Abstract
Abstract A combustion chamber for use in gas turbine engines is provided with a liner formed of a high temperature material. The liner includes a plurality of panels of material mounted by means of a slideable, frictional mounting arrangement upon a high strength structural frame. As a result of this mounting arrangement, the liner is substantially isolated from structural forces associated with the combustion chamber, while the frame is substantially isolated from thermal stresses associated with the liner. Means are provided for positioning and securing individual panel members axially relative to the frame. The panels may be continuous annular bodies, or may be circumferentially segmented. In the latter case, means are provided for mounting individual panels in a slideable, frictional cooperation with laterally adjacent panels, as well as for sealing the abutting junctions. The individual liner panels may be easily removed for repair or replacement without disassembling the frame and associated components.
