Definitions

  • the present invention relates to wave generating systems.
  • the invention particularly relates to wave generating systems that facilitate modulation of a wake generated by the system.
  • a wave generating system comprising:
  • the wake modulator comprises contours of a floor of the wave pool and wherein the travel path of the hull is non-parallel with the contours.

  • the travel paths of the hulls may be substantially identical, and the hulls disposed at a distance from one another such that wakes generated by a prior hull are superimposed by wakes of a following hull.
  • the travel paths of the hull and the other hull may alternatively be towards one another such that the wake and the other wake intersect to form a bulge that advanced laterally across the wave pool.
  • the travel paths of the hull and the other hull may alternatively be in the same direction on opposing sides of the wave pool such that the wake and the other wake intersect to form a concave wave front disposed between the travel paths.
  • the wake modulator comprises a submerged foil adapted to travel along a travel path parallel to the travel path of the hull and at a predetermined distance preceding the wake generated by the hull such that the foil forms a trough that modulates the wake.
  • the wake modulator comprises a submerged reef adapted to travel along a travel path parallel to the travel path of the hull and at a predetermined distance behind the hull such that the wake generated by the hull travel over the reef as the reef advances, thereby causing the wake to break over the reef.
  • the submerged reef may comprise an adjustable panel that can be adjusted relative to the wake of the hull.

