Abstract
Description
Claims (3)
- 수직축 풍력발전기의 회전장치로 이용할 수 있는 풍력회전날개의 형상으로, 한면은 항력계수가 크고 반대면은 항력계수가 작은 (도 1)과 같은 반관형 풍력회전날개
- 청구항 1에 있어서 풍력에 의한 와류 현상과 가속시 순간진공현상을 제거하여 항력을 최소화 하기 위해 만든 (도 3)과 같은 통풍홈
- 청구항 2에 있어서 (도 4a)와같이 회전날개에 흘러들어간 바람이 양방향에서 경사면을 따라 되돌아 나와 서로 부딪치면서 만들어진 공기층이 통풍홈으로 바람이 통과하는 것을 막아 항력을 더욱 증가시키기 위하여 만든 (도 3)과 같은 퉁풍홈 뒷면의 만남각이 60°~ 80°범위인 경사면
