Based on the law of dynamic water-separation, in this invention, a new type of
front-mounted booster water-separation propeller has been designed to raise a
vessel's speed by reducing resistance from water and increasing the advance
force. It's composed of two parts, of which the external includes an influent
tube (1), a left thin, flat gushing gutter (2), a right thin, flat gushing
gutter (3), and screwed connections (6), of which interior includes a booster
(4) and its axle (5). Both parts can be changed independently.
L'invention concerne, sur la base de la loi de la séparation dynamique de l'eau, un nouveau type d'hélice de séparation d'eau à renfort, à montage avant, mis au point pour augmenter la vitesse de rotation d'une cuve, par réduction de la résistance côté eau et par augmentation de la force d'avancement. Ladite hélice comprend deux parties. La partie extérieure comporte un tube affluent(1), un trop-plein de débordement (2) plat et mince, gauche, et un trop-plein de débordement (2) plat et mince, droit, ainsi que des raccordements vissés (6). La partie intérieure comprend un élément de renfort (4) et son axe (5). Les deux parties peuvent être remplacées indépendamment l'une de l'autre.
