- ガス流ダクト(16、20)と、流れダクト上に位置する燃焼チャンバ(8、28)、および、流れダクト上の、燃焼チャンバの上流側に位置するディフューザ(14、22、23)と、を備え、このディフューザには、エンジンの軸方向に沿うエンジンの角度方向に傾斜が与えられ、こうして、内弧の前を通る流れにおいてガスにある水を凝集させ且つ流れを変化させる湾曲した凹状の内弧が設けられたベーン(15)が備えられ、ベーン(15)は、エンジンの角度方向における配置に従って円に配置され、インジェクタ(9、30)もまた、前記の角度方向における配置に従って配置され、燃焼チャンバが、ベーン(15)の円と同軸の円に配置されたインジェクタ(9、30)を備えている、航空機エンジンであって、ベーン(15)の後縁(34)から来る、前記後縁に対する同じ傾き角度の流れの経路(35)が、ベーン(15)の内弧に対して接線方向であり、ディフューザ(14、22、23)および燃焼チャンバの間を延びる拡散チャンバ(12)内を通った後にインジェクタ(9、30)間を通り、且つ、経路(35)の外側にインジェクタ(9、30)が配置されている方式で、ベーン(15)が、インジェクタ(9、30)に対して角度的に配置された、航空機エンジン。
- 前記経路が、インジェクタ(9、30)間の角度間隔の中間の3分の1の範囲を通ることを特徴とする、請求項1に記載の航空機エンジン。
- 前記経路が、インジェクタ(9、30)間の角度間隔の中間を通ることを特徴とする、請求項2に記載の航空機エンジン。
- ディフューザが、複数の連続する段(22、23)を備え、前記ベーン(15)が流れダクト上の段の1つに属し、この段がもっとも強い変更を流れに適用することを特徴とする、請求項1から3のいずれか一項に記載の航空機エンジン。
- ベーン(15)が、エンジンの角度方向における不規則配置を有し、経路が注入部に繋がる位置にはベーン(15)がないことを特徴とする、請求項1から4のいずれか一項に記載の航空機エンジン。
