The invention relates to wind and hydropower and for wind and hydraulic motors with a vertical axis of rotation.

Known for "Rotary engine with a vertical shaft rotation" (patent RU №2263815, F03D 3/00, publ. bull. No. 31 dated 10.11.2005,) containing the rotor, in which the working bodies are the blades made in the form of part of a hollow sphere or part of a hollow cylinder, mounted on a vertical shaft, the ends of which are mounted upper and lower bearings located respectively in the upper and lower bearing housings, while it has the support of the farm, consisting of at least three poles connected in one hard a constructive site upper and lower crossbeams attached respectively to the upper and lower bearing pads with holes in the center, and to the reference sites coaxially with holes attached bearing housing upper and lower bearing so that the rotor top and bottom ends of the shaft placed on them by upper and lower bearings mounted in bearing housings and placed inside the supporting farm between the reference sites, with the possibility of rotation.

The disadvantages of this design are

- low coefficient of performance (COP), as the area of the blades, engine torque, equal to the square of the blade, to prevent the soup rotation, as the rotation occurs because of a difference of streamlining forms;

low reliability and high material costs, as if a strong wind for the same and invariant square of the blades, located at both ends of the vertical shaft, all the energy acts on the shaft, to exclude such effects require large expenditures to increase hardness and metal construction.

Also known Turbine wind turbine" (patent RU №2009371, F03D 3/00, 3/06, publ. 15.03.1994 g)containing a Central vertical axis with the hub and fixed thereto concave wings pivotally mounted on the last vertical blades, each of the wings provided with a horizontal wheel arches, the Central one of which is rigidly fixed, and the top and bottom made in the form of movable sectors that are installed in the overlap with the working surface of the wing.

The disadvantages of this design are

- reduced efficiency, since the area of the blades installed on curved wings and preventing rotation of the engine is relatively high;

- the design complexity, low reliability and high material costs, as a large number of mating parts;

- reduction of efficiency because of the instability associated with the onset of turbulence (the occurrence of turbulences) blown on the Oka air, especially wind direction at the time of closing or opening of the blades;

- occurrence of turbulence flows with a slight linear speed (1.5 - 2 m/s).

Closest to the technical essence and the achieved result is "Turbine for power generation" (patent RU №2270932, F03B 17/06, F03D 3/00, publ. 15.03.1994 g) incident on the side of the flow of water or air, comprising a shaft, a ball placed at the front, around which in radial directions between the supports, strictly and properly fastened with the shaft, placed the blades can be rotated limited to latches, while the blades are made flat with rounded long edges and placed around the shaft in at least two directions at intervals around the edges, and the rotation of the blades is limited by two latches, and the so formed layer turbine is repeated along the length of the shaft with a uniform angular spread, this support can be in the form of radial consoles with an aerodynamic profile cross-section, and the retainers can be made retractable into the body of support in excess of the force of pressure of the blade bagged the spring force holding the latch in position.

The disadvantages of this design are

- reduced efficiency, since the area of the blades, etc which prevent rotation when the rotation of the turbine, quite large due to the presence of double clamps and flat blades;

- reduction of efficiency because of the instability associated with the onset of turbulence (the occurrence of turbulence) in the blown air stream, especially wind direction at the time of closing or opening of the blades;

- occurrence of turbulence flows with a slight linear speed (2-2,5 m/s), i.e. at the ends of the supports more turbulence, which limits the scope for effective use.

The technical task of the invention is to create an optimal and simple turbine with a vertical shaft rotation, allowing more to operate stably at high linear speeds and gusts of wind with higher efficiency, due to the blade design.

The technical problem is solved by a turbine with a vertical shaft rotation containing the hinge is placed on the rack shaft is rigidly and properly bonded with him and supports placed between the supports vanes are mounted on the axes can be rotated limited to two catches and supports are placed in at least two directions to form the rows.

What's new is that the blades are made of a closed elastic material, tightly covering without the possibility of axial displacement thickness in the axis and biased the left from the axis a hard edge.

New is also that the blade is provided with lugs, the locking elastic material of relatively thickened axis.

New is also the fact that it is equipped with extra rows of poles with blades that are installed above and/or below the first row.

Figure 1 shows a diagram of a wind turbine cross section of a number of blades, top view.

Figure 2 is a view of the blades under the influence of the flow of air or liquid.

Turbine with vertical axis of rotation includes a shaft 1 (see figure 1), the hinge is placed on the rack (not shown), around which the radial directions between the supports 2, strictly and properly fastened to the shaft 1, the blades 3 axis 4 can be rotated limited to two clamps 5 and 6. Blade 3 (see figure 2) is made in the form of a closed elastic material 7, densely covering without the possibility of axial movement by stops 8 thickness in the axis 4 and is pressed by a spring wire 9 from the axis of the hard edge 10. Elastic material 7 can be fixed relatively thickened axis 4. Support 2 (see figure 1), which are the axis 4, is placed in at least two directions relative to the shaft 1, forming a number 11 blade 3.

