Abstract:
1. An apparatus for use with a propulsion system, the apparatus comprising: an attachment frame to be coupled to a first end of a first structure having a first coefficient of thermal expansion, the attachment frame including a frame ring with a first plurality of spaced-apart fastener openings extending through the frame ring, the attachment frame further including a frame flange extending from the frame ring with a second plurality of spaced-apart fastener openings extending through the frame flange, the first and second plurality of spaced-apart openings to receive fasteners to couple the attachment frame to the first structure; a plurality of fastener rings spaced apart from the attachment frame; and a plurality of frame ribs extending between the attachment frame and the fastener rings, wherein each frame rib includes members which converge to a respective one of the fastener rings, each of the fastener rings having a fastener ring opening extending through each fastener ring, each fastener ring to couple to a respective opening adjacent a second end of the second structure having a second coefficient of thermal expansion that is different than the first coefficient of thermal expansion, the coupling to facilitate expansion between the first and second structures in one or more of radial or axial directions with substantially reduced application of thermally induced stresses to the second structure.
