A combustor assembly for a gas turbine engine defining an axial direction is provided. The combustor assembly generally includes a liner, an annular dome, and a deflector plate. The liner at least partially defines a combustion chamber. The annular dome defines a first cavity and has a plurality of impingement holes, and the deflector plate defines a conical surface and a flat surface, wherein a plurality of cooling holes are defined through the deflector plate. The annular dome and the deflector plate are positioned together to define a second cavity that is in fluid communication with the first cavity through the plurality of impingement holes. In addition, the second cavity is in fluid communication with the combustion chamber through the plurality of cooling holes.

An acoustic dampener comprises a first wall, orifice plate, and second wall. The first wall separates a first fluid source from a second fluid source. The first wall has a hole for allowing fluid communication between the first fluid source and a first cavity of the acoustic dampener. The office plate separates the first cavity of the acoustic dampener from a second cavity of the acoustic dampener. The second wall has a hole for allowing fluid communication between the first cavity of the acoustic dampener in the second cavity of the acoustic dampener. The second wall separates the second cavity of the acoustic dampener from the second fluid source. The second wall has a hole for allowing fluid communication between the second cavity of the acoustic dampener and the second fluid source. In one embodiment, the acoustic dampener is formed in a combustion chamber liner of a gas turbine engine.
