Definitions

  • the invention relates to a sailing yacht according to the preamble of claim 1.
  • Sailing yachts in particular high-performance sailing yachts, are designed to be favorable in terms of the use of wind forces, minimization of water resistance and controllability and stabilization. It is desirable that the relevant properties of known sailing yachts are further improved.
  • the object of the invention is to design a generic sailing yacht in such a way that it has significant improvements over previous solutions with regard to the utilization of wind forces, minimization of water resistance and controllability and stabilization.
  • the invention is illustrated with reference to the drawing and explained in more detail in the example description.
  • the figure shows a perspective view of a sailing yacht 1 in the upwind sailing configuration, consisting essentially of a ship's hull 2, a sail 3, which is held by a profile mast 4 in a manner known per se, a canard rudder 8 being arranged below the bow 5 a wing 9 is located at the lower end.
  • the spinnaker usual for sailing in front of the wind and additional special sails for space wind and half wind courses are not shown here.
  • the rear keels 10, 10 ' are pivotably mounted about axes of rotation running approximately parallel to the ship's axis.
  • Each rear keel 10, 10 ' can be pivoted from an approximately vertical to an approximately horizontal position and vice versa.
  • At the lower ends of the bilge keels 10, 10 'a wing 11, 11' is arranged in the manner of an end plate.
  • Each wing consists of a partial wing 14, 14 'arranged on the inside of the bilge keel 10, 10' and a partial wing 13, 13 'arranged on the outside thereof.
  • the inner partial wing 14, 14 ' has an end disk wing 15, 15' at its tip.
  • the wings 11, 11 'together with the wing 9 form a controllable three-point wing system, the wing (9) in particular being used for ramming and longitudinal trim control.
  • the bilge keels 10, 10 ' provide controllable hydrodynamic buoyancy in the case of lateral keel operation. As a result of this wing effect, the friction and wave resistance of the sailing yacht are reduced in a known manner.
  • the windward keel 10 is folded up. In this position, the entire bilge keel 10 is above the water surface, but the long partial wing 14 is partially immersed in the water, so that the end plate 15 now acts as a hydrodynamic support and control element.
  • the end plate wing 15 is operatively connected to a position control, not shown here, of a type known per se, so that heeling control is achieved by means of the controllable end plate wing 15, 15 '. It is particularly advantageous that folding up the bilge keel 10 reduces the hydrodynamic drag of the yacht. Even with the windward keel folded up, the three-point wing system remains, although the surface 11 of the windward keel is replaced by the relevant end disk wing 5.
  • the bilge keels 10, 10 'can have a variable curvature known per se for generating lateral lift.
  • the control of the variable arch elements can be carried out by a control system.
  • ballast containers 17, 17 ' are located at the ends of the bilge keels 10, 10'.
  • These can be a suitable liquid serving as ballast, e.g. Take up mercury, which can be moved by a pump between the two containers 17, 17 '.
  • ballast e.g. Take up mercury
  • an additional displaceable trim ballast in solid or liquid form is used, also coupled with the position control and control system.
  • the profile mast 4 can be pivoted about an approximately vertical axis, which, however, does not coincide with the axis of the mast, but runs steeper than the mast axis. Furthermore, the profile mast 4 is designed according to the invention in such a way that its pointed rear edge has an S-lay from bottom to top in such a way that the profile depth initially increases, then decreases until the S-shape is completed. These measures ensure that the sail 3 twists under the influence of the wind so that it adapts optimally to the wind profile.
  • the front edge of the mast 4 can be designed as a nose flap 18 in a manner known per se to improve the aerodynamic properties of the sail 3. Furthermore, it is conceivable to arrange corresponding slats of known type in the nose area of the mast 4.

Abstract

Un yacht à voile comprend essentiellement une coque et une voile. La voile est retenue sur un mât profilé et la coque comprend un gouvernail et deux quilles de bouchain ayant chacune un ballast et un système de surfaces portantes à trois points qui assure le flottement, la commande et la stabilisation. Selon l'invention, le système de surfaces portantes à trois points comprend un aileron (9) de proue et deux ailerons asymétriques postérieurs (11, 11'), l'aileron (9) formant l'aileron terminal du gouvernail et les ailerons (11, 11') étant agencés de manière similaire aux extrémités des quilles de bouchain (10, 10') et étant pivotables autour d'axes de rotation approximativement parallèles à l'axe du bateau. Le ballast peut être transféré d'un ballast (17, 17') à l'autre. Les axes de rotation des quilles de bouchain (10, 10') sont agencés au-dessus de la ligne de flottaison, de sorte que la quille déployée (10, 10') se situe au-dessus de la ligne de flottaison et seule l'extrémité allongée (14, 14') de l'aileron (11, 11') plonge dans l'eau, l'aileron à ailette terminale (15) agissant comme surface portante.
