Differential expansion contraction structural interconnection system

摘要

A thermally compliant structural interconnection of a support structure and working material components provided by surfaces of the working material components being engaged by surfaces of the support structure. Dissimilar materials or components that are at different temperatures may be interconnected by support structure projections engaging recesses in the components. By providing the recesses in at least two axially displaced rows, the projections expansion or contraction relative to the recesses is compensated for thereby maintaining the projections in engagement with the surfaces of the recesses. Accordingly, relative displacements of the members axes are minimized and distortions circumvented.
