Abstract
(EN)
The invention relates to a nautical propulsion device having improved economy and improved control of the masses of water used. Said device consists of a "supporting base" (B) (handle or bar), which extends a "blade" portion also known as a "dynamic fuselage" or "reactor" (A) consisting of a single "wall" (1) or "wall structure" completed by at least one "opening or channeling furrow" (2); the "blade" of same being used at 90°, as opposed to a conventional oar, resulting specifically in the water surging thereupon being constrained so as to process the flows thereof propulsively; the "wall" portion is defined along a mean center line of symmetry (C) which formally qualifies same as the principle of a sufficiently tapered "leading edge" or "section" (3) for accurate control and steering. The device according to the invention is intended specifically for propelling water craft.

L'invention décrit un dispositif de propulsion nautique d'une meilleure économie et d'un meilleur contrôle des masses d'eau utilisées. Il se compose d'une "base de maintien" (B) ( manche ou barre ) que prolonge une partie "pelle" dite "fuselage dynamique" ou "réacteur" (A) formée d'une unique "paroi" (1) ou "structure formant paroi" complétée par au moins une "ouverture ou sillon canalisant" (2); sa "pelle" étant à utiliser à 90° différemment qu'une rame classique en amenant spécifiquement à contraindre l'eau s'y engouffrant pour en traiter les flux de façon propulsive; la partie "paroi" est déterminée selon un plan médian moyen de symétrie (C) qui en qualifie formellement le principe d'un "bord d'attaque" suffisamment effilé ou "tranche" de contrôle et de direction précis (3). Le dispositif selon l'invention est particulièrement destiné à la propulsion des embarcations.
