Abstract

Windmill wing-system, persisting of wind-adjusting wing surfaces. The windmill wings are connected directly (indirectly), and when wind hits a wing surface, it rotates around its rotation arm, faces and catches the wind, while the wing surface in opposite side simultaneously rotates and becomes parallel with the wind direction, and insert minimal resistance, rotating against the wind direction. When the first wing surface has reached its maximum distance rotating the main windmill axel, away from the wind direction, the other wing surface is hit by the wind, it rotates around its rotation arm in windmills main rotation axel, facing and catching the wind pressure, and the circle starts all over, resulting in rotation of the main windmill axel.

Description

Title: Wind adjusting windmill wing system Description

This is a new windmill wing system with wings that adjust to the wind direction automatically by the wind direction and wind pressure when the wind blows.

The wind mill will consist of 2 or more sets of, our 2 wing set system, in order to catch wind from all directions, and to be more effective and have higher output.

Advantages of this new windmill wing system are as followed:

1- Since this windmill does not have to be guided or turned toward the wind direction, it is cheaper to maintain and build and does not need any systems to turn it toward the wind direction.

2- Because the wings are either moving with the wind or they are travelling like a

airplane wing(aerodynamically) parallel against the wind direction, the windmill is very quiet and will be experienced sound wisely, like a building or a tree.

3- The windmills wing speed is low, and the wings are seen easily specially by birds and therefore not dangerous for birds, hereby environmentally friendly.

4- The very simple structure form of the windmill means it is cheap to build, and

therefore the kilowatt price of the produced electricity (or other uses) will be very low. And since the windmill is cheap to produce, it will be feasible to use them in places with less wind as well.

5- Since the wings adjust them self by the wind pressure, there is no need for any

system to change the degree of wind attack angles on the wings

6- Since the wings are built of very hard materials and the turning speed of the

windmills main axel is low, it will be easy to build this kind of windmill resistant to very strong winds and storms, so they still can rotate and produce even when the wind speed is very high.

7- Since there are not many parts to maintain, the cost of producing and maintaining this kind of windmill, will be very low and everybody will be able to buy one and have it in the back yard or on top of their houses, also because the windmill is very quiet

8- There are stoppers/dampers either on the surface of the windmills main rotations axel or inside the windmills main rotation axel which protect the wings from turning too fast, chattering and breaking, when the wind is blowing strongly, hereby protecting the wings When the wind blows, it will be picked up by the wing which is nearest the wind direction. (Picture 1/6 and 2/6)

This wing surface is forced to turn and face the wind direction. Because of the wind pressure and rotation of this wing surface, will the wing surface on the opposite side turn parallel with the wind direction. (Picture 2/6 and 3/6)

Then the wing which is now facing the wind, pushes the windmills main rotation axel rotating. When the wing facing the wind reaches its 180 degree from the point it caught the wind and faced the wind, the other wing is in the position of catching the wind and rotating, facing the wind. (Picture 4/6)

We have shown wing stoppers and dampers, located on the surface of the windmills main rotation axel. These have the responsibility of dampening rotation speed and stop the wing rotating further on its path fixing the wing surface in optimal position, so the wing catches the maximum pressure of the wind, and at the same time does not turn too fast around its own rotations arm, which can result in damage to the wing. (Marked with B in the pictures)

Applications for patent on these breaking and damper system are sent separately.

These dampers can be placed either on the outside of the windmills main rotation axel or inside the windmills main rotation axel or a combination of both, inside and outside.

Explanations of nomenclature of all the pictures: A- Windmills main rotation axel

B- Wings turning-Break and dampening device which stop the wings to rotate further from this point and slowdown the wing rotations last degrees before stopping.

C- Wing rotation arm going in to the windmills main rotation axel, mounted on ball bearings in the windmills main rotation axel

F- Wing on one side of the rotation arm

G- Wing on the opposite side of the rotation arm

I- Rotation direction

K- Wings counter-weight side, showing the counter weights L- Wind direction

M- Wings rotation arm, illustrating inside in the wing

0- Windmill wings balance center point which is a little bit toward the wings tip, in order to have the windmill wing tips downward, when the wind mill is not rotating, in this case.

W- Area of the counterweight of the wing

Z- Area of the wingsurface, which controls rotation of the wing, facing the wind direction

Picture explanations Picture 1/6

The neutral position of the wings just before the wind starts to blow

Picture 2/6

The wind has hit the wing G and pushes this in to the place, which is facing the wind in order to catch the wind. The wing G starts to push the main rotation axel of the windmill rotating.

The wing F surface, rotates parallel to the wind direction and is travelling against the wind direction, persisting minimal resistance, and producing minimal sound

Picture 3/6

The wing G has turned ¾ of the circumference of the wings rotation circle and the wind is still pushing it, and the windmills main rotation axel is rotating.

Picture 4/6

The wing G has almost reached its maximum distance in the wings rotation circle circumference, from the winds direction point and the wing F is just to be pushed by the wind

After this the wing F is pushed by the wind pressure, facing the wind direction and the wing G will be parallel with the wind direction and the windmills main rotation axel will continue rotaing

Picture 5/6

This picture shows the counterweight side and the balance center point of the wing. In our case we have chosen to have the balance center point toward the wind catching surface of the wing. This will result in the wind catching wing part to be heavier and therefore when it is wind still this part will point downward. If the balance point of the wing is in the counterweight part of the wing, this will result in counterweight part pointing downward when it is wind still, where the wind catching wing surface will point upward.

We have chosen to show the counterweight outside of the windmill wing, in order to better be seen in the picture. This does not have to be the case and the counterweight wing side can be covered by material like the rest of the wing and can act as some wind catcher, as long as the main wind catching area of the wing, is larger than the

counterweight wing area.

Picture 6/6

This picture shows our wing system, with a shared common wing rotations arm. The system is not in the main rotations axel of the wind mill. This picture shows how the wings 2 sides are placed angle wise compared to each other, on the same rotations arm. The wings can be by definition connected, in the windmills main rotation axel by a cogwheel system, where there will be 2 wings connected by cogwheels in the windmills main rotations axel.

Claims

Claims:

A windmill wing system that consists of 2 (Or more) wing surfaces, which are placed in (Different) opposite sides of a shared main rotation axel. The wing surface of one side angels 90 degrees, compare to the wing surface on the opposite side (See picture 2). Wing flaps are connected and are in direct (Indirect) connection with each others. when the Wing surfaces are connected directly, by a shared rotation arm, the rotation of one wing surface results in rotation of the other wing surface (if there is indirect connection, it is via combinations of cogwheels that can be placed inside the windmills main rotation axel). In our drawings we are showing the direct shared axel which is the simplest

connection and the more practical one.

Turning one wing surface on its rotations arm, results in this wing surface catching the wind pressure, while the wing surface on the other side rotates parallel to the wind direction, so it persist minimal resistant rotating against the wind direction.

The windmills wings have counterweights, so the rotation of the wing surfaces by the wind, needs minimal wind pressure. The balance points of the wings are slightly toward one side of the wing, either the counterweight side or the larger wing surface side. The balance point of the wings, are located in the middle of the length of the wings, from the windmills main rotation axel

This kind of windmills can be used at sea, on land and on board of ships or balloons.

Furthermore they can be used on lines pulled by kites that hold them op in the air.
