Abstract

The present model is a wind turbine (1) with vertical axis. However, a high efficient wind turbine is acquired by reason of closing rapidly of the blowing wind part with the property of the one way opening and the being parallel to the ground of the wings (8). The wind turbine (1) drives a compressor (4) which supplies a storage tank (5) with compressed air which drives an air motor (7), which in turn drives a dynamo.

Description

SPECIFICATIONS
Wind Turbine with Air Motor and Vertical Axis Controlled with Air Pressure
The wind turbines are branched off as vertical and horizontal axis. The turbines with horizontal axis are excited by the propellers. The benefit range from wind power of the turbines excited by the propeller varies between 50 and 59%. The benefit range from the wind power of the wind turbines with vertical axis are lower than the turbines which excited with propellers. The efficiency of these kinds of turbines is between 30 and 35%. Therefore, the highest efficiency belongs to the turbines excited by the propeller in terms of the benefit range from wind power.
The cost of the turbines excited by propeller is too much. The most important reason is very high cost of towers because of holding upside of the dynamo. The spin mechanism according to the wind, the brake mechanism, the wing angles changing mechanism, the mechanisms which fix power with changing the wind speed causes the high cost.
The one with vertical axis is more acceptable in terms of low power. However, these turbines are not preferred since they are rounded by the difference of the pressure which the wind causes to the wings on every two side. Therefore, this motion results in the efficiency getting down.
There is the inverse proportion between the cost and efficiency. The given model is a wind turbine with vertical axis. However, a high efficient wind turbine is acquired by reason of closing rapidly of the blowing wind part with the property of the one way opening and the being parallel to the ground of the wings. The shape of the wing is designed for getting of maximum benefit from the power of the wind. It does not need any mechanisms such as the direction mechanism or being lifted of the dynamo because it is with vertical axis. In addition, the wings excite to the compressor not to the dynamo directly. The compressor controls the highest point of the pressure while protecting of the pressed air. The compressed air excites to the air motor and then the air motor excites to the dynamo.
This mechanism consists of the wings, the tube which provides the weight of the wings fix on the oil, a compressor with two pistons and an air motor. The advantages of these mechanisms are that; the dynamo doesn't need to be lifted, wing efficiency of the mechanism is very high, wing mechanism is able to be used also in the water, the mechanism doesn't have any direction mechanism, it isn't effected by wind blowing fast or slow as the direct proportional with the storage size because of the pressed air and continues to excite to the air motor. Consequently, the turbine has very low cost. The only disadvantage of this mechanism is that the noisy factor is higher than the other turbines.
The wings (1) are the high wings which are able to open\close with one way and assemble numerously, are parallel to the ground and have high exciting power. There is no power missing if the frames of the wings of this turbine are made of so heavy material. The mechanism of the wing rounds on the oil (3). The wings conduct the power to the compressor with the geared mechanism (2). The compressor with double pistons (4) is preferred since it is able to pump air in lower speed according to the screwed compressor. The geared compressors will be crunched below the 4 bars. According to the size of the compressor storage which is shown by (5), the turbine continues to excite at the windless time. In this mechanism, there is no necessary the brake mechanism when the wind speed increases and the mechanism which changes the wing angle. The air purging exhaust (6) fixes the air pressure. It is not affected by blowing fast of the wind and strengthens to the storage size when the wind blows slowly. Any of the motor with piston or fin is able to use as an air motor. In here, the finned type is preferred because of the low cost. When the propeller is used instead of these wings which designed for the wind turbine with vertical axis the cost is reduced again. Because this mechanism is not affected by the wind speed and strengthens in the low speed.
In the figures, the pieces are numbered and the meanings are shown below.

11- The bar which limits the angle of the fins at 90 degree
12- The bar for blocking dangle of the wings at wind turbine with high radius Explains of the parts at the figures:
1. Wings which are simplex, parallel to ground and has vertical axis. There are minimum three big wings which are attached to axis. Ideal numbers of wings are 6. If rise of power needed, the number of the wings has to be increase. Each wing binds the axis shaft and also these wings are connected to the top of the axis shaft by their ends. Each wing has moving fins. These fins are moving parts of wings which are between the 10 cm and 50 cm. The wings material, which is attached the axis shaft, is not important whether the material is light or not. On the other hand, the moving fins have to be made of very light material. Every wing's end connects the other wings which come after it. This makes them stronger against the high pressure of strong winds. The fins connected the top of the other fins to block passing the 90 degree angle.
2. The geared mechanism is designed for increasing the speed of wings.up to 10 times. We can mount big gear to the axis shaft, and mount small gear to the compressor. On the other hand mounting unlimited screw to axis shaft and mounting big and small gear to the compressor is possible too.
3. The best way to reduce the weight of wings and the shaft is putting the axis shaft's end side into a tube filed with oil. In this system the end side of shaft is in the oil but it does not touch the ground of mechanism. This system is necessary for high powers. For the small powers, the end of shaft ,which is pointed and has diamond, is putted into a half sphere shaped steel filed with oil is enough.
4. The compressor with two pistons is not compulsory it can be any compressor. The using of the compressed air in the wind tribune is the invention. Although the screwed compressor is very efficient if the wind pressure decries fewer than 4 bars the compressor will be crunched.
5. If the compressor holder is made of a heavier material and designed bigger than standards, the affect of wind to the system decries according to bigness of the holder.
6. When the wind speed is too high some of the air can not be used, in such situation the overly air flows out from exhaust. With the help of this mechanism, the system does not need to stop like other wind mills.
7. Air engine can be any system which can convert the air pressure to the motion. If the cost is considered, the fined type system is the most preferred type.
8. The moving fins made of ultraviolet proof and light materials.
9. The frame in connection to the fins which ensure to enfold according to the wheel account of the power by direct proportional with the distant to the axis.
10. The support which connects to the ending point of the frame at the back of every frame to bear with the frame of the wind turbine according to the powerful wind. 11. The support which connects the frames and thin and flexible material to each other to fix the motion of the fins at 90°.
12. The support which connects to the axis and the frame columns of the turbine to hinder to impend to the down.
