Abstract

Un propulseur ondulatoire utilisant l'énergie du tangage d'un bateau (1) comprend des pales (2?I, 2II, 2III¿) sous-marines reliées entre elles, les unes après les autres, par des tiges flexibles (5?I, 5II, 5III, 5IV¿). Une pale (2I) est reliée au bateau par des tiges flexibles (4I, 4II) et une pale (2III) est aussi reliée par des tiges flexibles (6I, 6II) à un plateau plongeur (3) hydrodynamique. Chaque ferrure de fixation des extrémités de tiges flexibles (4?I, 4II, 5I, 5II, 5III, 5IV, 6I, 6II¿) aux tiges (2?I, 2II, 2III¿) est réalisée sous forme de broche (9) engagée dans une rainure (8) de manière à pouvoir tourner autour de l'axe, qui est parallèle ou convergent par rapport à la portée de la pale (2?I, 2II, 2III¿). L'utilisation du propulseur ondulatoire garantit, sur différents bateaux, une adaptation automatique de l'angle d'attaque de chaque pale au changement de vitesse du bateau (1).
