  • a steering system have been studied and realized maintaining the rudders retracted on board during the course but capable to be inserted into the water each time when necessary for steering.
  • the immersed rudder was only that one inside the veering.
  • the system was based on the fact that any watercraft having a completely symmetrical keel and with balanced propulsive forces tends to keep a constant direction of the course if no extraneous forces such as wind, wave motion, current etc. intervene to change the direction of navigation.
  • a steering apparatus consisting of a pair of retractable rudders installed abaft the boat outside the transom one on right side and one on left side immersed only when necessary to veering.
  • the equipment object of the invention has the particularity to be used also as stabilisation device in condition of rough sea but also in certain situations as well at high speed when the boat takes a swinging tendency creating serious worries on board.
  • the today's antirolling stabilisation equipments consist generally of a pair of fins similar to rudders outstanding on both sides of the boat under the water level these fins rotating on its axis automatically monoevered from inside board capable to create a couple opposed to that couple created by the rough sea .
  • the system object of the invention is constructively the same in case to be used for steering or for stabilisation of the craft during navigation and it includes in any case at least two units each contained in a watertight housing to be installed one on starboard side and the other on the port side and particularly in case of steering gear the units will be placed with vertical axis abaft the ship while in case of stabilisation gear will be placed near the middle ship prevalently with horizontal axis
  • Each unit contains inside a blade (or a fin) provided with a particular a moving device capable to retract or to project the fin outboard partially or totally when necessary for steering or for stabilising passing trough the bottom of the housing where a suitable slot is provided.
  • Such device consists essentially of a plate 2 joined together with the fin 1 and tilting on a shaft 4 pivoting inside the housing 3 but holding out at least one end 5 passing through a hub 44 provided with a sealing 49 to maintain watertight the housing and at same time to receive the remote control by any kind of electric or hydraulic actuator and at same time to transmit remote information of the fin position.

Abstract

L'invention concerne un système comprenant au moins deux unités dont chacune est contenue dans un logement étanche (3, 33), prévues pour être installées l'une du côté tribord et l'autre du côté bâbord et, en particulier dans le cas d'un appareil à gouverner, les unités seraient placées avec leur axe vertical dans la moitié arrière du navire tandis que, dans le cas d'un appareil de stabilisation, elles seraient placées près du milieu du navire. Chaque unité contient intérieurement une ailette ou une dérive (1) munie d'un dispositif mobile particulier capable de rétracter ou de faire dépasser partiellement ou totalement la dérive hors de la coque lorsque c'est nécessaire pour la direction ou la stabilisation, en passant à travers le fond du logement où une fente appropriée est pratiquée. Dans les deux cas, les ailettes ou les dérives sont normalement maintenues à l'intérieur de leur logement pour réduire la résistance en cours de navigation, tandis qu'elles sont déployées, au choix, du côté droit ou gauche uniquement lorsqu'elles sont activées pour la direction ou la stabilisation, la progressivité de l'action étant obtenue uniquement par le degré d'exposition ou par l'angle d'incidence qui peut varier le long de l'axe de la dérive, et non par rotation de l'axe lui-même comme dans les systèmes connus. Le dispositif de mouvement du système est essentiellement constitué d'une plaque (2) jointe à l'ailette ou à la dérive, basculant sur un arbre (4) pivotant à l'intérieur du logement, mais maintenant au moins une extrémité passant à travers un moyeu muni d'un joint pour maintenir l'étanchéité du logement tout en soutenant un type quelconque d'actionneurs électriques ou hydrauliques fonctionnant dans un lieu étanche et protégé, et capable en même temps de soutenir tous les systèmes de surveillance à distance essentiels pour enregistrer constamment la position exacte de l'ailette et servant à la commande automatique de la route (pilote automatique) ou au système de stabilisation automatique.
