ABSTRACT:
In order to reduce weight while also minimizing volume and pressure drop in a combustor assembly (18) for a turbine engine, the combustor assembly (18) includes an annular combustion chamber having a combustion space (20) defined entirely be an annular combustor case (22). The combustion chamber (18) is adapted to combust fuel and air in the combustion space (20) to generate gases of combustion. It has a combustor outlet (26) leading to a turbine nozzle (16). The outlet (26) is defined by a pair of turbine shrouds (28, 30). It also has a combustor inlet (32) leading to the combustion space (20). The combustor inlet (32) is defined by the combustor case (22) and one of the turbine shrouds (28). The combustion chamber (18) is adapted to receive injected air at the combustor inlet (32) in a manner creating a generally annular air flow in the combustion chamber (18) about the combustor case (22). In addition, the combustor assembly (18 ) is such that fuel in injected from a source into the combustion chamber (18) in the form of a fuel film (38) at the combustor inlet (32) radially inwardly of and directed parallel to the injected air which is preferably swirled to assist in atomizing the fuel film (38).
