Abstract
【解決手段】ターボマシン用のブレード形ディスクは円錐状流れ内に延び、かつハンマーヘッド形ファスナによりディスク(12)の周辺溝(7)内に保持されるブレード(1)を含む。ブレードのそれぞれはさらにプラットフォーム(30)を含み、このプラットフォームの半径方向外側面(30a)が気体流の流れの境界面を画定し、また半径方向内側面(30b)が、上流側リブ(32)および下流側リブ(33)を有し、上流側リブ(32)および下流側リブ(33)はディスクの回転軸に垂直な平面内に配置され、かつ上記溝(7)の両側でディスク(12)の周縁部に形成された上流側リング(20)および下流側リング(21)のそれぞれに、これらゾーンの気密性を維持するべく半径方向で近接している。ディスクは、下流側リブ(3)の軸方向の厚みが上流側リング(21)の厚みより厚いことを特徴とする。
