Abstract

L'invention divulgue un dispositif de propulsion de bateau, comprenant un propulseur à hélice qui utilise une chape de propulseur équipée d'ailettes, le dispositif de propulsion de bateau présentant une meilleure maniabilité et un poids moindre qu'un dispositif de propulsion de bateau qui utilise une chape de propulseur pourvue d'ailettes présentant une forme de la technique antérieure. L'invention divulgue également un bateau équipé du dispositif de propulsion de bateau. La forme de la moitié arrière des ailettes (6) est conçue de telle sorte que, avec le diamètre (Dcf) de l'extrémité avant d'une chape de propulseur (5) qui est défini comme diamètre de référence (Ds), la forme est contenue à l'intérieur d'un cône tronqué qui est formé entre les bases de celles-ci qui forment un cercle (C3) qui est centré sur le centre de rotation du propulseur et qui présente un diamètre (D3) qui est défini à la position centrale (Xm) entre l'extrémité avant (6f) et l'extrémité arrière (6a) du pied de chaque ailette (6) et qui est égal à 2,0 fois le diamètre de référence (Ds), et un cercle (C4) qui est centré sur le centre de rotation du propulseur et qui présente un diamètre (D4) qui est défini à la position arrière extrême (Xe) de l'ailette (6) et qui est égal à 1,5 fois le diamètre de référence (Ds).
