  1. SMALL VERTICAL WIND TURBINES Erol İnelmen ÖZET CONCLUSIONS BACKGROUND Bu çalışmada ana enerji üretim sistemine alternatif olarak “ufak ölçekli dikey rüzgar türbini önermekteyiz İlgili kurumlar tarafından destek aldığı takdirde, önerimizin enerji sorunsalına faydalı olacaktır. There has been in the last century many new and innovative wind power designs aiming at harnessing the freely available energy in the planet. Rotors like Savonius, Storan, Darrieushave been tested and developed. We propose here a simpler version of the double bladed vertical wind turbine to be use in farms which are far from the interconnected power grid (Figure 2.). Design principles have been simplified to help the manufacturing and operation. We argue that these rotors can be well installed in many different location very favourably without the drawbacks that large systems have. We owe the coming generations an economical development scheme that is sustainable. In the years between 1962-1965 the author was involved in the research and implementation of small scale vertical wind turbines as a requirement for his master thesis with the supervision of Prof.Adnan Taşpınar [1]. The work consisted in finding optimal blade profiles and design of turbine rotors having different height to width ratios. This initial work was followed by other work showing the growing importance giving to the subject. In more recent times the author presented his work in an international conference at a time when “cleaner energy” requirements were being considered by goverments all around the world [2]. In the above mentoned conference the idea was to use parametric design approach to facilitate the overall launching of a project: ABSTRACT In this work we propose the use of “small scale vertical wind turbines” as an alternative approach to the mainstream power generation practice. We believe that if a proper start is giving by related agency this proposal will have a positive effect on energy consumption. INTRODUCTION Developed countries such as Denmark, Germany and Spain are aiming to increase the use renewable energy to comply with the requirements they have set for a cleaner environment. For this purpose they are promoting the installation of very efficient “wind power farms” in the regions having most favourable conditions (Figure.1). Unfortunately there have been important complaints about these installations: undesirable sound levels, danger to the life of birds, restrictions to the use of valuable land, etc. . http://www.aero-dyne.net Figure 2. Airfoil Design Model PROPOSAL ACKNOWLEDGEMENT • The interest the various goverments and agencies are giving to mitigate the undesired effects of energy production, is growing. • We propose here the revival of the idea that smaller wind power turbines can be an appropiate alternative to mainstream power generation stations at locations -where demand is small- far from the main populated areas. • The ease of manufacture, erection and operation of vertical turbines is an important factor in favour of this alternative solution. • As a matter of fact vertical turbines do not need to “position” itself with changes in wind directions and can be easily transported to locations as the conditions require. We owe the support of Prof.Özer Arnas in encouraging the author to continue on working on an old project.
