Definitions

  • the invention relates to an arrangement for controlling a watercraft using a directional water jet generating device which is pivotally mounted at the stern about a vertical axis from the longitudinal direction of the watercraft.
  • Such an arrangement is e.g. known from DE 32 46 730.
  • a jacketed propeller is connected to the rudder hub of a watercraft, in order to simultaneously deliver control forces via the propeller propulsion and when pivoting the rudder hub.
  • Bow thrusters have the disadvantage that they are too sluggish, ie the switchover time from port to starboard maneuvers is too long until they take effect.
  • the reason for this lies in the steadfastness of the amount of water flowing through and the propeller mass, which must first be reduced to ZERO with their speed potentials and then accelerated again. As a result, rapid and at the same time sensitive maneuvering of the watercraft is made more difficult, if not impossible. If such drives are to be used in connection with sailing boats, further difficulties arise.
  • the device embodied as a water jet drive is mounted so that it can be rotated in and out of an opening of the watercraft by at least ⁇ 180 ° about a vertical axis, and the opening is both in the retracted and is also closed in the extended state of the device by means of closure elements assigned to the device.

  • these shields are in their active position when the drive unit is extended, they prevent the watercraft from sideways dodging or breaking out when the propulsion unit generating the jet jet is turned by ⁇ 180 * from drive ahead to drive back when narrow passages, since after turning the forward drive unit by 90 "the jet is thrust-neutral in the direction of travel and opposite direction by means of the port or starboard sign, which now serve as jet guide surfaces.
  • the second preferred embodiment of the invention according to claim 3 is particularly advantageous for small, medium and large sailing yachts, since the swiveling of the propulsion unit is arranged in the cylindrical casing-shaped housing which is rotatably mounted for the purpose of changing the direction of travel, with the floating unit firmly connected to the propulsion unit. element, the swivel opening in the hull of the watercraft can be closed true to shape and with the same surface, which is particularly space-saving is. Even when the propulsion unit is pivoted out, the bottom flap, which is acted upon by a torsion spring, automatically closes the remaining pivot opening in the fuselage and also stabilizes the propulsion unit in the operative position necessary for the propulsion.

  • the propulsion unit By turning the propulsion unit by ⁇ 180 °, the user of the watercraft has an active rudder that can deliver the full thrust in any direction.
  • the watercraft can be started up with the nozzle extended at a low water speed and a large amount of water and can be moved at an increasing speed by retracting.
  • the associated ring channel is closed successively until only the nozzle itself forms the nozzle jet at high water speed and a small amount of water during the cruise of the watercraft in order to generate the maximum thrust.
  • the pivot axis for the propulsion unit is at the same time a torque-transmitting element for the ring gear provided in the propulsion unit and the rotor connected to it, it is simultaneously used using an appropriate lock against the direction of rotation for pivoting the propulsion unit from the open to the pivoted-in position and vice versa.
  • the universal joint required due to the deformation of the hull of the watercraft and the spline shaft used between the drive motor and the propulsion unit enables the propulsion unit to be arranged eccentrically within the rotatably mounted housing with respect to the direction of travel of the watercraft, so that the interior of the housing is not required is more usable and it is now possible to reduce the swivel angle for swiveling in and out by tilting the drive unit, so that with the most compact design there is still sufficient space for the implementation and the storage of the vertical shaft.