At the same time to increase the size and uniformity of rotation without increasing the length of the supports 2 turbines of similar very near to the 11 pillars with 2 blades 3, installed on the turbine above and/or below the first number may be more than one.

The turbine operates as follows.

Under the action of the stream, regardless of its direction) gas (air) or liquid (water) blade 3 (see figure 1) on the 4 axes are rotated between the clamps 5 (open state), located at a distance from the supports 2 and 6 (the closed state), located in the immediate vicinity of the supports 2). When in the closed state the total area of the blades 3, which affects the flow exceeds the total area of the blades 3, which is open at the other end from the shaft 1 in the opposite direction. In the result due to the difference of the efforts exerted by the flow in opposite directions, a support 2 with the blades 3 are rotated around the shaft 1.

Due to the fact that the blade 3 (see figure 2) is made in the form of a closed elastic material 7, densely covering without the possibility of axial movement due to the stops 8 thickness in the axis 4 and is pressed by a spring wire 9 from the axis of the hard edge 10, the blade 3 has a tear drop shape 3' (see figure 1) in the cross section in the free state or even the impact of the stream on both sides, when the blade 3' is located between the tabs 5 and 6. This form of blade 3' disposable towards the flow axis 4 has the lowest coefficient of resisting film to prevent the effect of the flow (in practice, the coefficient of resistance With x≈0,08-0,12), while the turbulent eddies generated by the blades 3, minimum. To prevent displacement of the elastic material 7 in the transverse direction relative to the thickened axis 2 it can be fixed relative to the axis 4.

Supports 2, which are the axis 4, is placed in at least two directions around the shaft 1 at one level, form the number 11 blades 3.

To increase the area and uniformity of rotation without increasing the length of the supports 2 turbines of similar series 11 supports 2 with vanes 3 that are installed on the turbine above and/or below the first number may be more than one. That maximizes removed from the rotating shaft 1 power (for example, when using the generator, gearbox and so on), without increasing the length of the supports 2, in order not to increase the linear speed remote from the shaft 1 of the blades 3 and, therefore, not create them parasitic currents flow and inertial effects on the blades 3 (as the weight of the blade is not zero, and the higher the speed, the higher inertia), resulting in lower efficiency of the turbine (in practice up to 30%). The more dense stream and/or below the speed of its flow, the longer can be the support 2 without generating spurious turbulence (eddies) flow remote from the shaft 1 the blades 3.

As the main weight of the blades 3 is concentrated in the thickened OSI, the inertia of its construction when turning low, which also has a beneficial effect on the efficiency of the turbine and allows the use of efficient turbine with anchorage length 2 15-20% greater than analogues with flat blades.

A side effect of the flow on the blade 3 front (windy) side (see figure 2) is bent in the form of "sails", allowing you to more effectively use the power of flow, even when the blade is 3" was in the open state, as its action is similar to action of the sails of the ship, moving tacks against the wind. In practice, the turbine is started to rotate at a flow rate of two times lower than when using carnal blades. After you install the blades 3' along the stream she immediately took a tear drop shape in cross section by squeezing the edges 10 (see figure 2) spring wires 9. This design of the blade 3 has enabled us to effectively work on linear speeds, almost exceeding counterparts.

In practice, as the elastic material 7 of the blade 3 used several options when exposed to side-stream:

first, closed-loop strip of plastic, as a result, only the front side of the blades was bent under the action of a stream;

secondly, hermetically sealed plastic, with an internal cavity (Fig. not shown)filled with air under the action of persons who howl side filled the air cavity was bent back, the opposite front side of the blades 3;

thirdly, the closed-loop bandwidth is slightly permeable to the flow of material (dense fabric impregnated polymers), under the action of passing through the front side of the stream has bent the back side of the blade 3, to a greater extent than in the second embodiment;

fourth, the closed-loop bandwidth is slightly permeable to flow only inside the material (fabric with a long NAP, inward), under the action of passing through the front side of the stream has bent the back side of the blade 3, to a greater extent than the third option.

Studies have shown that the higher the curvature of the rear part of the blade 3, the higher the velocity of the stream flowing along it, and the greater the force (according to the Bernoulli law), directed perpendicular to the rear part of the blade from it (similar to the effect of "lifting force" on the wing of the plane). The higher the flow rate, the greater this effect is.

Based on the above, the higher the average flow velocity, the greater must be the curvature of the back side (on the basis of alternative designs) blades 3 for more efficiency of the turbine.

When using two clamps 5 and 6, the difference between the effort exerted by the flow in opposite directions, where the support 2 with the blades 3 are rotated around-ear, closed the g shaft 1, less significant than the designs with one latch 6, and the design of the blades 3 eliminates the negative effect from it. All this together allows the use of a turbine on a moving platform (Fig. not shown).

The design of the proposed turbine with a vertical shaft rotation is simple and allows you to work effectively regardless of the speed and gusts of wind, region and place of use, including on mobile objects with an efficiency of at 10-16% higher than that of similar structures.
