The rotors can each comprise at least one blade arranged to rotate about a rotational axis, the blade is formed by a surface that extends between the internal and external conical helices, the conical helices each have a section that is reduced when Increase the radius of the propeller. The generally conical body surface may be conical, truncated cone or in any other way designed as a surface of revolution that generally has a growing or decreasing radius. On the other hand, these parameters can be varied alone or in combination as required to achieve the desired performance characteristics. The connection between the generator and any ring can be made with a simple gear or using a bearing wheel or some other means. In preferred embodiments, the blade extends between these and the outer ring and the inner surface are mounted to both.
In a particularly preferred embodiment the generators can be mounted mobile in parallel to the generally conical surface in order to allow variation of the rotational speed of entry to the generators by movement along the surface of the cone as discussed. The parameters discussed above, including the radius of the conical helix, the section of the conical helices and the relative increase in the radius of the internal and external conical helices that preferably go linearly along the length of the rotor.

The rotor therefore preferably includes internal and external surfaces that include the blades, which can generally generally internal and external revolution conical surfaces corresponding to the routes of the conical helices. Within this arrangement the rotors are both mounted for rotation around a single shaft and preferably mounted for counter rotation, that is, such that the first rotor rotates in the opposite direction around the axis of the second rotor.
The use of multiple generators of high efficiency, high speed, and low torque, mounted on the rotor with a surface that has a diameter that spans the length of the rotor, in which multiple generators are arranged to be connected to the surface in different diameters so that they run therefore different rotational speeds in relation to the rotational speed of the rotor are considered to be new and inventive in their own right, and therefore, seen from an additional aspect, the invention provides a rotor For generating electric power of fluid flow, the rotor comprises a surface that has a diameter that spans the length of the rotor, in which multiple generators are mounted to receive the rotational force of the surface movement in varying diameters Of the same. On the contrary, a non-linear increase in the internal and external radii r with the polar coordinate 0 provides a different shape, for example, the internal and external conical surfaces can be curved.

Figures 9A and 9B are perspective views of the two stage rotor apparatus of Figure 8 with the outer ring partially and completely omitted. Various generators can be placed around the periphery of a rotating outer ring in order to extract the maximum power and / or be placed in an internal central space of the rotor and extract power from the rotating inner ring. Various generators can be placed around the periphery of the rotating outer ring in order to extract the maximum power and / or be replaced in the internal central space of the rotor and extract power from the rotating internal peripheral surface. The connection between the generator and each ring can be made with a simple gear or using a bearing wheel. The external conical helix 5 is a helix formed on the inner surface of the outer ring 1 and forms a variable external radius ro of the blade 2. The internal conical helix 6 is a helix formed on the outside of the inner cone 3 and forms an internal radius variant ri of the blade.
Additionally, the operation of the rings of the generators 13 outside their operating range can be controlled and of course, all the generators can be disconnected if the two-stage turbine is overloaded in the flow of foreign fluids. Additionally, the connection between the pair of conical helices is not limited to being straight.

In this embodiment the pair of conical helices 5 and 6 are generated in a clockwise direction and form the design of the blades 2 in the manner discussed above. Man can also generate fluid flow directly or indirectly, for example, secondary fluid flows can be generated upstream or downstream from an obstacle placed in a naturally occurring fluid flow such as a dam in a river. For example, in a preferred embodiment the rotor is used in a turbine to generate electricity from tidal flows. In this case a subunit of the arrangement containing the rotor and electrical components can only be separated from the main installed structure that leaves the main installed structure in place. An alternate arrangement (not shown) would be to mount the two-stage rotor apparatus in a housing within a tube where the fluid flows. Figures 3A and 3B show perspective views of the rotor of Figures 1 and 2 in which the additional detail of the shape of the blades 2 can be observed.
Alternatively, the different curve or spiral shapes can be used for internal and external conical helices that produce a more complex blade shape. Dolor de cuello espalda y brazos . A preferred option is the use of an Archimedean spiral with a linear increase in the radius, which can be used to produce a rotor with a simple shape based on the truncated cone on the straight side. Thus, the rotors as described herein are used in preferred embodiments in a two stage rotor apparatus installed in a rotor housing. In the described rotors a solid surface joint of the flowing fluid body is formed by the pair of front and rear rotor blades and the inner and outer rings of the rotor. Also as shown in Figure 12, compartments 17 are sealed that can incorporate control pins for generators or flotation devices to allow the safe recovery of the two stage turbine to the surface for repair and service.
