  • the present invention relates to a wave generating apparatus.
  • the invention relates to a wave generating apparatus that includes at least one submerged lateral surface that mimics a shore gradient in use.
  • a wave generating apparatus comprising:
  • a forwardly disposed water displacement body adapted to generate a wake as the wave generating apparatus moves through a body of water
  • At least one lateral wing extending outwardly from a lower portion of the wall, wherein an upper surface of the lateral wing defines a wave generating surface having a positive gradient extending outwardly from the wall which, in use, acts as an artificial shore line whereby waves are generated from the wake generated by the water displacement body.
  • the above components of the wave generating apparatus may or may not be physically connected.
  • the water displacement body and the wall may be physically connected to one another, or the wall and the at least one lateral wing may be physically connected to one another, or both.
  • the at least one lateral wing is independent of the water displacement body and is not directly or indirectly connected thereto, and wherein the at least one lateral wing, in use, is adapted to travel through the body of water at the same speed as the water displacement body and at a fixed position relative to the water displacement body.
  • the at least one lateral wing comprises a pair of opposed lateral wings, one extending from each side of the lower portion of the wall.
  • the opposed lateral wings extend outwardly and rearwardly from the lower portion of the wall.
  • the opposed lateral wings may define substantially parallelogram wave generating surfaces.
  • the positive gradient defined by the wave generating surfaces may be linear, that is the wave generating surfaces may be planar, it is envisaged that in a preferred embodiment the positive gradient is substantially sinusoidal. That is, the wave generating surfaces are preferably curved, partly in one direction and then in the other direction with a relatively small amplitude and relatively large wavelength.
  • the opposed lateral wings extend from a lower portion of the longitudinal wall. Preferably, the opposed lateral wings extend from a lower edge of the longitudinal wall.
  • the form of the water displacement body is not particularly limited.
  • this may be of a hull-like form, a block or other suitable form.
  • the water displacement body is in the form of a wedge including a substantially planar upper surface, a declined planar lower surface that forms a forward edge with the planar upper surface, two opposing sides extending between the planar upper surface and declined planar low surface, and a rear wall.

  • the water displacement body and the wave generating surface are moved through the body of water at the same speed and at a fixed position relative to one another.
  • the velocity of movement of the wave generating apparatus through the water will be dependent on the waves desired to be generated and the related dimensions of the wave generating apparatus.

  • the speed has to increase by the square root of two, which is 1.414.
  • the draft of the wave generating apparatus has to be doubled, as does the distance from the water displacement body at which the wave(s) will break. As such, the physical parameters are increased in a linear fashion while the speed increases by the square root of the multiplying factor.

  • the present invention provides a wave generating apparatus.
  • the invention relates to a wave generating apparatus that includes at least one submerged lateral surface that mimics a shore gradient in use.
  • the wave generating apparatus includes a water displacement body 11 , a longitudinal wall 12 extending from the water displacement body 11 and a pair of opposed wings 13. As illustrated, these components are connected to one another. However, as discussed above, this is not necessarily the case and each component may be independently mounted.
  • the water displacement body 11 is designed to cut through the water, generally at or just below the surface of the water.
  • the water displacement body 1.1 is in the form of a wedge, including an upper planar surface 14 and a declined planar lower surface 15 that forms a forward edge 16 with said planar upper surface 14.
  • Two opposing sides 17 extend between the planar upper surface 14 and the declined planar low surface 16, and a rear wall 18 completes the wedge.
  • the upper planar surface 14 of the water displacement body 11 is contiguous with an upper surface 19 of the longitudinal wall 12.
  • the longitudinal wall 12 substantially extends along the length of the wave generating apparatus 10 and is centrally disposed relative to the water displacement body 11.
  • the longitudinal wall comprises a neck portion 20 that extends from the rear wall 18 of the water displacement body 1 .
  • a lower surface 21 of the neck portion declines to a position 22 where the pair of wings 13 extends from the longitudinal wall 12.
  • the pair of wings 13 extend from a lower edge 23 of the longitudinal wall 12.
  • the pair of wings 13 extend outwardly and rearwardly from the longitudinal wall 12.
  • the wings 13 take the form of a parallelogram extending in an opposing manner from each side of the longitudinal wall 12.
  • a wake emanating from the water displacement body 11 passes over an inner portion 24 of the wings 13, representing a portion of the wings that is relatively deep within the body of water, through to an outer portion 25 of the wings 13, representing a portion of the wings that is relatively shallow within the body of water.
  • the wings 13 illustrated are curved or substantially sinusoidal in. nature, although they could also be linear (i.e. planar). As such, depth of water at the inner portion 14 of the wings gradually decreases initially, ensuring that wakes generated by the water displacement body 1 1 do not encounter any drag until they have advanced clear of the water displacement body 11. As the depth of the water decreases, approaching the outer portion 25 of the wings 13, this forces the wakes to break thereby generating waves. It is envisaged that the wings 13 may also be angled in some instances to obtain suitable break characteristics of the waves.
  • the profile or thickness of the wings 13 is minimised, at least in the direction of movement of the wave generating apparatus 10 to avoid any negative impact associated with drag. That is the profile of the leading edge of the wings 13 is minimised to achieve minimal displacement of water on movement of the wings 13 through the body of water.
  • the wave generating apparatus 10 may be moved through the body of water using, for example, a system including tracks or rails. Such a system may be driven by any means as would be readily appreciated by a person of skill in the art.
  • a cable may be employed to impart movement to the wave generating apparatus 10.
  • the wave generating apparatus 10 may be mounted on the cable, or other mechanism, by any suitable means. It may be that the wave generating apparatus can be towed by a powered vessel. All such embodiment are within the ambit of the present invention.
