Claims (5)
- 翼形部支持体(12)とこの翼形部支持体(12)を取り囲む外被(14)を備え、この外被(14)が、翼形部支持体(12)と外被(14)との間に冷却材で貫流される中間室(18)を形成するために、複数のスペーサ素子(16)により翼形部支持体(12)に間隔を隔てて結合されているタービン翼(10)であって、
外被(14)が薄肉に形成され、翼形部支持体(12)に複数のスペーサ素子(16)により点状に結合され、それらのスペーサ素子(16)が平面的に分布して配置され、前記スペーサ素子がそれぞれ、翼形部支持体(12)と外被(14)にろう付けによって結合される球形ろう材(16)の形態に形成されており、前記球形ろう材(16)が部分的にしか溶融されないことを特徴とするタービン翼。 - 前記スペーサ素子(16)の平面的分布が一様に行われていることを特徴とする請求項1に記載のタービン翼。
- 中間室(18)が隙間状に形成され、その横断面が翼前縁から翼後縁にわたり同じ隙間寸法を有していることを特徴とする請求項1又は2に記載のタービン翼。
- タービン翼(10)が翼脚を有し、この翼脚が、中間室(18)が翼脚から始まって冷却材で貫流されるように形成されていることを特徴とする請求項1ないし3のいずれか1つに記載のタービン翼。
- 翼形部支持体(12)とこの翼形部支持体(12)を取り囲む外被(14)を有し、この外被(14)が翼形部支持体(12)に間隔を隔てて結合され、その外被(14)を翼形部支持体(12)に間隔を隔てて結合するために、外被(14)が翼形部支持体(12)の複数の箇所で翼形部支持体(12)にろう付けされているタービン翼(10)の製造方法であって、
外被(14)が翼形部支持体(12)に複数のスペーサ素子(16)により点状に結合され、それらのスペーサ素子(16)が平面的に分布して配置されており、前記複数のスペーサ素子(16)が、翼形部支持体(12)の外被(14)との結合時に部分的にしか溶融されない球形ろう材(16)を含んでいることを特徴とするタービン翼の製造方法。
