description PROBLEM TO BE SOLVED: To provide a cooling circuit for cooling a tip area of a multi-wall blade.SOLUTION: A cooling system includes: a forked passage cooling circuit 40, the forked passage cooling circuit including a first leg 42 and a second leg 46; and an air feed cavity 44 for supplying cooling air to the first leg 42 and the second leg 46 of the forked passage cooling circuit 40. The first leg 42 of the forked passage cooling circuit 40 extends radially outward from and at least partially covers at least one central plenum of a multi-wall blade 6. The second leg 46 of the forked passage cooling circuit 40 extends radially outward from and at least partially covers a first set of near wall cooling channels 18 in the multi-wall blade 6.SELECTED DRAWING: Figure 3 【課題】多重壁ブレードの先端領域を冷却するための冷却回路を提供する。【解決手段】冷却システムは、第1の区間42及び第2の区間46を含む分岐通路冷却回路40と、冷却空気を分岐通路冷却回路40の第1の区間42及び第2の区間46に供給するための空気供給キャビティ44とを含み、分岐通路冷却回路40の第1の区間42は、多重壁ブレード6の少なくとも1つの中央プレナムから半径方向外向きに延びてこれらを少なくとも部分的に覆い、分岐通路冷却回路40の第2の区間46は、多重壁ブレード6において壁近傍冷却チャネル18の第1のセットから半径方向外向きに延びてこれらを少なくとも部分的に覆う。【選択図】図3
