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 the material mounted by means of a slideable friction 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 liner panels in the circumferential, axial, and radial directions with respect to the frame as well as circumferentially with respect to other liner panels. The individual liner panels may be easily removed for repair or replacement without disassembling the frame and associated components. For the purpose of cooling, a cooling fluid is passed into a plenum to cool the radially outward side of the panels by convection. Means are also provided for directing the same fluid from the plenum to the liner inner surfaces in a cooling film.
