Definitions

  • the invention relates to a keel device for sailing ships, in particular for single hull sailing yachts, with the characteristics of the introductory Part of claim 1.
  • Such a keel is known from GB 2 232 126 A.
  • keel in sailing ships, especially in single hull sailing yachts, on the one hand, consists of enlarging of the lateral plan the shear force necessary for sailing in the water generate to create a reaction to wind shear force on the sail.
  • keels on sailing ships serve to absorb ballast, to increase the stability of the ship, because the attacking in the sail Wind momentum creates a moment that the sailing ship after Lee is cringing. This moment must be countered by a corresponding counter moment of the ballast emigrating to windward are partially counteracted.
  • the focus of the propulsion also works in the sail in the lee, the main focus of propulsion resistance total wetted area of the underwater ship including the Kiels is in the windward.
  • the distance between the resulting propulsive force in the sail and resulting resistance in the water creates a moment that makes the ship greedy.
  • the rudder blade is at an angle to the direction of travel and generated an additional flow resistance.
  • the deepest hydrodynamically are in the longitudinal direction of the ship short keels, i.e. keels with a large extension and ideal profile cross sections. In addition to lower ones because they are lower lying Ballast and thus less wet area with the same hydrostatic These keels exhibit stability even the slightest "induced Resistance "as the largest share of resistance the well-known keel shapes. This resistance will by pressure equalization around the lower keel edge of the pressurized Leeward side of the keel to the windward side of the Kiels caused because of an extremely unfavorable flow vortex arises. There is a reduction in the induced resistance only by partially preventing the flow around the bottom edge of the keel possible with wings. However, these increase the wetted area and thus the frictional resistance of the underwater ship.
  • the invention has for its object a sailing ship with a keel, especially a sailing yacht, so that the keel without adverse influence on the sailing properties, rather these beneficial support, adapted to the respective operating conditions can be, with course changes especially when turning or neck up a quick change of wing keel and ballast keel the new course should be possible.
  • this task is performed on a sailing ship with the Features of claim 1 achieved.
  • the ballast keel can for it to be pivoted towards windward, creating the righting moment is increased.
  • severe heeling e.g. in the event of a gust of wind the keel ballast swiveled towards windward under certain circumstances out of the water, which on the one hand eliminates its buoyancy and thus the uprightness Moment of the ballast keel is further increased, on the other hand the falls wetted area of the keel ballast away, causing its friction in the There is no water.
  • Both keels not only the ballast keel, but also the wing keel, can, e.g. for cruising yachts, equipped with ballast be so that they face each other at the same swivel angle Balance the sides or with very sporty yachts much higher ballast keel moment in relation to the wing keel moment be carried out at the same swivel angle.
  • the sailing yacht in the harbor is only vertical when the ballast keel is pivoted less far than the wing keel.
  • ballast keel For larger sailing yachts or if higher course stability is desired is also a keel device with two wing keels and one in particular, ballast keel arranged between them possible.
  • ballast keel arranged between them possible.
  • Another way of rapid equalization of the moment of both keels when turning consists in that the potential energy of the more swung out and therefore Ballast keel located higher by pressure diversion into the lower lying keel lowers the first and lifts the second until a Torque compensation is reached.
  • the swung-up keel parts e.g. by means of rope slings, in their position are held so that the swivel drive for the keel parts is relieved.
  • Fig. 11 shows an embodiment for the Keel drive of a keel device with three keels

  • Fig. 2 shows the yacht with swung out on opposite sides Keels 1 and 2.
  • Fig. 3 shows the yacht offended, the wing keel 1 vertical is set in order to achieve the largest possible lateral plan.
  • the Ballast keel 2 is pivoted upwards on the windward side so that Ballast body is above the water level in order to be as large as possible to generate the righting moment.
  • Fig. 4 shows a yacht in side view with a wing keel 1 and a ballast keel 2.

  • An overflow valve 14 ' allows quick opening of the keel 1 by opening and / or 2 when changing course to the other bow. Equivalent is achieved by pressure equalization between the loaded cylinders Keels 1 and 2 by opening the connecting line 29a and 29b reached. This is where the torque is balanced and thus the vertical position the yacht also takes place when keels 1 and 2 are still do not stand vertically. There is also an energy potential here consist.
  • a rechargeable hydraulic accumulator 13 has the advantage that it can be charged unloading can be done slowly, i.e. with low power consumption but can be done quickly with high power output.
  • There a Hydraulic accumulator 13 loses pressure when dispensing volume, to Swiveling up a keel part just towards the end of the possible Swivel angle the highest pressure is needed is the division of the hydraulic accumulator in several pressure levels is an advantage. In This case could also be strong with the potential energy swung out keel, i.e. loaded with the highest pressure level Keel, when returning this keel a lower pressure level of the multi-unit hydraulic accumulator charged without external energy supply become.
