Abstract
A high temperature mounting system useful, for example for ceramic composite flameholders in a gas turbine engine reheat system uses dovetail clamping. A flameholder carries a dovetail projection which is clamped against a further ceramic, intermediate member by wedge blocks on opposite sides of the dovetail. The intermediate member has raised edges with angled faces opposite the dovetail projection against which the wedge blocks bear. The assembly is clamped to a metal support or flange by clamp bolts which pass through each of the wedge blocks and the intermediate member. The included angle of the contact faces is determined by principles of DAZE geometry to keep the bolts from loosening due to differential thermal expansion. Each wedge block is clamped by single bolt and relative expansion between the bolts is absorbed by bolt bending or nut sliding.
