outer bulkhead, each of the second bulkheads having a plurality of second through holes, the second outer bulkhead also having a plurality of towers extending radially outward from the second outer bulkhead, the towers positioned towards ends of the second outer bulkhead end, each tower having a through hole oriented generally perpendicular to the plurality of second through holes and each tower configured such that it is received in a channel in the aft mounting bracket having a generally U-shaped curved radius; a plurality of bushings, each bushing having an axial length, a circumferential length, a radial width, and a third through hole; and, a plurality of fasteners for securing the bulkheads and bushings to the retention lugs of the aft frame such that one of the bushings is located within slots of outermost retention lugs and the fasteners for each of the bulkhead assemblies passes through the first and second through holes of the first and second bulkheads and through slots of the retention lugs; wherein the generally U-shaped curved radius of each channel permits movement of the transition duct assembly in at least a transverse direction about the radial axis.
