Abstract

タービン翼（１）を冷却する構造において、高温ガス流路（ＧＰ）に対して凹状に湾曲する第１翼壁（３）と、凸状に湾曲する第２翼壁（５）との間に形成された冷却通路（１７）と、冷却通路に面する両壁面上に設けられた複数のリブを格子状に重ねて構成したラティス構造体（２３）と、隣接するラティス構造体の間に設けられた仕切り体（２７）と、冷却通路内の冷却媒体（ＣＬ）を外部へ排出する冷媒排出口（２５）と、第２翼壁（５）の、冷媒排出口（２５）の外部へ延設された部分である露出壁部（２９）とを備え、仕切り体を介して隣接するラティス構造体（２３）の出口部において、隣接する第１リブ組（３３Ａ）および隣接する第２リブ組（３３Ｂ）が、それぞれ、仕切り体に対して逆向きに傾斜している。
