The present invention relates to a rotor for aerogenerators and propellers, maximize energy of air flow (wind) to generate electricity.

The prior art windmill with sails and coil motor (see EN 2008512 C1), the Central sleeve which has two series of main radial spokes that have established rims, United with spokes stops-stretch marks. On the rims fixed helical blade oriented at an angle to the axis of the shaft. Each of the blades separated by length into several parts. The design according to the Russian patent is designed to improve reliability and increase power, strength and mobility, as well as simplify the design. While passing through the radius of the main spokes are only fastening rims parts and to transfer wind energy into rotational energy installed (on each wheel) of the scapula. However, this design of the rotor of the wind turbine is quite complex due to the large number of parts used, convenient to use and maintain. In addition, the use of multiple component parts leads to constant breakdown of the various compounds of the rotor, which can cause serious damage to the rotor and frequent stops wind is gregate for his service. Moreover, mechanical hinged connection of the rotor blade between a time could be reduced and lead to a decrease in the power output of the wind turbine.

The technical task of the present invention was the creation of the rotor for aerogenerators and propellers, which at least partially eliminated the disadvantages of the known wind turbine. Thus, the technical problem of the present invention is to provide a rotor for aerogenerators and propellers having a simple construction and providing efficient use of energy flow.

This problem is solved due to the fact that the rotor for aerogenerators and propellers having circular a cellular structure and containing a Central core or hub on which you are installing the inverter or motor, at least two tubular cylinder mounted coaxially with the Central rod according to the invention contains many blades, representing at least four parts, passing between every two adjacent tubular cylinders, connecting them to each other and forming together with them pipes having a cross-section in the shape of a trapezoid, parallel bases which are plots of the tubular cylinder, and lateral sides - passing through the RA is iusu details moreover, the pipe is curved along a helical line on its length around the rotor axis.

Preferably, the tubular cylinder with the largest diameter is at the entrance of the expansion in the form of a truncated cone.

Mainly, a tubular cylinder with the largest diameter is narrowing as bell in the shape of a truncated cone.

Hereinafter the invention will be described in more detail in the examples of its embodiments with reference to the accompanying drawings, on which:

When this tubular cylinder 1 are connected to each other by means of 2 parts. Details also connect the tube cylinders with the goals of the Central rod 3, which is the axis of the alternator. As shown in figure 1, portions of the tubular cylinder 1 between the parts 2 and parts 2 form a pipe with a cross section in the shape of a trapezoid. Figure 1 presents twelve pipes 5, formed by two outer tubular cylinder 1. Accordingly, ten pipe 5 is formed over the inner two cylinders 1, further inner pair of cylinders 1 forms an eight pipes 5, and the inner pair of cylinders 1 forms a six pipes 5. The tubes 5 are curved in its length along the axis of the rotor, as shown in figure 5. The outer tubular cylinder 1 with the greatest diameter according to the first variant embodiment of the rotor has an inlet extension 4 in the form of a truncated cone for more efficient air intake.

Figure 2 shows a front view of a second variant embodiment of the rotor according to the invention for screws having four tubular cylinder 6 mounted coaxially with each other. When this tubular cylinders 6 are connected to each other through parts 7. Details also connect the tube cylinders with a Central rod 8, which is the axis of the screw. As shown in figure 2, the sections of the tubular cylinder 6 between the parts 7 and parts 7 are formed of pipe sections in the form of a trapezoid. Figure 2 presents twelve pipes 10, formed by two outer tubular Qili is drama 6. Accordingly, ten pipe 10 is formed over the inner two cylinders 6, more inner pair of cylinders 6 forms an eight pipe 10, and the inner pair of cylinders 6 forms a six tubes 10. The tubes 10 are curved in its length along the axis of the rotor, as shown in Fig.6. The outer tubular cylinder 6 with the largest diameter according to the second variant embodiment of the rotor is narrowing 9 in the form of a bell in the shape of a truncated cone to minimize the square of the output air flow for the most complete selection of the kinetic energy of air flow.

All of these different parts can be achieved by traditional methods of connection, such as welding, riveting or screwing. The dimensions of the rotor aerogenerator can be changed in accordance with the required power. Structural materials, preferably metals, must be lightweight and resistant to corrosion. In addition, the rotor according to the invention can be made of alloys of high strength and lightweight materials, and plastic materials.
