    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 (12) includes a convergent segment (34) followed by a divergent segment (36) to advantageously improve combustion. The combustor assembly includes a first segment (34) beginning at a forward end (24) that transitions to a second segment (36) past a transition segment (58) in a direction along a combustor axis (22) toward an aft end (26). The reduction in cross-sectional area within the first segment (34) provides desirable fuel and air mixing properties. The convergent first segment (34) in combination with the divergent second segment (36) decreases residence time of fuel-air mixture within the combustor chamber that decreases production of undesirable emissions from the combustor assembly.

    Abstract: A swirler (50;80) for fuel injection in a gas turbine engine (10) includes a frustoconical swirler body (51). First and a second air flow paths (52,54;82) direct air in generally opposed circumferential directions into the swirler (50;80). These air paths intermix and create turbulence. As this turbulence encounters fuel droplets, the fuel is atomized, and uniformly distributed within the air flow. A shear layer is created adjacent an inner surface of the swirler body (51). In a separate feature, a third air flow path (56;84) is directed into the air.

    Abstract: A combustor assembly includes an inner and an outer liner defining a combustion chamber. The inner and outer liner includes a plurality of cooling holes that are spaced a specified distance apart. The cooling holes include a specified inclination angle (54) and circumferential angle (56). A first group (58) of cooling holes is spaced apart according to a uniform geometric pattern and density. A second group (62; 68; 72) disposed between the first group (58) and some structural feature (32; 38; 40) within the liner assembly is disposed at a non-uniform pattern and a hole density equal to the density of the first group of cooling holes. The non-uniform cooling hole arrangement increases cooling flow effectiveness to accommodate local disturbances and thermal properties.

    Abstract: A combustor for a turbine engine includes an outer liner (34) having a row of circumferentially distributed outer combustion air holes and an inner liner (32) circumscribed by the outer liner (34) and having a row of circumferentially distributed inner combustion air holes. The inner and outer liners (32, 34) each include at least a major air hole (104) having a first hole size, an intermediate air hole (108) having a second hole size, and a minor air hole (106) having a third hole size. The first, second, and third hole sizes are all different from each other.
