Definitions

  • the invention is based on adjustable hydrofoils on a watercraft with a shape that repels flotsam, which can be extended or retracted from a defined vehicle speed and retract the aerofoils in the event of a collision with an object from a predetermined impact force, according to the preamble of the first claim.
  • Wings for less friction for higher vehicle speed or lower watercraft consumption have been known since the beginning of the last century and were first commercialized for passenger ships by the Swiss company Supramar AG around 50 years later. Since then, countless developments on motorized ships and boats and sailing vehicles have taken place, such as described e.g. in the US Pat. No. 3,183,871 or US Pat. No. 3,199,484 and US Pat. No. 5,168,824 and regarding wing control, from electro-optical or sonar-based systems to simple and very well-functioning mechanical systems, as described in patent DE 203 10 449 U1 and general trim controls as described in patent US 4,862,820, US
  • the invention is based on the protection of several hydrofoils on a watercraft, which in the event of a collision with flotsam or seabed collapse all of the wings simultaneously and move the watercraft on its usual hull a moment later.
  • the simplest and cheapest solution is a mechanical one Connection of the wing, a folding mechanism to it and that the wing during the folding the previous angle ie Buoyancy remains unchanged.

  • the wings can be mounted on motor and sailing vehicles, four wings, two from two at the rear or three wings two at the rear from one or vice versa, one wing from two at the rear.
  • a total of two effective wings are also possible as continuous U- or V-shaped elements.
  • the wings have a vertical
  • the wings attached to the deflecting arm or acting as part of the deflecting arm can have a T or C or L shape or another hydrodynamic shape and are not the subject of this document, but in particular the wings, which are not attached to two pivot bearings and thus represent a U or V shape , are more sensitive to collision damage, so that in the event of a collision with the outer part of the wing, it turns out from a certain load and creates space for the interference element.
  • the front wing or wings are the most endangered for the watercraft
  • Buoyancy elements While in the event of an impact with an object on the rear hydrofoil, the stern crashes onto the water in the worst case scenario, such a scenario can have a catastrophic effect in the front part, because with the impact of the bow on the water, it can submerge below the water surface and the watercraft - depending on the type and size - overturn, but at least stop extremely quickly, which would not bode well for the passengers on board, as one is not buckled on board and moves freely.
  • the basic version of a mechanical connection of all wings, especially in the version one of two behind, is the easiest and safest.
  • the wings are connected to one another by sensors and monitored so that in the event of an impact, in particular on a front wing, the wing or wings in the rear and the intact front wing immediately retract .
  • a gas detonator such as the one triggered in the automobile for the airbag, the active agent such as a hydraulic cylinder, a gas under pressure can be introduced there, which adjusts the cylinder piston almost suddenly and thus immediately retracts the wing or wings Watercraft do not give the bow a chance to dive into or under the water.
  • the engine speed is reduced via a pre-programmed ramp.
  • the core of the invention is to be able to move such wings faster or more fuel-efficiently by means of extendable hydrofoils, in the event of a collision with a foreign object, the pivot arms of the hydrofoils show a repellent shape in relation to such foreign objects, and in the event of overload, the hydrofoils fold away, with all hydrofoils together mechanically or electronically are connected and act synchronously in the adjustment, the wings remain neutral when adjusting the height, and by detecting the travel distance in front of the wing, a collision with a foreign object is avoided in advance.

