Abstract

본 발명은 풍력발전기의 날개에 관한 것으로, 더욱 상세하게는 고리가 형성된 수평축 풍력발전기의 날개에 관한 것이다. 날개에 고리를 형성하여 고리가 모든 날개를 하나로 동결함으로 인하여, 날개의 두께를 얇게 할 수 있어서 날개의 무게가 가볍게 되고, 날개의 폭을 넓게 할 수 있고, 날개의 수를 다수로 할 수 있어서 날개의 효율을 극대화시키고, 날개가 고리에 고정되어 있으므로 태풍 등의 강풍에 부러짐 현상을 방지할 수 있고, 바람이 약한 곳에서도 발전이 용이한 고리 있는 수평축 풍력발전기의 날개에 관한 것으로서, 분할제작 방법으로는 고리를 날개의 수로 나뉘어, 날개 한 개와 나뉜 고리 한 개를 묶어서 용접이나 나사 등으로 동결하거나, 날개 한 개와 나뉜 고리 한 개 묶음을 주조법으로 일체로 형성한다. 마그네슘 합금, 텅스텐 합금 등을 이용하면 가볍고 견고해서 항구적으로 이용 가능한 고리 있는 수평축 풍력발전기 날개에 관한 것이다.
