Abstract

L'invention concerne des générateurs d'éolienne et des procédés de fixation de différents types de pale sur le moyeu d'un générateur d'éolienne. Comme ces différents types n'ont normalement pas de moyens de fixation de conception identique sur le moyen, il est impossible de relier ces types différents à un moyeu donné. Les procédés reposent sur l'utilisation d'adaptateurs de moyeu qui assurent la liaison avec différents types de pale. Un adaptateur de moyeu comprend au moins trois moyens de fixation de conception différente de sorte qu'au moins deux pales différentes puissent se rattacher à un moyen ou que l'adaptateur soit compatible avec au moins deux types de moyeu, chacun étant configuré avec différents moyens de fixation.
