  • Slot cooled combustor line
    Patent number: 6675582
    Abstract: A combustor liner for use in a gas turbine engine includes an annular panel section having a cooling nugget formed on one end thereof. An annular cooling lip is formed on the cooling nugget so as to define a cooling slot. The cooling lip includes a hot side, a cold side and a trailing edge surface. The hot side defines a compound taper for minimizing the thickness of the trailing edge surface. In one embodiment, the compound taper includes a first tapered surface disposed on a forward portion of the cooling lip and a second tapered surface disposed on an aft portion of the cooling lip, wherein the second tapered surface has a greater taper than the first tapered surface.
    Type: Grant

  • Low emissions combustor
    Patent number: 6279323
    Abstract: A combustor includes outer and inner liners joined at one end to an annular dome. A swirl cup is mounted to the dome and includes a flare cone extending therethrough. The flare cone has an obtuse flare angle for discharging fuel in a wide spray from an outlet of the cone. A flared beat shield surrounds the cone, and extends in part aft from the cone outlet, and is offset in part forwardly from the cone outlet to define a radially outwardly facing step.

  • Offset dilution combustor liner
    Patent number: 6260359
    Abstract: A combustor liner includes a row of primary dilution holes disposed aft of a forward end thereof, and a row of secondary dilution holes disposed between the primary holes and an aft end of the liner. The secondary holes vary in size circumferentially to a maximum size offset circumferentially from the primary holes.
