        The problem, which is settling: the problem of engineering, which lie in the creation of the highly effective autonomous WEP with low speeds of air flows. It is especially urgent for the farms, where the problem of providing their own energy needs is quite vital.

3. THE AIM AND MAIN TASKS OF THE PROJECT

        The aim of the project – laying of the scientific and applied bases of creation of autonomous WEP of low power oriented on the work with mild or weak winds, the effectiveness of usage of which is considerably higher in comparison with existent analogies.
        Practical tasks, on the solving of which the project is aimed:
 1.       To study the existed WEP constructions of low power, its windwheels, blades aiming at defining the best of them according to the criteria :
 –       price of one kW of WEP power, which is setting;
 –       average annual capacity kW/h of produced energy on the one kW of power set by WEP;
 –       minimal speed of AF, with which WEP starts working;
 –       speed of AF, with which WEP reaches to nominal power;
 –       maximum permissible speed of AF for the safe WEP exploitation.
 2. To explain thoroughly the benefits of the proposed autonomous WEP of low power according to the criterion of effectiveness of using in conditions of mild or weak winds.
 3. To develop methodologies of calculation of the blade’s optimal profile, optimal windwheel saturation by blades and optimal speed of its rotation, optimal correlation of the parameters of the master nodes of WEP.
 
4. MODERN STATE OF THE PROBLEM
       Groundwork of domestic and foreign scientists on the mentioned problem
        Dominant contribution in the development of designing and projecting of WEP have been made by E.R. Fateev, Ya.I. Shefter, V.N. Andrionov, E.R. Abramovskyj, M.A.Malyshev, O.G. Denysenko and others. Bases of the theory of aerodynamical calculation of air engines were laid by G.Kh. Sabinym and published in the works CASI already in the 1930-th of the last century. After that results of the researches of aerodynamics of the blade of high-speed windwheel (HW) were published in the thematic collection of articles “Industrial aerodynamics”. In the recent years mathematical models of wind energy and work of blade in such winds got its development of probability.
        For some years in the last century several thousands of patents and author’s certifications on the invention of new constructions of blades, windwheels, auxiliary equipment on the orientation of the windwheels “on the wind” and the protection of the blades from the excessive and gusty wind were received by the scientists of the developed European countries and USA.
       Much attention was paid to the collection and working out of the information on the character of AF, which exist on the territory of Ukraine. These data were published in the scientific – applied reference book on the climate of USSR in 3rd Series , “ Many years data”. The detailed analysis of the energy resources of the climate of Ukraine was held (M.M. Volevokha, M.I.Gojsa), operational characteristics of effectiveness of using of wind electric aggregates of Ukraine were received (P.F. Vasko, S.A.Bryl) The question of work of WEP was studied in detail in conditions of climate of Crimea.
       In the development of the theory of WEP with HW, their construction at different times were involved scientific associations of Dnipropetrovsk State University, Kyiv Polytechnic University, SPO “Pivdenne”, where within the fulfillment of the conversional program WEP “ Southern – 1250” was created.
     Among foreign scientists, who have made a significant contribution in the solution of the scientific and theoretical problems, connected with WEP, it is necessary to mention T. Omory, D d’Renzo, J.Twidle, A. Wayer, L. Yarosa , G. Obermayer and so on.
        At the same time it’s worth mentioning that the main attention of the scientists in the area of mechanics and electricity, constructors and inventors, was paid to the increasing of effectiveness of work of WEP with HW. The question of highly effective autonomous WEP of low power with low – going windwheel (LW) remains insufficiently explored.
        The results of the previous researches and developments, which are laid in the basis of the project.
        On the MAE department of Lviv National Polytechnic University a complex of scientific – research works with experimental confirmation of the effectiveness of work of WEP, which have LW with blades of modeled profile were held. For this, two experimental patterns of WEP with different devices, that consume mechanical energy were exploited. They were made in the SRL – 40 of Lviv National Polytechnic University. As the result of the laboratory researches of these patterns in the aerodynamic tunnel of Lviv National Polytechnic University their effectiveness and possibility of creation of full-scale pattern were verified by experiment for the further researches.

 5. METHODS, APPROACHES, IDEAS, WORKING HYPOSESIS, WHICH ARE PROPOSED FOR THE SOLUTION OF THE TASKS OF THE PROJECT
        The idea of the project is for the first time to elaborate WEP with LW with much higher indexes of effectiveness in comparison with the existent. Using of WEP with LW is reasonable as they are much cheaper in comparison with high-speed, they are simpler in the exploitation and maintenance.
        Received scientific groundwork on the basis of the proposed theory of motion of laminar AF give confidence in the positive realization of this project. Thus, a new approach to the modeling of the optimal profile of blade of LW is worked out, which give opportunity to provide much higher indexes of effectiveness of work in comparison with the existent LW constructions. On the basis of this the possibility of using of the theory of motion of laminar AF is scientifically justified as the basic for the creation of the broad class of WEP with LW.

6. EXPECTED SCIENTIFIC RESULTS OF THE FULFILMENT OF THE PROJECT
 After the finishing of the fulfillment of the project, the following scientific results are expected :
 -       scientific basis of the engineering methodologies of calculation of the master nodes of highly effective WEP of low power , in particular results of solution of task on optimization of the profile of the blade and the speed of rotation of the windwheel according to criterion of maximum selection of power with AF;
 -       the results of mathematical - computer and laboratory – full-scale experiments with WEP of low power, which has low-going windwheels with blades of the optimal profile.
 -       the effectiveness and benefits of WEP will be confirmed on the experimental constructions, created on the basis of the proposed selection of the parameters of the blade, in comparison with the best world’s models.

7. USAGE OF THE RESULTS :

         The problem of energy supply is getting more and more urgent all around the world. It is interwoven with the questions of ecology and economical usage of available resources. Among the alternative energy sources on the special position is the energy of the air masses, which is widely used in the world practice.
        The specificity of the AF of Ukraine is their relatively low power density, that do not allow to use widely the experience of world’s practice of WEP building. This is why the development of cheap WEP of low single power is actual, and it works with the weak average annual winds. It can be important for the small industrial productions with low energy consuming technological processes, to be the alternative for the power lines for the development of the green tourism, hotel business in the mountains and outside the cities.
         MAE department carry out among the other disciplines theoretical mechanics, mechanics of fluids in which the results of the scientific researches of work of WEP are approved. That’s why this scientific course can give the themes for the Master’s and Candidate’s papers. Thus, each year, on the proposed thematics of the project several Master’s qualification projects are done, carrying out of the one candidate’s thesis and one chapter of doctoral thesis is planned. As the results of the performed researches publishing of the educational aid and a chain of patents on the method of creation of the highly effective autonomous WEP of low power, oriented on the work with AF of low-speed are planned.
        Domestic organizations, that confirm the interest in the results of work on the project thematics:
 LLP “Leghen”, SPF “NOTEKA”, SPO ”Vitroen” together with SPO “Pivdenne”, PE SPF “Mekhatronika”.
