Abstract
La bride (11) d'une plate-forme (10) de pied d'aube est séparée d'un bord adjacent (31) de la pale (4) par une gorge (18), qui évite une transmission directe des efforts produits par la fixation par boulonnage de la bride (11) de la plate-forme à la partie voisine de la pale 54) et réduit les concentrations de contrainte.
