Abstract
【解決手段】冷却空気孔の内部に配置されると共に冷却空気孔5の内壁面から突出して設けられる凸部6を備える。
【選択図】図2
Description
このため、ガスタービンエンジン等が備えるタービン翼には、冷却効率のさらなる向上が求められている。
このように本発明によれば、翼体の外壁面の冷却に寄与する冷却空気を減少させることなく、広い範囲に冷却空気を噴き出すことができ、タービン翼の冷却効率を高めることが可能となる。
図1は、本実施形態のタービン翼1の概略構成を示す斜視図である。本実施形態のタービン翼1は、タービン静翼であり、翼体2と、翼体2を挟み込むバンド部3と、フィルム冷却部4とを備えている。
このような冷却空気孔5は、翼体2の内部空間から供給される冷却空気Yを外壁面2fに向けて案内すると共に、拡径部5bにおいて冷却空気Yを翼体2の高さ方向に分散させて広げてから外壁面2fに沿って噴き出す。
このように本実施形態のタービン翼1によれば、翼体2の外壁面2fの冷却に寄与する冷却空気Yを減少させることなく、広い範囲に冷却空気Yを噴き出すことができ、タービン翼1の冷却効率を高めることが可能となる。
また、図5に示すように、凸部6の下流側には二次渦が形成されていることが分かる。このような二次渦が形成されることによって冷却空気孔5の内部の圧力損失が高まり、冷却空気Yの流速を低下させることができる。この結果、冷却空気Yがより広範囲に広がりやすくなる。
次に、本発明の第2実施形態について説明する。なお、本実施形態の説明において、上記第1実施形態と同様の部分については、その説明を省略あるいは簡略化する。
このように本実施形態のタービン翼においても、翼体2の外壁面2fの冷却に寄与する冷却空気Yを減少させることなく、広い範囲に冷却空気Yを噴き出すことができ、タービン翼の冷却効率を高めることが可能となる。
また、上記実施形態においては、タービン翼が静翼である構成について説明した。しかしながら、本発明はこれに限定されるものではなく、動翼に対してフィルム冷却部を設置する構成を排除するものではない。
また、上記実施形態における凸部6,7の形状は一例であり、例えば、角柱や半円柱形状等の他の形状に変更可能である。
また、上記実施形態における凸部6を直管部5aの内部に設置するようにしても良い。
