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.

In a combustion chamber for a gas turbine engine, the improvement comprising: a generally cylindrically configured outer shell having a longitudinal axis and a plurality of annular lands lying in planes transverse to said axis and at spaced locations along said axis; a plurality of axially spaced concentrically disposed segmented liner panels arranged in side by side circumferential relationship, each of said liner panels having a leading portion, a trailing portion, and opposed lateral portions extending, respectively, between said leading portion and said trailing portion, first mounting means for fixedly attaching each of said liner panels to an associated one of said annular lands at a first location proximate to said leading portion such that said first location of said liner panel is thereby denied axial, radial, and circumferential movement relative to said outer shell; second mounting means for attaching each of said liner panels to said associated annular land at a second location distant from said first location but proximate to said leading portion such that radial, axial and circumferential movement of said liner panel relative to said outer shell is permitted; and third mounting means for attaching each of said liner panels to said outer shell at a third location proximate to said trailing portion such that said third location of said liner panel is thereby held at a spaced distance away from said outer shell and restrained against radial movement relative to said outer shell while axial and circumferential movement of said liner panel relative to said outer shell are permitted.
