Title (EN) VARIABLE CROSS SECTION TYPE BLADE FOR HORIZONTAL AXIS WIND POWER GENERATOR

Abstract: front page image
(EN)The present invention provides a variable cross section type blade for a horizontal axis wind power generator. More particularly, the present invention relates to a variable cross section type blade for a horizontal axis wind power generator, the blade including: a main wing having a diamond type airfoil-shaped cross section vertically symmetrical with respect to a chord line thereof; and an auxiliary wing having a cross section vertically symmetrical to that of an upper surface part of the main wing, the auxiliary wing coupled to the main wing while being vertically rotatable, so that, when the main wing rotates, the auxiliary wing can rotate up and down by its own weight to change the cross sectional shape of the main wing. Therefore, the blade can smoothly rotate even by gentle breeze and thus can significantly improve power generation efficiency. Moreover, the blade can safely withstand even a strong wind, such as occurring in a typhoon, and thus has significantly enhanced durability.
(FR)La présente invention concerne une pale du type à section transversale variable pour un générateur d'énergie éolienne à axe horizontal. Plus particulièrement, la présente invention concerne une pale du type à section transversale variable, pour un générateur d'énergie éolienne à axe horizontal, qui comprend : une aile principale ayant une section transversale en forme de profil aérodynamique du type diamant, verticalement symétrique par rapport à une ligne de corde de celle-ci ; une aile auxiliaire ayant une section transversale verticalement symétrique par rapport à celle d'une partie de surface supérieure de l'aile principale, l'aile auxiliaire étant couplée à l'aile principale tout en pouvant tourner verticalement, de telle sorte que, lorsque l'aile principale tourne, l'aile auxiliaire peut tourner vers le haut et vers le bas sous son propre poids pour changer la forme de section transversale de l'aile principale. Par conséquent, même une brise douce peut faire tourner la pale de façon régulière, améliorant ainsi significativement le rendement de génération d'énergie. De plus, la pale peut supporter sans danger un vent fort, tel que celui se produisant pendant un ouragan, et présente ainsi une durée de vie significativement améliorée.
(KO)본 발명은 수평축 풍력발전기용 가변 단면형 블레이드에 관한 것으로, 보다 상세하게는 시위선(chord line)을 중심으로 상하대칭을 이루는 다이아몬드형 에어포일형태의 단면을 가지는 주날개의 하면부에 주날개의 상면부와 상하대칭을 이루는 단면을 가지는 보조날개를 상하로 회동가능하게 결합하여 주날개의 회전시 보조날개가 자중에 의해 상하로 회동하면서 주날개의 단면형상을 가변시킬 수 있게 구성함으로써, 미풍에도 원활하게 회전할 수 있게 하여 발전효율을 대폭 향상시킬 수 있도록 할 뿐만 아니라 태풍과 같은 강풍에도 안전하게 견딜 수 있게 하여 내구성을 대폭 향상시킬 수 있도록 하는 수평축 풍력발전기용 가변 단면형 블레이드에 관한 것이다.
