Classification: CPC F | IPC F

Claim 14:
15. A gas turbine engine including an outer casing, the gas turbine engine defining an axial direction and a radial direction, the gas turbine engine comprising:
a compressor section;
a turbine section mechanically coupled to the compressor section through a shaft; and, a combustor assembly disposed between the compressor section and the turbine section, the combustor assembly comprising:
an outer liner at least partially defining a combustion chamber extending between an aft end and a forward end generally along the axial direction within the outer casing, the outer liner including an inner surface facing the combustion chamber and an outer surface facing away from the combustion chamber toward the outer casing; and
a radial damper assembly disposed between the outer casing and the outer surface of the outer liner at a plurality of circumferential points, the radial damper assembly including at least one spring enclosing a rigid conduit disposed at one of the plurality of circumferential points, the at least one spring extending through an entire radial thickness of the outer casing, wherein the radial damper assembly is configured to tune oscillations at each of the plurality of circumferential points,
wherein the radial damper assembly includes a radial pushrod disposed in engagement with the outer surface of the outer liner to damp oscillations in the radial direction.
