ABSTRACT:
In an axial flow gas turbine engine, a shear wire flange joint for an aft centerbody having an outer ring flange, and an inner ring flange that are held close together and a locking member interposed therebetween is provided. The flanges are specially configured to achieve positional alignment and a uniformly shaped groove is machined into the surface of both the inner and the outer ring flange. The circumferential grooves are aligned to form a space between the flanges. A wire is inserted into the space through a window provided in the outer ring flange. The wire locks the inner and the outer ring flange together by preventing axial movement of the inner and outer ring flanges relative to one another.
