Abstract

L'invention concerne un propulseur de type creux destiné à un véhicule de déplacement à la surface d'eau. Le propulseur de type creux comprend un ensemble de propulseur - tube creux et un propulseur formé sur la surface périphérique interne du tube creux. Pendant la rotation, le propulseur est capable d'éjecter de l'air ou de l'eau à une vitesse élevée. Une roue dentée transfère une puissance d'entraînement à un moteur du véhicule de déplacement à la surface d'eau au moyen d'un arbre de transmission de puissance à l'ensemble tube - propulseur. Une couronne est formée intégrale avec la surface de périphérie interne du tube creux et mise en prise par la roue dentée. Un boîtier de propulseur du type à tube creux est formé à l'extérieur de l'ensemble de tube à propulseur. Le propulseur peut assurer l'aspiration et la propulsion d'eau ou d'air lors de sa rotation à haute vitesse, grâce à la puissance de transmission transférée par la route dentée, de manière à ce que la force générée suffise pour déplacer le véhicule de déplacement à la surface d'eau.
