Abstract

L'invention concerne un pied de pale d'aérogénérateur formé d'une coquille dont les parois intérieures sont conformées pour y encastrer la pale L'invention est remarquable par le fait que les parois intérieures de la coquille sont recouvertes d'une couche d'un matériau souple. Grâce à l'invention, le frottement, la corrosion et l'abaissement de la limite de fatigue de la pale ne se produisent plus.