  • a watercraft 1 traveling on wing 2 has a large speed advantage due to the lower friction of the missing hull 9 in the water, as well as a significantly lower fuel consumption at medium speed, respectively. lower power consumption when using an electric motor as a drive.
  • Each deflection arm 4 has an angle sensor 7, respectively. in the case of a continuous wing 2 in U or V shape at the rear or at the front, one angle sensor 7 at the rear and one from the front, connected to the controller 12, is sufficient and this is connected to the position sensor 13 and which also acts as an acceleration sensor 13.1.
  • the task of the position sensor 13 is to keep the watercraft 1 stable in the longitudinal direction and in the transverse direction, i.e.
  • the effect is more far-reaching, because the fall from only 0.5 m above the water line WL and at the same time extended deflecting arms 4 does not benefit the passengers on board such a watercraft 1 . Therefore, when registering a fatal collision by means of the position sensor 13 and the angle sensor 7, the rear wings 2 are also retracted, respectively. pivoted up and the wing 2 remains in the horizontal position, so that the watercraft 1 is hardly top-heavy. In the worst case, the optional front wings 14 on the fuselage 9 can prevent the bow from being immersed massively. In this version, the front wing 2 is firmly connected to the deflection arm 4, that is, in one piece and bent accordingly.
  • the deflection arm 4 is attached to a parallelogram 5, an active agent 6 generates a rotary movement on one of the parallelogram arms 5a, so that the parallelogram is moved up or down, according to arrow T.
  • the mechanics attached to it have no hydrodynamic Effects, since the wing 2 is located behind the stage F on the fuselage 9, the stage F allows the water flow to continue flowing and there is no turbulence and the faster the fuselage is moved, the better, since at stage F if necessary, air is also let in laterally and so that the fuselage 9 can be ventilated early and thus the fuselage friction is reduced.
  • the front wing 2 came to be adjusted in the angular position and this is done by means of the trimming mechanism 8, which adjusts the parallelogram 5 on the turntable 16 or one of the means by means of an active agent, not shown here
  • Parallelogram arms 5a or 5b are displaced by an active agent, for example the pivot point from position V to position Z and thus the wing 2 undergoes an angle adjustment, according to arrow Tx and thus the angle of attack and the trim changes
  • the adjustment kinematics on the rear wing 2 is designed more simply here.
  • the wing 2 is connected to the deflection arm 4 via a rotary bearing 17. Details on this are described in FIG. 4.
  • the wing 2 remains at all times in a flat position a with a lift value and in the extended position b of the deflection arm 4, the lift value, depending on the design, can generate a much higher lift value. If the deflection arm 4 is pivoted fully upward, the wing 2 folds up mechanically in a force-controlled manner, described in detail in FIG. 5, so that when the watercraft 1 is moved backwards, the wing 2 is fixed in the port and the water flow is directed downward and the rear is fluidically easier.
  • the drive 10 is independent of the wing 2 and deflection arm 4, but moves vertically similarly or even synchronously, but can trim the thrust without the influence of the wing 2, that is, direct the thrust vector downwards or upwards.

  • the rear kinematics are identical to the front, only the position of the parallelogram 5 is somewhat different depending on the space available and the wing 10 is also attached to the drive 10
  • This is advantageously mounted under the hydrodynamic shape of the wing 2, so that the effect of the wing profile remains optimal Height adjustment T is used to retract and extend the wings 2 and keep them in a constant position, preferably not to cause a negative position when extending and retracting, which can otherwise be fatal, since the watercraft 1 would immediately clap onto the water surface and because of the negative wing position this would pull further down until the watercraft 1 would hardly have propulsion anymore, but the cockpit could already be filled with water and could remain just below the waterline WL1.
  • the height adjustment T also serves to use it as a trim in the extended state in order to optimally adjust the longitudinal position of the watercraft 1.
  • the active agent 6, which is, for example, a hydraulic cylinder, has a fluid collecting container 20 and a gas cartridge 21 with a trigger 22. If the impact of the collision object 3 with the front wing 2 or. Deflection arm 4 is so large that it is withdrawn for safety reasons, it must be done at lightning speed and thus a hydraulic pump cannot allow the fluid to flow out of the cylinder space sufficiently quickly, so that a pressure relief valve 20a on the fluid collecting container 20 diverts the fluid there.

  • the engine speed is reduced via a ramp, so that the damage can possibly be detected before accelerating again and, by means of the speed detection, the controller 12 automatically extends the wings 2 again
  • At least one distance detection sensor 18 is located on the front wing 2, which detects such undesired objects in a specific measuring cone region. This sensor not only detects the distance, but also analyzes the size and shape of the object.
  • the controller 12 can automatically convert such values output by the distance and object detection sensor 18 into a speed-reducing mode and the wing 2 retracting mode without the skipper having to constantly look at the image device.
