ABSTRACT:
A combustion chamber, such as for a gas turbine engine, includes a protective liner comprised of a plurality of arcuate panels attached to the combustion chamber wall by means of hook-like hangers or lugs integral with and extending radially from the panels through slots in the combustion chamber wall. The lugs hang from retaining strips disposed across a portion of the slots through which the hangers pass. The strips prevent the lugs from being withdrawn from the slots, thereby, positioning the panels radially. Axial and circumferential positioning of the panels is accomplished by means of a close fit between the hangers, slots, and retaining strips. The free floating or nonrigid manner in which the liner panels are attached to the combustion chamber prevents undue stresses from developing in the combustion chamber wall due to the differential thermal growth rates of the combustion chamber wall and the liner panels during engine operation.
