Abstract

Selon l'invention, un entraînement pour un navire marin peut comprendre une hélice entièrement immergée avec un arbre d'entraînement fixe configurant l'hélice dans un mode de traction, l'hélice tirant l'eau vers l'arrière par rapport à une proue du navire marin lors du déplacement dans une direction vers l'avant. L'hélice est montée de préférence dans une plage de 10 % à 60 % d'une longueur du navire marin vers la proue à partir d'un tableau et fonctionne sans cavitation.
