    Abstract: An air swirler, a fuel and air admission assembly, and a staged combustor are disclosed.
    The air swirler (20) has a number of air passages (76, 78), and the air in the different passages can be made to swirl in different directions to improve mixing. The fuel and air assembly has inner and outer fuel ports, which allow fuel to be introduced to different regions of the assembly at the same time. The staged combustor may be equipped with the fuel and air admission assemblies incorporating the air swirlers for use in gas turbine engines, such as for example gas turbine engines powering aircraft having supersonic cruise capability.

    Abstract: A gas turbine engine combustor (20) has inboard and outboard walls (32,134). A forward bulkhead (36) extends between the walls and cooperates therewith to define a combustor interior volume. In longitudinal section, a first portion (54) of the combustor interior volume converges from fore to aft and a second portion (56), aft of the first portion (54) converges from fore to aft more gradually than the first portion (54).

    Abstract: An annular combustor (100) for a gas turbine has a combustion chamber having an interior volume that, in longitudinal section, includes a forward volume (V 1 ), an intermediate volume (V 2 ) and an aft volume (V 3 ). The forward volume (V 1 ) represents from about 30% to about 40% of the combustor interior volume, the intermediate volume (V 2 ) represents from about 10% to about 20% of the combustor interior volume, and the aft volume (V 3 ) represents from about 40% to about 60% of the combustor interior volume.

    Abstract: A combustor assembly (10) includes an inner and outer liner (16,18) defining a combustion chamber (22). The inner and outer liners (16,18) include a plurality of cooling holes (36) spaced a specified distance apart. The cooling holes (36) include first, second and third groups (44,46,48). The first group (44) of cooling holes (36) is the most densely spaced, followed by the second group (46) and then the third group (48). The first group (44) of cooling holes (36) begin upstream of a leading edge (50) of a large opening (50) and terminates downstream of the leading edge (50). The increased density of cooling holes (36) adjacent the large openings (38) provide increased cooling airflow in areas where cooling may be affected by local disturbances in cooling airflow.
