Abstract

L'invention se rapporte à un corps en coquille, de construction composite Elle se caractérise en ce que ce corps comporte un bourrelet 13, 14 enrobé dans une matière synthétique armée 18, formant extrémité de raccordement, qui présente une tête arrondie 15 et une queue 16 se rétrécissant de manière continue. Cette construction robuste s'applique notamment à des convertisseurs d'énergie éolienne.The invention relates to a shell body, of composite construction.It is characterized in that this body comprises a bead 13, 14 coated in a reinforced synthetic material 18, forming a connection end, which has a rounded head 15 and a tail. 16 tapering continuously. This robust construction is particularly applicable to wind energy converters.
