Abstract

Fluid stream acts on construction of horizontal air turbine in the way that support on which there are stabilizer and rotor of turbine with deflector is turned in position of the smallest resistance that at the same time allows use of fluid energy. This position of support protects the blade in reverse shiftflower zone) with simultaneous acting of thrust force of fluid on open blades. Horizontal air turbine comprising a support on which are mounted a stabilizer, a turbine rotor and a deflector. By the action of the fluid stream on the stabilizer the airturbine is turned in the position of the smallest wind resistance allowing at the same time the use of fluid energy. The deflector protects the turbine blades rotating against the wind while simultaneously allowing the wind to act on the open blades to recuperate the fluid stream energy.

2)TECHNICAL PROBLEM

Transformation of wind energy inio electric energy.

S ICONTEMPORARY CONDITION OF TECHNICS

Windmills are currently used. The characteristic of these windmills is that the blades rotate vertically to the direction of fluid movement respectively the wind.Turning moment is produced by curving the blade so that rotation is a resultant of fluid force and resistance of working area(curving). Disadvantage of these windmills is that the blade during rotation cuts the line of fluid with very great resistance and utilization coefficient is very low.The blades are exposed at the same time to thrust force and resistance force resp.the same force produces both working effect and resistance.This rotation also produces very strong sound vibrations why they can not be used near the settlements, causing considerable loss in transmission of electric energy by the distance.The known technical solutions have not qualitatively solved the problem of changing the wind direction and they are used mainly in places where the wind has costant direction and course during the year.

^PRESENTING THE ESSENCE OF INVENTION

The essence of invention is that fluid stream generates the turning moment on curved open blade. where the direction and course of moving the blade and fluid is the same.The effect of curved blade is known and can not be replaced resp. utilization effects are to 80%.

In this invention the blades are in reverse shift protected from action of force producing the turning momenU Different from classic windmills).

The mechanical protection of blades in reverse shift from action of fluid force is at the same time the deflector of fluid stream towards the blades exposed to maximum fluid force. Increase of fluid force concentration is realized by additional movable deflector.This fixed and movable( together with air rotor)deflector allow the increase of effect on the blades. Construction allows self-adjusting resp. IbI lows the change of fluid stream.

Construction of rotor turbine is placed on vertical base(axle) over the support allowing rotation of

360 degrees.lt means that all changes of fluid stream generate the same working effect on the shaft.

S)BRIEF DESCRIPTION OF THE DRAWING attached drawings A. B and C are used in presenting the description and clearly point out the basic elements of construction being the subject of protection.clearly showing mutual functionality and elementary function being the subject of use.

-drawing A shows side projection of air turbine with deflector

-drawing B shows side projection of two air turbine on one support

-drawing C shows side projection of one air turbine on support 6)DETAILED DESCRIPTION OF AT LEAST ONE WAY OF INVENTION REALIZATION One of the ways ol ^"realizing the invention is given under name Vertical air turbine that is registered under different number audit is different by position of main shaft to the ground or in special case it makes an integral part of shaft rotating around and support with stabilizer and deflector.

Functionality of construction is made by mechanical protection of the blacles,in reverse shift,thal at the same time is a deflector of fluid stream to open blades. To increase effect it is anticipated a pair of working turbines to be placed on the same siipport.Different distance of stabilizer and deflector from the shaft allows selfadjusting of these turbines to the line of fluid resp.the smallest resistance to fluid stream. Possibility of horizontal movement(adjusting)is anticipated and turning the stabilizer around its axis to make amortization of thrust force on inclined plane( front deflector)Height of fluid deflector is determined by radius of air turbine and length is equal to the length of rotor of the turbine.lt is important that air deflector covers the lower part of air turbine resp.the blade in reverse shift allowing the action of fluid stream only to open blades in upper part.To increase stability of construction it is anticipated placing of symetrical inclined plane to already existing one and inclined plane with bigger front angle(deflector) than existing deflector.lt means that adjusting is possible on stabilizer and deflector.

Mechanical transfer of rotation of air turbine to generator is not descibed indicating the use of already adopted solutions in practice.

7)THE WAY OF INVENTION APPLICATION

The way of application is determined by the way of application of existing windmills,but this simple construction is imposed as more qualitative solution.Current technological achievements as for the materials that would be used simplify much the construction(in relation to currently existing in use).Additional possibility of use is in substitution of sail. Simplicity of construction resp.of turbine allows mass production. Possible placing near the settlements is the basic advantage resulting in considerable reduction of electric energy loss during its transmission that is more economical in relation to existing solutions. Second advantage including above mentioned is that there are no vibrations produced resp.ultra sound of high frequency harmful for the living creatures. This is one of the more essential disadvantages of existing solutions requiring their placing far from settlements that was limiting the size of construction.
