Patent Application - SYSTEM FOR AERODYNAMICALLY ENHANCED PREMIXER FOR REDUCED EMISSIONS > Claims

  • 1.-39 (canceled)
  • 40. A system for aerodynamically enhanced Oremixer for reduced emissions, comprising: a premixer being generally cylindrical in form and defined by a relationship in physical space between a first ring, a second ring, and one or more radial vanes, wherein each of the one or more radial vanes is substantially parallel to a centerline of an injector,wherein, the first and second rings include first and second surfaces, respectively, the first and second surfaces facing each other and being generally equidistant, one from the other, at all points thereof and the radial vanes connect the first ring to the second ring and thereby form the premixer, wherein each of the one or more radial vanes has a first end and a second end;wherein the first ring has a first ring outer diameter and a first ring inner diameter as generally measured at a first outer point and a first inner point, respectively,wherein a first inner shoulder is disposed inboard of the radial vanes and a first outer shoulder is disposed outboard of the radial vanes, and wherein the second ring has a second ring outer diameter and a second ring inner diameter as generally measured at a second outer point and a second inner point, respectively,wherein a second inner shoulder is located at a point, viewed in cross section, where the structure of second ring moves through a generally right angle and extends aft of the second ring in a longitudinal direction, thereby forming a chamber inward thereof and being generally cylindrical,wherein, the first and second surfaces contact the first and second ends, respectively, of the one or more radial vanes, and the first and second surfaces are disposed at a non-zero tilt angle relative to a line drawn radially outward from the centerline of the injector, andwherein one or more splitters is provided, disposed generally within the one or more radial vanes.
    • 41. The system of claim 40 further comprising a waveform formed and disposed upon the one or more splitters.
    • 42. The system of claim 40, further comprising the one or more splitters being located axially between the first ring and the second ring, and wherein the splitter defines a forward radial vane disposed between the first ring and the splitter and an aft radial vane disposed between the splitter and the second ring.
      • 43. The system of claim 42, wherein the splitter includes an inner curved portion with a terminal end of the inner curved portion of the splitter being directed aft toward the chamber.
      • 44. The system of claim 42, wherein the aft radial vane has a longer length than the forward radial vane, in an axial direction parallel to the centerline of the fuel injector.
