Patent
CA 2373462
The invention relates to a course-stable, fast, seagoing ship comprising a hull that is optimized for a rudder propeller. The inventive ship has a hull designated for accommodating cargo or passengers and has at least one rotatable, preferably electric rudder propeller (POD) (6) which is arranged under the hull of the ship in a gondola-like manner and which comprises at least one motor generator unit for supplying power. Said motor generator unit is arranged in the hull of the ship, whereby the hull of the ship has, at least in part, a bottom (11) which slopes upward approximately to both sides of the hull. The front portion of the hull is designed to stabilize the course and movement of the ship and terminates underwater, in particular, with a relatively narrow bow (2) comprising a bulb (3). In addition, a flow guide body (skeg) (8) which is provided for optimizing the maneuverability characteristics as well as for optimizing the flow against the rudder propeller (6) is arranged in front of each rudder propeller. Said flow guide body has a volume of displacement for the water flowing against the respective rudder propeller.
L'invention concerne un bateau rapide allant en mer, à stabilité de route, dont la coque est déterminée pour recevoir des charges utiles ou des passagers et comprend au moins une hélice de gouvernail (POD) (6) rotative, de préférence électrique, montée en fuseau sous la coque, qui présente au moins une unité moteur-générateur pour assurer l'alimentation en énergie. La coque du bateau présente au moins en partie un fond (11) ascendant quelque peu en direction des deux côtés de la coque. La partie avant de la coque se présente de manière à assurer la stabilité de la course et du mouvement du bateau et se termine sous l'eau, notamment en une étrave relativement effilée avec un bulbe (3) d'étrave. Il est prévu devant chaque hélice de gouvernail un corps de guidage de l'écoulement (crosse) (8), tant pour optimiser les propriétés de route, que pour optimiser l'afflux au niveau de l'hélice du gouvernail, qui présente un volume de déplacement pour l'eau affluant sur chacune des hélices du gouvernail (6).
