Description
(1)翼前縁31におけるチップT1からハブH1にかけての翼角度が、設計点流量における入口流れ角と略同一となるように形成されている。
(2)翼前縁(入口)31から翼後縁(出口)32にかけてのチップT1上の翼角度分布は、スロート部の近傍から上流側において、スロート部の近傍から下流側に比べて翼前縁31に向かって翼角度の減少率が大きく、スロート部の近傍から無次元子午面位置0.9近傍までは、スロート部の近傍から上流側に比べて翼角度の変化率が小さくなっている。ここで、チップT1上の翼角度(チップ翼角度)とは、図3Aのβbtで示される角度を意味する。
(3)翼前縁(入口)31から翼後縁(出口)32にかけてのハブH1上の翼角度分布はスロート部の近傍で変曲点を有し、スロート部より上流側において流れ方向に沿って翼角度の変化率が小さく、スロート部より下流側において翼角度の増加率が大きくなっている。ここで、ハブH1上の翼角度(ハブ翼角度)とは、図3Bのβbhで示される角度を意味する。なお、図3Bにおいては、インデューサの翼部分は点線で示されている。
