Claims (10)

  1. 燃料ノズル(12)を備え、
    前記燃料ノズル(12)は、
    燃料流れを出力するように構成された燃料噴射器(61、70)と、
    燃料噴射器(61、70)から出力される燃料流れの周囲に配置される予混合器チューブ(52)であって、穿孔部分(74)と非穿孔部分(76)とを備え、非穿孔部分(76)は穿孔部分(74)の下流にある予混合器チューブ(52)と、
    燃料噴射器(61、70)と予混合器チューブ(52)とを取り囲むキャップ(50)と、
    を備え
    キャップ(50)は、燃焼器(16)のケーシング(40)内に配置され、空気を受け取り、空気をキャップ(50)の下流部分(55)に送って燃料噴射器(61、70)の下流部分の冷却を促進し、冷却に使用された空気を予混合器チューブ(52)の上流部分に送るように構成されている、システム(10)。
  2. 穿孔部分(74)の穿孔(58)は、予混合器チューブ(52)に入る空気を旋回させるように構成されている請求項1に記載のシステム(10)。
  3. 旋回の程度は、予混合器チューブ(52)の長さに沿った軸方向位置とともに変化する請求項2に記載のシステム(10)。
  4. 燃料ノズル(12)は複数の燃料噴射器(61、70)と複数の予混合器チューブ(52)とを備える請求項1に記載のシステム(10)。
