Definitions

  • the invention relates to a water jet drive for watercraft.
  • an impeller In conventional water jet drives, an impeller is mostly over a horizontal one Drive shafts, but also driven by vertical drive shafts. The impeller accelerates the water and applies swirl and pressure energy to it. integrated Stator blades set the swirl energy and nozzle-shaped outlets set the pressure energy in flow energy, i.e. in thrust to.
  • Water jet drives with a vertical drive shaft have the advantage that they have the Thrust via outlet nozzles arranged in the housing base or via deflection fins in full control with 360 °.
  • a disadvantage of these drives however, that the flow is several times strong up to the sloping outlet under the floor redirect. As the journey increases, the one to be redirected upwards in the intake area begins To cut off the flow, which results in a thrust drop and the efficiency further diminishes.
  • Water jet drives with a vertical drive shaft are mainly used in displacement ships as maneuvering and auxiliary systems in the bow, but also as main drives in the stern shallow ships with special maneuvering properties.
  • Water jet drives with a predominantly horizontal drive shaft have that Advantage that the water flow for thrust generation has to be deflected far less than for drives with a vertical drive shaft.
  • the power transmission takes place direct path (i.e. without angular gear) and the sense of control remains when reversing receive.
  • These drives are mainly used as main drives to control and lighter faster gliding boats, but also used in special fast ships. In displacement vehicles they are rather rare to find.
  • Variants i.e. drives with two impellers
  • the usual steering devices of water jet drives with predominantly horizontal ones The drive shaft has a swivel nozzle for control in advance and for reverse thrust Deflection elbows, deflection flaps and / or bottom deflection blades.
  • the steering angle is usually limited to ⁇ 30 - 35 ° to port and starboard.
  • This Thrust reversers usually generate when maneuvering (e.g. turning over the Port or starboard side) in addition to the transversal thrust component inevitably one more or less disruptive backward thrust component, which means more precise control difficult.
  • the transverse thrust sufficiently generated for gliding vehicles is for displacement vehicles with a naturally higher demand rather scarce and for agile maneuvering insufficient.
  • the exit jet can usually Take up air when reversing is transported forward and then the development of the reverse thrust more or less impaired.
  • the invention has for its object an inboard water jet propulsion to be specified with a predominantly horizontal drive shaft, that for different aft vessels can be modified with different inflow conditions, the components remain unaffected for drive and control. From water intake to An optimal thrust with at least two propulsion variants should be generated be efficient in at least all with a tail unit that can be integrated into the housing 4 main directions: forward, back and in both transverse directions (to port and Starboard) is deflectable and the - mainly displacement vehicles - the watercraft gives optimal driving and maneuvering properties and their shallow water suitability guaranteed.
  • the invention is essentially based on the idea of the functional parts of the water jet drive to be arranged in a container-like housing so that the water jet drive in a simple way in a prepared opening in the hull of a watercraft is insertable.
  • the housing is on the front with a water inlet Flow channel connected, which also receives the drive shaft.
  • a tubular section (propulsion housing) is provided, which to the flow channel via an opening in the front transverse wall of the housing connects and at least one of a drive motor via a horizontal drive shaft rotatable impeller, at least one rectifier, and a nozzle outlet includes, so that when the water jet drive is used as intended Impeller water supplied through the flow channel, this accelerates and then with is expelled at high speed through the nozzle outlet.
  • the water jet drive further comprises at least one downstream of the nozzle outlet Guide device partially arranged in the container-like housing with at least two side rudder flaps that move from a rest position to a side at the same time Control position are pivotable, and a deflection flap pivotable into the water jet.
  • the deflection flap and the two rudder flaps form the base plate the container-like housing and an upper cover plate arranged in the housing and a sealing plate arranged vertically in the area of the nozzle outlet, a chamber, such that the water jet emerging from the nozzle outlet when the deflection flap is closed and rudder flaps in their rest positions essentially only by a floor deflection grid provided in the base plate can be deflected forward.
  • the Deflection flap has lateral guide fins which are designed such that with the deflection flap closed and the rudder flaps pivoted out of their rest position a transverse opening between the fin and the corresponding rudder flap contour through which the water jet emerges controllably from the chamber in the transverse direction, the contour of the side surfaces of the container-like housing in this area is chosen that the water jet is not hindered.
  • the invention can be used for various types of watercraft in glider or Displacement type are used, e.g. for dinghies, pleasure boats, landing craft, Company vehicles, passenger ships, ferries, work ships, cargo ships, vehicles with special requirements for holding positions, e.g. Diving support ships.
  • the flow channel is designed such that that the water can be fed horizontally from the front.
  • Known water jet drives however, absorb the water from below through a bottom opening.
  • shallow water i.e. with a keel clearance below 20 cm
  • these are known Drives suffer additional losses because of the tough boundary layers on the outer skin and reason obstruct the water flow to the impeller.
  • the impeller's suction effect is reduced thrust while increasing ship resistance.
  • the disadvantages of conventional floor inlets with inflow from below are due to unfavorable deflections and channel friction on the suction side of the impeller and the dreaded vacuum cleaner effect that is feared in shallow water use.
  • the rear bearing of the drive shaft can be sealed in a stern tube (with Bearings) or without, i.e. wet running (in a water-lubricated plain bearing). Then either the stern tube in front of the impeller is in a support star in the inlet channel to be arranged, the webs of which are shaped in such a way that the water is as possible to the impeller is supplied swirl-free, or in the case of a wet shaft, this is in the center of the Guide vanes arranged behind the impeller, the swirl energy in flow energy implement, stored.
  • the propulsion housing has in the area of the impeller has a circular cross-section and one in the area of the outlet nozzle essentially square cross-section, with the inner contours between the two Form cross-sectional fins guide surfaces that are coiled so that the water exits the nozzle leaves with reduced swirl.
  • This configuration is supplementary or alternative can be realized as fixed guide vanes behind the impeller.
  • control flap of the guide device that is pivoted to the side to be controlled, each has a larger angle than the adjacent control flap. This ensures that a predominantly cross-directional Thrust to port or starboard is generated.
