以PVC製作專業風車的實作探究與科普活動
Professional Wind Turbine for Science Education
摘要
不同於一般科普活動中之風車製作，多年以來，作者一直強調風車運轉的科學原理，提倡專業風車之製作。在本文中，作者修改了難度較大的風車製程，設計一種更為簡易的方法，製成仍然符合專業風車原理的風車，這樣的風車葉片形狀和密實度都符合專業風車的要求，每個區段的傾角都適當安排，在轉動時，攻角都在能充分產生升力的範圍內，仍大致具有專業風車之性能，且仍然能夠用來進行風車之科普教育，凸顯專業風車的原理，雖然在翼形剖面未盡理想，但仍近似理想之翼形剖面。這項變通的做法，突破了專業風車科學教育的瓶頸，一方面可以利用這樣的專業風車，引入風車科技的精彩內容；另一方面，實作活動之費用、人力需求與對場地造成的問題，都被限縮到完全可行的範圍。

In addition to solar power, wind power can be described as the most reliable green energy at present. Wind power technology is already very mature, but it is still developing. Unlike the windmills assembled in other science activities, the author has been emphasizing the scientific principles of windmill operation for many years and advocating the production of professional windmills. In this article, the author modifies the windmill process, which was difficulty and inconvenient and designs a simpler method to make a windmill that still conforms to the principle of significant knowledge about windmills. Such a windmill still has the performance of a professional windmill. It can still be used to carry out windmills science education that highlights the principle of professional windmills. This alternative approach has broken through the bottleneck of the scientific education of professional windmills. On the one hand, it can use such professional windmills to introduce the exciting content of windmill technology. On the other hand, the costs, manpower, and problems caused to the venues of the actual activities are all limited to a completely feasible scope.
