Abstract
A combustor adapted for use in a gas turbine engine is disclosed. The combustor includes a metallic shell forming a cavity and a ceramic liner arranged in the cavity of the metallic shell. The ceramic liner defines a combustion chamber in which fuel is burned during operation of a gas turbine engine. The ceramic liner includes a plurality of ceramic tiles mounted to the metallic shell and arranged to shield the metallic shell from heat generated in the combustion chamber.
Claims20
A combustor for use in a gas turbine engine, the combustor comprising
- an annular metallic shell forming an annular cavity, and
- an annular liner arranged in the annular cavity of the annular metallic shell and defining an annular combustion chamber, the annular liner including a plurality of ceramic tiles arranged to shield the annular metallic shell from combustion in the combustion chamber,
- wherein each ceramic tile is secured to the metallic shell by a plurality of securement fasteners, each securement fastener extends through corresponding securement slots formed in the ceramic tiles, and each securement slot is elongated to allow growth of the ceramic tiles during high-temperature operation of the combustor.
A combustor for use in a gas turbine engine, the combustor comprising
- an annular metallic shell forming an annular cavity, the annular metallic shell including an outer shell member and an inner shell member nested concentrically inside the outer shell member, and
- an annular liner arranged in the annular cavity of the annular metallic shell and defining an annular combustion chamber, the annular liner including a plurality of ceramic tiles arranged to shield the annular metallic shell from combustion in the combustion chamber,
- wherein one of the outer shell member and the inner shell member of the annular metallic shell includes a wall and a plurality of dimples extending from the wall toward the annular liner and each of the plurality of ceramic tiles is formed to include a hollow sized and arranged to receive at least a portion of one of the dimples included in the annular metallic shell.
A method of assembling a combustor, the method comprising
- coupling a first ceramic tile to a shell of the combustor via a first fastener extending through the first ceramic tile, and
- coupling a second ceramic tile to the shell via a second fastener extending through the second ceramic tile,
- wherein the second ceramic tile is coupled to the shell so that a portion of the second ceramic tile is arranged between the first fastener and a combustion chamber defined by the first and second ceramic tiles so that the first fastener is shielded from heat generated in the combustion chamber during operation of the combustor.
