Definitions

  • the invention relates to a device for compensating for or correcting the heel of a sailing boat with compensation by at least one elongated mobile-type fin member by displacement of the center of gravity, in particular with ballast situated judiciously or by hydrodynamic pressure acting on the active surfaces of this organ in particular the hydrodynamic profile.
  • GB922977 discloses a stabilization system unrelated to the correction of the lodging of a monolithic keel of a sailboat type boat with a displacement on either side.
  • the aim of the invention is to use the sliding displacement to translate on either side of a monolithic keel, the correction element to optimize the hydrodynamic effect of thrust and / or the gravity effect on the attitude. of the boat while controlling the stresses exerted on the correction element in the commanded precision of its displacement in particular by an automatism and its holding in fixed position in particular because of the effect of overhang.
  • the arrangement of the keel with its lateral protuberances advantageously provides a hydro-dynamically neutral position when the correction element is completely inside.
  • the invention described here relates to the direct application on any sailing boat existing or to be built. This application is useful for any unit, whether it is a boat with so-called light, medium or heavy displacements.
  • the invention relates to a structure of a boat keel, in particular a sailboat, which comprises an elongated element for correcting the heel, moving transversely sliding on either side of the plane of symmetry of the monolithic keel located in the direction main boat, with means for translational movement of the elongated member to compensate and / or correct the heel of the boat by gravity and / or hydrodynamic thrust by placing itself in a manner opposite to the heel.
  • the invention relates to a heel control system using a structure of a boat keel with an elongated heel correction element according to the invention which comprises at least one digital computer associated with sensors including d inclination of the boat, speed sensor and / or strain gauge placed in particular on the mast and its guying; said calculator according to programs determined according to characteristics (heel / speed) taking into account the physical parameters present in the environment and the displacement of the boat (FIG. 7) for controlling the driving of said elongate element notably with a servo control loop to correct in real time the list of the boat.
  • the invention described here relates to the direct application on any sailing boat existing or to be built. This application is useful for any unit, whether it is a boat with so-called light, medium or heavy displacements. Reliable mechanical solutions are described below which enable vessels traveling at equal speed to eliminate or reduce the lodging caused by the thrust of the wind on the sail by reciprocity, with equal lodging, there will be increase of the speed.
  • OMCR stabilization mark (2) The movable sliding or rolling member subsequently defined as OMCR stabilization mark (2) is integrated in the keel movably moving transversely.
  • OMCR stabilization mark (2) Apart from the different forms, masses and sections used for the use of the OMCR, several basic ideas are important and can be separated, complementary or inseparable.
  • the upper and lower walls (2a) and (2b) of the movable member are parallel or not to the flow of water; the non-negligible mass moving laterally on starboard or port (right or left) then modify the location of the center of gravity of the hull. It is maneuvered from the control station by manual, electric, automatic or all three.
  • the control means may comprise as mechanical means according to Figure 1, section A: a shaft (5) pinion (6), rack (6a) plus worm gear reducer (not shown); the tightness of the shaft (5) with respect to the aquatic environment is ensured by means of a gland (7) also allowing the assembly to be dismantled.
  • the stuffing box can be placed at a different height depending on whether it is a molded or solid hollow keel from a foundry. The order is made from the cockpit.
  • the control means may comprise as hydraulic means: (2) so-called traction cylinders (not limiting) and references fixed in the keel foot ( Figure 5, for example only). Access for disassembly and internal or external maintenance is done through removable hatches fig.5 mark (1a). It is housed in the thickness of the ballast of the keel (1), the latter being obtained by steelmaking or by composite molding, for example, the monolithic keel as shown in FIG. 5.
  • the ends (2c and 2d, Fig. 1 section A) of the movable member may be flat or shaped according to the parameters notifying a choice.
  • the movable member (fig.1, 2, 3, 4) slides (or rolls) on composite or plastic slides according to the choice of achievements.
  • the movable member (FIG 2) can slide on water film or other in a suitable housing.
  • the simultaneous assistance of a well-known flow pressure group well known in fluid mechanics can be used. (For example, water pump).
  • grooves may be provided in the OMCR (reference (2), fig.1, 2, 3, 4) or in its housing (keel reference (1)). These grooves can be circular, rectilinear or helical or all three.
  • OMCR can be light or heavy, thick or thin. It can also have an active surface as stipulated fig.2 mark (2 s2). It can be of curved shape (fig.4 mark 2), its nonlimiting dimension L (fig.6). Its control is preferably performed by pinion system, rack as defined fig.1.
  • the choice of realization of the OMCR 1,2,3,4 is made according to the parameters defined for the destination of the boat, (for example, cruises boats, races, hirings ....
  • the device fig.5 represents a hydraulic control assembly; only one cylinder is represented; the second is placed on the opposite side.
  • the OMCR is represented in a displaced position on the starboard side. (right side, non-limiting drawing).
