Description
それに加えて、既に使用可能状態の動翼の振動数を変更するための方法を国際公開第2003/06260号パンフレットが開示している。この方法によれば振動数を変更するために翼端の領域で翼板に金属被覆が被着され、被覆の厚さは翼後縁で、また翼根部に対して半径方向で、連続的に先細となっている。しかしこれは、こうして動翼の空気力学も変化するという欠点を有する。
その際、翼板中心線に沿って分散配置される複数の穿孔が実施される。翼板中心線は穿孔部を通過して延びている必要はない。穿孔部は翼板中心線の横で翼板中心線に沿って配置しておくこともできる。この配置によって全体としてタービン動翼の一体性と強度が損なわれることはない。所定の質量を翼板の穿孔によって除去しなければならないとき、大きな穿孔深さの穿孔部を僅かな数設けるよりも、むしろ穿孔深さの浅い穿孔部が多数設けられる。
次にタービンのロータに取付けられるとこれらのタービン動翼はタービンロータ用の複数のタービン動翼から成る本発明に基づく翼輪を形成し、この翼輪は高温ガスによって引き起こされる翼板振動励起に対して特別抵抗力がある。その際、翼輪のすべてのタービン動翼が本発明に係る方法で製造されていることが好ましい。
