  • Patent number: 4438626
    Abstract: A scroll-wound metallic cushioning bushing in a bore in a ceramic part permits pin-type connection between the ceramic part and a surrounding metal structure while cushioning against vibration and differential thermal loading which may otherwise destroy the relatively brittle ceramic material. In one embodiment, a scroll-wound cushioning bushing is employed in a trip baffle in a flameholder of an afterburner diffuser section wherein the pins holding the trip step in place are surrounded by the ceramic material and thus protected from the extreme heat found in a flameholder. In another embodiment of the invention, a large ceramic part is supported on a plurality of pins each passing through a cushioned bushing assembly which permits not only radial relative motion of pins and ceramic part, but also permits limited axial displacement and twisting.
