Turbofan augmentor flameholder

Claim 1

In a turbofan engine having a casing enveloping a compressor, combustor, turbine and augmentor in axial flow relationship, the improvement therein being in the form of a flameholder located in said augmentor of said turbofan engine downstream of said turbine, said flameholder comprising a hollow ring-like structure of annular configuration concentric with the centerline of said turbine, said ring-like structure being open in the direction of said turbine forming a pilot section, a first group of radially disposed hollow gutters extending from said ring-like structure in a direction toward the centerline of said turbine, a second grip of radially disposed hollow gutters extending from said ring-like structure in a direction away from the centerline of said turbine toward said casing of said turbofan engine, an aperture located in said ring-like structure aligned with each of said gutters interconnecting said pilot section with said gutters, said second group of gutters having a vee-shaped angular configurated portion in a direction toward said turbine, said angular configurated portion gradually increasing in angle size along said gutter in the radial direction as a function of its distance from said ring-like structure whereby hot gases produced by said turbine flow to said pilot section and out said radially extending gutters.
