A cooling system for a wind tunnel is disclosed. The heat exchanger of the present disclosure is formed as a turning vane in an airflow duct of a re-circulating wind tunnels. The individual vanes are formed from extruded aluminum with coolant fluid channels running continually down the length of the vane. One or more channels can be used, depending on the application of vane and the cooling capacity needed. The exterior of the vanes are formed in an airfoil shape to efficiently turn the air flow the desired amount in a manner well known in the art. The turning vanes are connected to a fluid supply with single piece connectors that removably attach to the turning vanes. In the depicted embodiment the connectors are attached with screws. In the depicted embodiment the connectors are formed as a single piece in a two-piece injection mold.

Wave generator system (1) for generating waves in a mass of water (2) for leisure or sporting use, comprising a wave dissipating shore (6) capable of avoiding the formation of rebound waves. The shore (6) has a shore floor (7) with a decreasing height towards the floor (3) under the mass of water (2), a permeable shore ceiling (8) and a plurality of inner compartments (17), each compartment (17) including one or more barriers (22) that offer resistance to the passage of water in a direction towards the mass of water (2) and that leave a water passage space (24) that allows the passage of water in the direction of the mass of water (2). The wave absorbed by the shore (6) loses energy by moving through the compartments and returns to the mass of water (2) due to gravity.

The mobile sheet flow water ride apparatus of the present invention utilizes a rigid inclined structure. Ride surfaces, aisle surfaces, and surround fences are covered with protective inflatable air cushions. The ride apparatus of the present invention has non-retractable transport wheels and uses a multitude of adjustable jacks to take the load off the transport wheels and support the ride apparatus. The ride apparatus utilizes a 15,000 gpm double-suction pump driven by a 460-horsepower diesel engine that is transported in its own trailer. Water is pumped from a main storage tank through a horizontally-oriented nozzle that 2.438 meters wide and 6.35 cm high at supercritical speed. The water rushes up the slope, over a berm at the top of the slope, and back into the main storage tank through a square main return grate.

A rotatable sprinkler comprises a base with a continuous curved surface and a rotation element disposed rotatably and relatively to the base. The rotation element has an outlet that connects to a water source. A decorative unit is disposed on a support, part of which is located on the rotation element and the free end of which is in contact with the continuous curved surface of the base. Therefore, the decorative unit may rotate relatively to the base, or move up and down when the free end of the support is pressed against the continuous curved surface.

A wet play structure including a non-harnessed course and a harnessed course. The wet play structure can be located in an amusement park. The non-harnessed course and the harnessed course can be completely, or partially integrated to increase interaction between users. The wet play structure may include an elevated path configured to allow a user to traverse the elevated path. A track is configured to connect to a harness worn by the user while the user traverses the elevated path. In one aspect, the wet play structure may include a fluid conduit configured to transmit water onto the user while the user traverses the elevated path. In one aspect, a pool positioned beneath the elevated path and configured to contain water.

A water toy comprising a foam tube having a first end, a second end and a body therebetween, an optional seat positioned on the body, a first feature attached to the first end, and a second feature attached to the second end, the first and second features being aesthetic and/or functional and/or a combination of the same.

An apparatus comprises a wave generator configured to move water on a front side of the wave generator to generate a surfable wave and a displacer configured to move in synchronization with the wave generator, the displacer to displace water on a back side of the wave generator to compensate for water elevation changes on the back side of the wave generator that would occur in the absence of the displacer.

The present disclosure provides a water play feature that creates a laminar water jet stream, or multiple laminar water jet streams for interaction and display in a water park.

The invention discloses a system for forming an artificial wave (W) in a water environment, which comprises a pulling apparatus (6), a pulled apparatus (10, 10a, 10b, 10c, 10d) and a pulling arrangement (11), wherein the pulling apparatus (6) comprises a power pack (12) and the pulled apparatus (10) comprises a wave-forming profile (13), wherein the pulling arrangement (11) comprises at least two pulleys (14, 15) and at least one rope or line (16) provided at or via both ends of the pulled apparatus (10) and further via the pulleys (14, 15) for providing the movement of the pulled apparatus (10) between a first pulley (14) and a second pulley (15). According to the invention, the wave-forming profile (13) comprises at least two wings (1, 2), of which at least one wing (1, 2) is mainly transverse relative to the direction of advancement (A) of the pulled apparatus (10, 10a, 10b, 10c, 10d).

An amusement park system in accordance with present embodiments includes a ride vehicle configured to move along a path, an aquatic portion of the path defined by a water flow path, and an aerial portion of the path defined by a track configured to support a bogie. The ride vehicle is configured to freely float and move along the water flow path in response to currents of the water flow path. The ride vehicle is configured to be carried along the track by the bogie.
