The above described analyses led to the development of the devices that harvested energy from omnidirectional flow input as described in the PCT patent applications published as WO 94/10029 and WO 96/28657. Novel blade assemblies that have resultant forces produced thereon when placed in flows of fluid, particularly turbulent flows such as those experienced in wave environments, are described in WO 94/10029. The assemblies described therein are suitable for both linear and rotary applications, and have been successfully applied to both applications during comprehensive testing. The present invention provides not only solutions to the above detrimental effects, but also introduces specific advantages in terms of allocated buoyancy, which in turn provides numerous opportunities for completely novel solutions for both marine craft, propulsion, and/or payload assemblies, and wave and/or tidal crossover power generators. Although the pivot axis of the first blade is shown in the accompanying drawings as being vertical in both front and side views, it may alternatively be angled in the side view to utilize the buoyancy force to act as a spring means to centralize the blade.
As shown in the accompanying drawings, in particular in FIG. The centre of buoyancy CoB is above and behind the pivot axis when in the neutral position shown in the lower diagram. The second change is that the pivot axis for the horizontal blades has to be positioned directly above the centre of negative buoyancy, not below as in the positively buoyant case. This set of blades is connected to a support (103) to form the blade array (100). One or more such blade arrays (100) can be incorporated into a variety of different types of energy conversion apparatus. 4. Analgesicos para dolor de espalda . The prior art blade array (100) includes a plurality of rigid or semi-rigid blades (101) which are of generally planar shape and are interconnected along their inner edge (102) so that the blades combine to form an integral set of blades.

In a particularly preferred embodiment, the first blade includes a forwardly-inclined pivot axis, such that the centre of buoyancy rotates on an inclined plane, always seeking to return to the highest point in the orbit. The second blade that responds to vertical movement is pivoted in the horizontal plane towards its forward edge by pivot means that, in one preferred embodiment, is formed integrally with the vertically pivoted blade. In a preferred embodiment of the invention, the second blade is constructed so as to exhibit positive buoyancy.

The buoyancy characteristics of the blade assemblies described in the prior published patent applications discussed above are simply not addressed in those documents. The reason for this is that if there are many definable ‘cells’ impacting on a single blade at any one time, then cells containing opposing flow vectors will cancel each other out, reducing the net thrust on the blade surface. By contrast, one of the main objectives of the present invention is to combine two of the above essential elements of a marine craft, such that the buoyancy means also provides the propulsive means, with commensurate savings in complexity, weight, and therefore costs.
In this particular embodiment, the pivot axis of the pivot means (308) is inclined, so that the plane of rotation PoR is also inclined. This pitching and rolling also means that wave-powered devices attached to the hull form may be disadvantaged since the movement of the water relative to the hull form is lessened by the hull form moving in sympathy to the wave. In all cases, wave motion is created when water is ‘pushed’ to form peaks in response to the motivating force. The first blade that responds to lateral (horizontal) movement is pivoted in the vertical plane towards its forward edge about a pivot means (8), and moves laterally in response to water flows containing a lateral component. The first blade that responds to lateral (horizontal) movement is pivoted in the vertical plane towards its forward edge, and moves laterally in response to water flows containing a lateral component.
5, the edges of both blades are curved.
Then, as the stone moves on downwards, the surrounding water has to return to the void created by the sinking stone. Their eventual demise is a product both of the increasing circumference of the circular form of the wave (whereby it can only contain a diminishing amount of the original energy that produced it), and the frictional force within the water particle movement, which is converted into heat. This does not change the essential principles of the inventive concept, whereby separately pivoted planar blades operate against spring means in both horizontal and vertical planes simultaneously. 5, the edges of both blades are curved. Multiple arrays of wave propulsion modules according to the present invention may be employed in both linear and rotary applications. The trajectories of water particles in such conditions may best be described as both chaotic (non-predictive) and omnidirectional.

The above analysis of wave motion is a key element in understanding why it is necessary for any device that is designed to capture and convert the energy from wave motion into useful energy to deploy elements in both the vertical and to horizontal planes, so that it achieves maximum efficiency.

The to advantage of providing positive buoyancy only to the first blade is to ensure that the buoyant force is transmitted through the pivot means to the remaining structure above the water, without influencing the lateral positioning of the blade itself, which is only responsive to both the wave flow input and the spring means return force. The first individually-pivoted substantially planar blade (204) is positioned in the vertical direction and is pivoted in the vertical plane towards its forward edge about a pivot means (208). This first blade responds to lateral (horizontal) fluid flow, with the blade being deflected to port or starboard of its original neutral position. The majority of such devices have focused on capturing the energy contained in the movement of water in the vertical plane. The blade then acts like a weighted pendulum, and always seeks the lowest position, with the blade plane horizontal.

A blade constructed to be negatively buoyant tends to sink. The first blade is preferably constructed so as to exhibit positive buoyancy. FIG. 3 shows the disposition of a horizontal blade which utilises a pivot centre which is directly underneath the centre of buoyancy of the blade. FIG. 2 shows a first embodiment of an individual wave propulsion module for use in the linear propulsion device of the invention. 1 shows an exemplary linear propulsion device of the invention including an array of multiple wave propulsion modules.

Such a large range of end uses dictates that a large range of materials may be employed in the construction of the linear propulsion devices of the present invention. It should be appreciated that features of these embodiments may be variously separated or combined within the invention. Infección de orina y dolor lumbar . Tidal currents, and/or seabed topography may further modify such wave motion.

According to one preferred embodiment of the invention, the first blade is provided with pivot means that is inclined forward at the top of the pivot, such that the orbit of rotation of the blade is on a forwardly-inclined plane, thereby allowing the centre of buoyancy to provide a return force when the blade is deflected by lateral flows. In this embodiment, the buoyancy of the first blade is of a sufficient force means such that it restricts the blade’s radial movement about its pivot axis. In a preferred embodiment of the invention, the first blade is provided with limiting means comprising spring means. In a preferred embodiment of the invention, the second blade is provided with limiting means comprising spring means. When there is an incoming fluid flow having a component in the vertical plane, the blade is deflected as shown in the upper diagram in FIG. When a flow interacts with either the first or the second planar blade from a vector that is not co-planar with the blade, it is forced to change direction as it interacts with the blade surface.
Since the centre of buoyancy will always seek the highest point on the orbit of rotation, this acts as a return force when the first blade is deflected laterally. In an alternative embodiment of the invention, the first blade is provided with limiting means by means of the buoyancy of the first blade. Dolor de espalda baja al agacharse . In a preferred aspect of the invention, there is provided a pair of substantially planar blades, a first blade set in the vertical plane, when in use, and a second blade set in the horizontal plane, when in use. The first is that the pivot axis of the vertical blade has to be inclined backwards at the top, not forwards. Incorporating positive buoyancy into the second blade in addition to the first blade has the added advantage of contributing to the overall buoyancy of the device. In this embodiment, the centre of buoyancy acts directly through the pivot axis, at a right angle.
