Abstract

Le dispositif (10) comporte un arbre (12), un support (14) dudit arbre (12), et au moins une hélice (20) à pales orientables (24). L'hélice (20) comprend un moyeu d'hélice (22) solidaire dudit arbre (12), et des pales (24) chacune orientable autour d'un axe radial (R). Le dispositif (10) comporte un moteur électrique (28), comprenant un boîtier (30) et un stator (42) solidaires dudit support (14), et un rotor (44). Des moyens (61) de liaison cinématique sont agencés entre le rotor (44) et un coulisseau (52) afin de convertir une rotation du rotor (44) en une translation du coulisseau (52) parallèlement à l'arbre (12). Des moyens (62) de liaison du coulisseau (52) avec chaque pale (24) sont propres à convertir une translation du coulisseau (52) parallèlement à l'arbre (12) en une rotation de chaque pale (24) autour de l'axe radial (R) correspondant.

Figure imgaf001
The device (10) comprises a shaft (12), a support (14) of said shaft (12), and at least one propeller (20) with steerable blades (24). The propeller (20) comprises a propeller hub (22) integral with said shaft (12), and blades (24) each orientable about a radial axis (R). The device (10) comprises an electric motor (28), comprising a housing (30) and a stator (42) integral with said support (14), and a rotor (44). Kinematic linkage means (61) are provided between the rotor (44) and a slider (52) to convert a rotation of the rotor (44) into a translation of the slider (52) parallel to the shaft (12). Means (62) connecting the slider (52) with each blade (24) are adapted to convert a translation of the slider (52) parallel to the shaft (12) into a rotation of each blade (24) around the radial axis (R) corresponding.
