Patent Application - MONOLITHIC COMBUSTOR FOR ATTRITIABLE ENGINE APPLICATIONS > Claims

  • 1. A method, comprising: defining a monolithic apparatus design comprising an outer casing comprising a forward flange, a fuel manifold disposed on the outer casing and defining an annular chamber extending perimetrically around the outer casing, a combustor liner disposed within the outer casing, the combustor liner defining an annular combustion chamber, a first annular plenum disposed between the outer casing and the combustor liner, an inner liner disposed radially from the combustor liner, a first inner flange extending forward from the combustor liner, and a second inner flange extending radially inward from the first inner flange; andmanufacturing a monolithic apparatus based on the monolithic apparatus design using an additive manufacturing process.
    • 2. The method of claim 1, further comprising defining the monolithic apparatus design to further comprise an aft wall of the outer casing at least partially defining a flow path for a flow of air around the combustor liner, wherein the aft wall extends from the inner liner at an angle with respect to a centerline axis of the monolithic apparatus.
      • 3. The method of claim 2, wherein the fuel manifold is disposed radially outward from the first annular plenum.
        • 4. The method of claim 3, further comprising defining the monolithic apparatus design to further comprise a diffuser disposed at an inlet of the first annular plenum and a turbine nozzle disposed at an exit of the annular combustion chamber.
    • 5. The method of claim 1, further comprising defining the monolithic apparatus design to further comprise a gusset extending from a forward edge of the injector port.
    • 6. The method of claim 1, further comprising defining the monolithic apparatus design to further comprise a fuel injector aligned with the injector port and configured to direct a fuel from the fuel manifold to the injector port.
