Abstract: The present disclosure is directed to a combustor assembly for a gas turbine engine. The combustor assembly defines a combustion chamber and a diffuser cavity disposed upstream of the combustion chamber. The combustor assembly includes an acoustic damper that includes an aft wall adjacent to the combustion chamber and a forward wall adjacent to the diffuser cavity. A connecting wall is extended at least along the longitudinal direction and coupled to the aft wall and the forward wall. A damper cavity is defined by the connecting wall, the aft wall, and the forward wall.
