Title (EN) REAR SUPPORTING HYDRODYNAMIC ASSEMBLY OF AN OUTBOARD MOTOR FOR A LOWERED MOTOR POSITION
(FR) ENSEMBLE HYDRODYNAMIQUE PORTANT ARRIÈRE DE HORS-BORD POUR POSITION MOTEUR ABAISSÉ
Abstract:
(EN) The invention relates to a rear supporting hydrodynamic assembly of an outboard boat motor on a hull engaging with a set of front foils, the outboard motor being driven by an underwater propeller motor assembly driven by a direct motor shaft actuated by an indirect motor shaft, on a motor propulsion fairing comprising anti-stacking and anti-cavitation plates positioned above the propeller intended for being positioned at the water level, characterised in that the motor fairing is covered by a hydrofoil (10) added at the front onto the direct shaft fairing cone, a deflection crown (80) added above the anti-stacking and anti-cavitation plates and in front of the indirect motor shaft fairing, an added hydrodynamic permeability profile (70) inserted in front of the indirect motor shaft fairing, occupying the space in front of the motor between the top of the anti-stacking and anti-cavitation plates and the bottom of the deflection crown (80), the rear of the hull is provided at the level of the placement of the deflection crown with a deflection plate (90).
(FR) Ensemble hydrodynamique portant arrière de hors-bord naviguant sur une coque coopérant avec un jeu d'ailes avant, le hors-bord est mu par un ensemble moteur à hélice sous l'eau propulsée par un arbre moteur direct actionné par un arbre moteur indirect, sur une carène de propulsion moteur comprenant des plaques anti gerbage et anti cavitation positionnées au- dessus de l'hélice destinées à se positionner au niveau de l'eau caractérisé en ce que la carène moteur est habillé d'une aile portante (10) rapportée à l'avant sur l'ogive de carène d'arbre direct, d'une couronne de déflection (80) rapportée au-dessus des plaques anti gerbage et anti cavitation et à l'avant et de la carène de l'arbre moteur indirect, d'un profil de pénétration (70) hydrodynamique rapporté emboîté à l'avant de la carène de l'arbre moteur indirect, occupant l'espace à l'avant du moteur entre le haut des plaques anti gerbage et anti cavitation et le bas de la couronne de déflection (80), l'arrière de la coque est équipé à hauteur du placement de la couronne de déflection d'une plaque de déflection (90).
