Abstract
【解決手段】複数のこのような静翼(30)をタービンに据え付けると、内側及び外側プラットフォーム(52,54)の周方向側縁(56)及び隣接静翼(30)のエーロフォイル(32)の一部によって継ぎ目(78)が形成される。エンジンの作動中、プラットフォーム(52,54)の少なくとも一方に対して高圧冷却材(82)が供給される。冷却材(82)は継ぎ目(78)を通って漏れることが可能である。継ぎ目(78)はエーロフォイル(32)の近傍に位置するから、継ぎ目(78)からの冷却材漏れを活用して、静翼のプラットフォーム(52,54)とエーロフォイル(32)の間の移行領域(86)を冷却することができる。このような冷却効果の恩恵に加えて、本発明はエンジン効率及び部品耐用性をも向上させる。
