Abstract
L'échasse (6) de cette aube comporte un côté (7) et l'autre (18) pourvu d'une dépression (10). En concentrant cette dépression d'un seul côté, on obtient une échasse (6) plus rigide et résistante à allégement égal, les concentrations de contrainte dépendant de la profondeur de la dépression mais étant absentes du côté (7) plan. Les vibrations et déformations de flexion sont aussi réduites. Application aux aubes de turbomachine, notamment de compresseurs.