  • the present invention relates to recreational wave pools.
  • the purpose of this invention is to change wave shape to suit various aspects of surfing performance.
  • the present invention provides for at least one of the following:
  • FIG. 1 depicts a system 100 in which a hull 105 moving along a travel path 110 proximate the edge of a pool 115 , in a direction that is parallel to the contours 120 of the pool floor, such that the resulting wake 125 advances at a constant angle, depicted here as 45 degrees to the contours 120 , upon which the wake is designed to break.
  • FIG. 2 depicts a similar system 200 having the same elements as FIG. 1 , except that the travel path 210 of the hull 205 is now five degrees off parallel to the contours 220 of the pool floor, resulting in a five degree reduction in the angle of its wake 225 , which now advances at an angle of 40 degrees, instead of 45 degrees, as depicted in FIG. 1 .
  • the angle of the travel path 210 of the hull 205 may advantageously be modified to modulate the angle of the wake 225 relative to the contours 220 of the pool floor.
  • FIG. 3 depicts an alternative system 300 having the same elements as FIG. 2 , except that the hull 305 now follows a meandering path 310 , resulting in the angle of its wake 325 changing in response to the various directions followed by the hull 305 .
  • the meandering path 310 increases wave power by compressing the wave front each time it turns toward the side that releases the wake 325 .
  • a vertical panel 430 is suspended longitudinally from one side of the hull 405 , to prevent a wake 425 ′ from forming on that side of the hull 405 , when its path takes it away from the pool wall 415 , which would otherwise prevent the desired wake 425 from forming.
  • FIG. 4 depicts the undesirable occurrence of the wake 425 ′ bouncing off the wall 415 of the pool.
  • FIG. 5 depicts the hull 405 with a vertical panel 430 suspended from one side and extending beyond the stern of the vessel.
  • the hull 605 is supported by a carriage 635 , which allows it to pivot on the horizontal plane, so it can be aligned with the direction of its movement through the water along the travel path 610 .
  • FIG. 6 depicts the relationship between the alignment of the hull 605 , the travel path 610 it follows and the carriage 635 supporting it.
  • the systems of FIGS. 2-6 may further provide for altering the depth of the hull while it is being driven along the travel path such that the magnitude of its wake increases or decreases accordingly.
  • the systems may provide for alteration of the width of the hull while it is being driven along the travel path such that the magnitude of its wake increases or decreases accordingly.
  • the systems may provide for increasing or decreasing the speed of the hull, such that the magnitude of its wake increases or decreases accordingly.
  • a plurality of hulls may also be driven along the travel path on side of a channel, with successive hulls moving at different speeds, such that their wakes vary in size and speed.
  • a plurality of hulls is driven in close succession along the side of a channel, such that key differences in their size, draft and trim angle result in variously angled wakes, which subsequently intersect to produce favourable effects on the resulting wave.
  • FIG. 7 depicts two hulls 705 , which are traveling along the same path, but are producing differently angled wakes 725 , which subsequently intersect as they enter shallow water.
  • the plurality of hulls 805 , 805 ′ are advantageously driven along the wall of a pool 815 with the hulls 805 , 805 ′ spaced precisely one wavelength apart, such that the second wake 825 ′ from the preceding hull 805 merges with the first wake 825 ′′ of the following hull 805 ′.
  • FIG. 8 depicts a single hull 805 producing a train of two wakes 825 and 825 ′.
  • FIG. 9 depicts two hulls 805 , 805 ′ advancing along the same path, with each hull 805 , 805 ′ producing a train of two wakes, such that the first wake 825 ′′ of the trailing hull 805 ′ becomes aligned with the second wake 825 ′ of the preceding hull 805 .
  • the wave size relative to energy input may be increased, while simultaneously maximising their rate of production, since the wave length of the preceding hull's wake determines how close the next hull can trail, without its wake unduly distorting the preceding hull's wake.
  • the speed of the hulls may be controlled by a programmable logic computer, such that the distance between successive wave generating bodies maintains the correlation with wave length, as the resulting waves build in size and their wave lengths increase.
  • two hulls 1005 , 1005 ′ are driven toward each other, along one side 1015 of a channel, such that their wakes 1025 , 1025 ′ intersect to form a bulge 1040 , which advances laterally across the pool, directly toward the shallows, where it forms into a peak, as it breaks.
  • two hulls 1205 , 1205 ′ are driven along opposing sides 1215 , 1215 ′ of a channel, in the same direction, such that their wakes 1225 , 1225 ′ intersect in the middle of the channel, where they converge to form a concave wave 1240 front that advances along the centre line of the channel for as long as said wakes 1225 , 1225 ′ continue to intersect.
  • a submerged foil 1350 is driven along a horizontal path 1355 , in front of a wake 1325 such that its effect upon the surface contours of the water converge with the wake 1325 .
  • the method of propulsion could be self-contained, as with a submarine, or via a track fixed to the pool floor.
  • FIG. 14 depicts a cross-section A-B of the submerged foil 1350 , followed by a trough 1360 , which affects the wake 1325 , by increasing the depth of its trough 1365 and the height of its crest 1370 .
  • a hull 1505 produces a wake 1525 , which forms into a breaking wave 1525 ′ as it crosses over a reef 1550 driven along a parallel path 1575 .
  • the wake 1525 intersects the path 1575 of a reef 1550 , for example moving along a track, maintaining its position below the advancing wake 1525 .
  • FIG. 16 depicts the cross-section A-B, identified in FIG. 15 , showing the reef 1550 , causing the wake 1525 to break in a manner determined by the shape and proximity of the reef 1550 .
  • a hull produces a wake, which forms into a breaking wave as it crosses over a reef in the form of a submerged panel, which is driven along a path that is parallel to the path followed by said hull.
  • FIG. 17 depicts this arrangement, viewed from above, in which a hull 1705 produces a wake 1725 that intersects the path of a submerged panel 1750 , which maintains its position below the advancing wake 1725 , by moving along rails 1780 fixed to the pool floor.
  • the position of the submerged panel 1750 is flat with respect to its direction of movement. In cross-section, the submerged panel 1750 is curved, with its convex surface facing upward.
  • FIG. 18 depicts the cross-section A-B, identified in FIG. 17 , showing the submerged panel 150 , causing the wave to break 1725 ′ in a manner determined by the shape and proximity of the panel 1750 .
  • FIGS. 19 and 20 depict the same cross-section, now showing how the submerged panel 1750 can be repositioned at different depths and different angles, to change the shape of the wave 1725 ′ breaking above it.
  • FIG. 18 depicts the cross-section A-B, identified in FIG. 17 , showing the submerged panel 150 , causing the wave to break 1725 ′ in a manner determined by the shape and proximity of the panel 1750 .
  • FIGS. 19 and 20 depict the same cross-section, now showing how the submerged panel 1750 can be repositioned at different depths and different angles, to change the shape of the wave 1725 ′ breaking above it.
  • FIG. 18 depicts the cross-section A-B, identified in FIG. 17 , showing the submerged panel 150 , causing the wave to break 1725
  • FIG. 20 depicts the submerged panel 1750 raised as a unit to make the water shallower, so the wave 1725 ′ breaks even more abruptly, creating an even rounder concave in the cross-sectional profile of the plunging wave 1725 ′.
