摘要： A combustor for a turbine engine includes a hot wall and a cold wall forming a dual walled liner and a liner cavity with the hot wall. The cold wall defines a plurality of impingement cooling holes configured to deliver an impingement cooling flow. A first downstream end terminates the hot wall and is configured to receive the impingement cooling flow from the plurality of impingement cooling holes, and a second downstream end terminates the cold wall and is longer in a generally downstream direction than the first downstream end. A combustion chamber is formed with the dual walled liner and the liner and faces an opposite side of the hot wall relative to the combustion chamber. The combustion chamber has a longitudinal axis and is configured to receive an air-fuel mixture in the generally downstream direction along the longitudinal axis.
