Abstract

Propulseur trochoïdal pour application navale Propulseur pour plateforme navale, comprenant : - un carter - un rotor (24) monté rotatif sur le carter autour d’un axe de rotation primaire (X0), et définissant un logement, - un pignon central (30) définissant un axe de pignon central (X1) définissant avec l’axe de rotation primaire un écart (E1), - des pales (32A, 32B, 32C) mobiles en rotation autour d’axes de rotation secondaires (X2A, X2B, X2C), - des pignons secondaires (34A, 34B, 34C) solidaires des pales, et - des systèmes de liaison (36A, 36B, 36C) reliant les pignons au pignon central pour convertir un mouvement de rotation du rotor par rapport au carter dans un sens, en des mouvements de rotation des pales par rapport au rotor en sens inverse, chacune des pales ayant une orientation (D3A, D3B, D3C) fluctuante par rapport au carter autour d’une même direction de cap (D1).
