Abstract
【解決手段】圧力側外壁26と負圧側外壁27とは、前縁28および後縁29に沿って接続し、冷却剤の流れを受け入れるために半径方向に延在するチャンバを形成する。リブ構成は前縁横リブを含むことができる。前縁横リブは、圧力側外壁と負圧側外壁とに接続し、半径方向に延在するチャンバから前縁通路を仕切る。リブ構成はまた第1の中央横リブを含むことができる。第1の中央横リブは、圧力側外壁と負圧側外壁とに接続し、前縁通路の直ぐ後方の半径方向に延在するチャンバから中間通路を仕切る。中間通路は、圧力側外壁と、負圧側外壁と、前縁横リブと、第1の中央横リブとによって画定され、したがって、その外壁間のエーロフォイルにわたる。
【選択図】図4
Description
図5および6は2つの例示的な内部壁構造を示し、これらは、従来の配置を有するロータブレードエーロフォイル25に見られるようなものである。図示のように、エーロフォイル25の外側表面は、比較的薄い圧力側(PS)外壁26と負圧側(SS)外壁27とによって画定することができ、これらは、半径方向に延在して交差する複数のリブ60を介して接続することができる。リブ60は、エーロフォイル25に構造的支持を与えるように構成され、一方では、半径方向に延在して実質的に分離された複数の流路40も画定している。典型的には、リブ60は、エーロフォイル25の半径方向のかなり高さにわたって流路40を仕切るように半径方向に延在するが、流路は、冷却回路を画定するようにエーロフォイルの周囲に沿って接続することができる。すなわち、流路40は、エーロフォイル25の外周側または内周側の縁において流体連通することができ、ならびに、それらの間に位置決めすることがあるいくつかのより小さい交差通路44またはインピンジメント開口(図示せず)を介して流体連通することができる。このようにして、流路40のうちのいくつかは一緒に、曲がりくねった、または蛇行した冷却回路を形成することができる。さらに、フィルム冷却口(図示せず)を設けることができ、冷却剤は、このフィルム冷却口が与える出口を通って流路40からエーロフォイル25の外側表面上に放出される。
