The radial flow component is useful in that the two opposite ends have a small section towards the rotor blade and therefore transfer flow between the two rotors which is more effective when the flow has a radial component, as well as a axial component. In a preferred embodiment the rotor has an opening in the small diameter end of the rotor that is arranged for axial fluid flow. The generators 13 are driven by the internal revolution surface of the internal cone 3 of the rotors 7, 8 by the appropriate gear. 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. The internal and external conical helices can both increase in radius in the same proportion, such that the conical surfaces are generally parallel.
The connection can be curved, for example, a concave surface can be used to increase the surface area along the surface of the rotor blade with special shape in order to disperse the resulting hydrodynamic forces over a larger larger area and reduce internal tension, Similarly the pair of conical helices are generally aligned axially for simplicity but can be slightly misaligned in order to change the surface characteristics of the conical helices in a beneficial way. The surface may be a generally conical surface or a stepped surface, as described above. A large series of magnets will be necessary to directly generate the correct frequency to direct the connection to a typical electric grid.
The formed stator and rotor can be configured in any suitable way to produce alternating current (AC) or direct current (DC) in an efficient manner. Preferably the rotor has a large diameter opening that is also perpendicular to the rotational axis of the rotor. Internally, the rotor therefore has one or more flow passages formed between the front and rear blade surfaces, the outer ring and the inner surface. 4 longitudinal due to the external variant radius. A feature of this form is that the linear velocity of the ring 3 varies along the longitudinal axis 4 due to a variant external radius. For the reasons discussed above, it is evident that an underlying spiral that has a faster change in the internal and external radius r with the coordinate 0 polar induces a faster rate of change of the momentum that necessarily results in an increase in the force of hydrodynamic reaction.

The internal conical helix may increase in radius at a slower rate than the increase in the radius of the external conical helix in order to reduce or restrict the hydrodynamic reaction forces and torsional forces produced by the rotor. This has the effect of reducing the changes in the velocity components and therefore the mass flow is constant, the hydrodynamic reaction forces produce less. In this case, the cross-sectional areas in the first and second arbitrary cross-sections in the rotor increase in a constant proportion and because the mass flow is constant, the differences in speed and in this way the hydrodynamic reaction forces produced are constant. Entrenar con dolor de espalda . When the radius of the pair of conical helices increases to a greater or lesser extent to form a pair of non-parallel conical helices, this has the effect of changing the proportion in which the cross-sectional areas in the first and second arbitrary cross sections in the rotor increases.

1 is a rotor where the radii of the pair of conical helices increase in the same proportion to form a pair of parallel conical helices. The fixed motor mounts 12 are attached to the fixed shaft 11 within the rotors 7 and 8. This provides a mounting area for multiple generators 13 of high efficiency, high speed low torque. Because the rotor in this case can be a rotor with rotating peripheral internal and external rings, large surface areas are available for connection to multiple high speed and low torque generators. Said external force can be experienced if it is installed transversely or longitudinally on board a ship or some other mobile object such as a train or a car creating transverse and / or longitudinal movement. Figure 13 illustrates an arrangement with a pair of two-stage rotor apparatus installed on a type of structure tower for use on a seabed.
Figure 15 is a graph illustrating the effect of increasing or reducing the relative radii of the pair of conical helices to form a pair of conical helices not in parallel. For example, the rotor housing can be designed exclusively to house the rotors and provide support via mechanical bearings, magnetic bearings or some other type of active or passive bearing system that allows the rotors to spin freely with little friction. To allow the rotation of the blade, it can be mounted on the outer ring and / or the inner peripheral surface, which are then mounted for movement, for example, by means of bearings and a fixed shaft. The conversion of energy from gas flows such as air currents, ie wind power, is a well developed technology.

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. This is a rotor where the radius of the pair of conical helices does not increase, that is, this is a rotor based on a cylindrical helix and not a conical helix. However, the radius ri of the internal conical helix 6 increases to a lesser extent than the radius ro of the external conical helix 5 to therefore form a pair of non-parallel conical helices that are further separated at an end of larger diameter rotor than a small diameter end of the rotor. Alternatively, the different curve or spiral shapes can be used for internal and external conical helices that produce a more complex blade shape.
However, it may be advantageous to adjust the rotor performance by having a different index of increase in diameter for the internal and external conical helices. Because the generators of 13 in this embodiment are mounted on a fixed motor assembly 16 the generators 13 can be installed as rings of generators that can be engaged or disengaged as required in different locations along the longitudinal axis 4. The rings of the generators 13 can be engaged or disengaged by section-by-section motors activated by wired or wireless monitoring equipment and / or CPU such that the two-stage rotor apparatus is capable of responding to changes in the rotation speed. 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.

The tube can be installed within the waterways of a dam or a hydropower station or a tidal dam Alternatively, if it can be within a liquid enclosed current system consisting of two liquid reservoirs connected in such a way that the transfer of liquid from one deposit to the other. In preferred embodiments, the method comprises selecting the rotor characteristics based on the desired rotor performance characteristics. The rotor housing can be used to improve the performance of the rotors.
Three identical rotor blades 2 are shown in the rotors shown in the figures. Dolor de rodilla que se extiende hasta el tobillo . Permanent electromagnets can be mounted on the outer ring of the rotor and on the inner side of the rotor housing for this purpose. The connection between the generator and each ring can be made with a simple gear or using a bearing wheel.
For a low-speed fluid flow the generator connection point can be made at the highest linear speed end, that is at the larger diameter end of the rotor. The design of the rotors and the blades can be tuned to a particular application through the variation of the parameters as described above. 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. Figure 14 is a graph illustrating the effect of varying the ratio of the maximum external diameter C of the rotor to the external diameter mm. The blade or blades are preferably formed as surfaces generated by straight lines between points in the internal and external conical helices at the same longitudinal distance along the direction of the rotational axis of the rotor.

Figures 2A and 2B describe the rotor of Figures 1A and 1B with the outer peripheral ring 1 partially concealed for clarity. The apparatus can therefore take the form of a tidal turbine comprising the rotor apparatus. Figures 7A and 7B show the opposite variant in which the helical section is reduced by a larger index, resulting in a rapid index of helical frequency increase. This presents a significant advantage, in that a complicated gearbox does not require that it represents a significant saving in economy and complexity. In summary, the preferred embodiments described herein provide a low-field complexity of the two-stage rotor apparatus that is ideal for the generation of tidal flow electricity. 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.
