    • An afterburner flameholder for a gas turbine engine having a central diffuser cone, a generally cylindrical outer shell and fuel spray bars between the shell and cone defining an afterburner region is provided, which comprise an annular member with an asymmetric V-shaped cross section. The annular member is adapted to be secured to the engine in the afterburner region with the apex of the V facing upstream in the axial direction toward the fuel spray bars. The annular member has a first and second circular sidewall member each joined at one end forming an apex, the annular member in cross section has unequal length sidewall members. The difference in length between the distal ends of the first and second circular sidewall members is sufficient to cause spanwise vortices shed at the distal ends of the sidewall members to be out of phase when they meet downstream from the flameholder. The different lengths of the distal ends of the sidewall members results in one sidewall member extending further from the apex than the other, situating the distal ends in different planes so that spanwise vortices shed from the asymmetric sidewall members travel different path lengths and are out of phase when they meet downstream.
    • 一种用于燃气涡轮发动机的加力燃烧器火焰发生器,其具有中心扩散器锥体,大致圆柱形外壳和限定加力燃烧器区域的壳体和锥体之间的燃料喷射杆,其包括具有不对称V形横截面的环形构件。 环形构件适于在加力器区域中固定到发动机,其中V形顶点朝向燃料喷杆在轴向方向上游。 环形构件具有第一和第二圆形侧壁构件,每个第一和第二圆形侧壁构件在一端形成顶点,横截面中的环形构件具有不等长的侧壁构件。 第一和第二圆形侧壁构件的远端之间的长度差异足以使侧壁构件的远端处的翼展旋转涡流在与火焰稳定器的下游相遇时脱离相位。 侧壁构件的远端的不同长度导致一个侧壁构件从顶点进一步延伸而不是另一个,将远端位于不同的平面中,使得从不对称侧壁构件脱落的翼展方向涡流行进不同的路径长度,并且离开 它们在下游相遇时。

    • A method for operating a burner including a burner outlet opening with at least two sectors, each sector is assigned at least one fuel nozzle, is provided. The method is characterized in that fuel is supplied separately to the fuel nozzles of different sectors. Also described is a burner which includes at least two sectors wherein each sector is assigned at least one fuel nozzle. The burner includes at least two separate fuel supply lines and a device for adjusting the fuel mass flow which flows through the respective fuel supply line. The fuel supply lines supply fuel to the fuel nozzles of different sectors. Also described is a gas turbine which is fitted with at least one burner.
