چکیده

نظر به پتانسیل مناسب انرژی بادی در ایران، امکان بهره‌گیری از توربین‌های بادی کوچک همانند توربین‌های بزرگ برای تأمین بخشی از برق موردنیاز کشور وجود دارد. تحقیق حاضر به مواد مورد استفاده در تولید پره توربین بادی محور افقی کوچک و روش‌های ساخت آن می‌پردازد. به ­این­ منظور چوب و کامپوزیت، به‌عنوان دو ماده اصلی مورد استفاده در ساخت پره، بررسی شده ­اند. در ادامه، روش‌های اصلی تولید پره‌های چوبی شامل ماشین‌های براده­ بردار رایانه‌ای، کنترل عددی و کپی‌تراش و همچنین روش‌های تولید پره‌های کامپوزیتی ازجمله لایه­ چینی خیس، پیش‌آغشته، تزریق رزین و قالب‌گیری تحت فشار مطالعه شده‌اند. سپس روش چاپ سه‌بعدی و مواد پلیمری مورد استفاده در آن به‌منظور تولید پره معرفی شده است. بررسی انجام‌گرفته نشان می‌دهد که پارامتر خستگی، نقش مهمی در تعیین جنس پره دارد و انتخاب روش ساخت با توجه‌به نوع کاربرد و تعداد پره موردنظر، نیازمند تحلیل اقتصادی مرتبط است. باوجود مزایای زیست‌محیطی چوب، پیچیدگی‌ها و هزینه ساخت پره چوبی مانع از تولید سریع و ارزان آن است؛ اما استفاده از کامپوزیت، هرچندکه همراه با معضلات زیست‌محیطی است، برای تولید انبوه پره، اقتصادی‌تر است. روش چاپ سه‌بعدی علیرغم ضعف‌ خستگی، روشی سریع و نسبتاً ارزان برای تولید مدل توربین بادی کوچک برای انجام آزمایش‌های تونل باد است.

چکیده [English]

Regarding the suitable potential for wind energy in Iran, it is possible to employ small wind turbines such as large ones to supply part of the electricity load of the country. The present study deals with materials used in small horizontal axis wind turbine blades and their fabrication methods. To this end, the wood and the composite, as the two main materials used in blades, have been investigated. Then, the main methods of producing wooden and composite blades have been analyzed. Finally, the 3D printing method and polymer materials used in this technique have been introduced. The study shows that the fatigue parameter has an important role in determining the blade’s material and the fabrication method. Despite the environmental benefits of using wood, the complexity and the manufacturing costs prevent rapid and affordable production of wooden blades. On the other hand, the mass production of composite blades is more economical, although it has environmental impacts. Despite the fatigue issue of the 3D printed blades, the 3D printing method is a fast and relatively inexpensive technique for fabrication of small wind turbine models for wind tunnel tests.
