Abstract
A system of mounting segmented liner panels on the interior of an outer shell of a combustion chamber for a gas turbine engine. The system is effective to enable higher temperatures to be maintained thereby increasing engine efficiency while simultaneously guarding against structural failure. A plurality of concentrically disposed segmented liner panels are arranged in side by side circumferential relationship at successive axial locations. Each liner panel is fixed relative to the outer shell at one location proximate to a leading portion. In addition, each liner panel is restrained against radial movement relative to the outer shell, but relative axial and circumferential movement between the liner panel and outer shell is permitted. Mating spacer hooks and spring clip members are selectively engageable to mount a trailing portion of each liner panel to the outer shell. Lateral edges of adjacent liner panels are mutually configured to prevent escape of heat while accommodating circumferential expansion.
