    摘要: A gas turbine engine has a combustor module including an annular combustor (26) having a liner assembly that defines an annular combustion chamber (30) and includes a circumferential row of a plurality of relatively large combustion dilution air admission holes (116) and a circumferential row of a plurality of smaller quench air admission holes (120) disposed downstream with respect to the flow of combustion gas products. The plurality of quench air admission holes (120) are arranged with respect to the plurality of relatively large dilution air admission holes (116) disposed upstream thereof such that there is associated with each dilution air admission hole (116) a first quench air admission hole (120) and a second quench air admission hole (120), the first quench air admission hole (120) being offset laterally in a first lateral direction and the second quench air admission hole (120) being offset laterally in a second lateral direction opposite to the first direction.

    摘要: A combustor (20) for a gas turbine engine includes a forward bulkhead (22), an inner radial combustor wall (26) and an outer radial combustor wall (28). The forward bulkhead has a plurality of circumferentially disposed injector apertures (34). The inner radial combustor wall is attached to and extends axially out from the forward bulkhead. The outer radial combustor wall is attached to and extends axially out from the forward bulkhead. At least one of the inner radial combustor wall and the outer radial combustor wall includes a plurality of quench aperture sets. Each quench aperture set includes a plurality of quench apertures. Adjacent quench apertures included within each quench aperture set are separated by an intraset distance. Adjacent quench aperture sets are separated by an interset distance. The intraset distance is different than the interset distance. The outer radial combustor wall is disposed radially outside the inner radial combustor wall, thereby defining an annular combustion region therebetween.

    摘要: A gas turbine engine pilot assembly includes a swirler (28) having high and low pressure sides (12, 14). A hood (32) at least partially encloses the swirler (28) on the high pressure side (12). The hood (32) is secured over the swirler (28), in one example. The hood (32) includes an aperture creating a tortuous path from the high pressure side (12) to the low pressure side (14) through the swirler (28). The hood (32) reduces the differential pressure across the swirler (28) by reducing the velocity and pressure of the air before entering the swirler (28). In one example, the hood (32) includes first and second spaced apart walls (38, 40) interconnected by a perimeter wall (36). The walls (38, 40, 36) form a generally annular structure, in one example. At least one of the walls (38, 40, 36) includes an array of apertures (42, 44) communicating with a cavity interiorly arranged within the walls (38, 40, 36) upstream from the swirler (28). Air from the high pressure side (12) flows through the apertures (42, 44) and is slowed before passing through the swirler (28) and into a combustion chamber (20).

    摘要: The present invention relates to a fuel nozzle (10) for use in an engine such as a gas turbine engine. The fuel nozzle (10) includes a fuel injector (14) for injecting fuel into a combustion chamber of the engine and a plurality of rows (16,18) of holes (20) surrounding the fuel injector (14) for eliminating recirculation of hot gas products onto a face of the fuel nozzle. The holes (20) eject air primarily in an axial direction.

    摘要: A combustor for a gas turbine engine includes inner and outer liners 32,34 with a row 112, 114 of dilution air holes penetrating through each liner. The row 114 of holes in the outer liner 34 comprise at least a set of large size, major outer holes 116 and may also include a set of smaller size minor outer holes 118 circumferentially intermediate neighboring pairs of the major outer holes 116. The row 112 of holes in the inner liner include dilution air holes circumferentially offset from the major outer holes 116 and may also include a set of minor holes 122 circumferentially intermediate major inner holes 120 . The major and minor holes admit respective major and minor jets of dilution air into the combustor. The distribution of major and minor holes and the corresponding major and minor dilution air jets helps to minimize NOx emissions and regulates the spatial temperature profile of the exhaust gases discharged from the combustor.
