Title (EN) ROOT AIRFOIL OF WIND TURBINE BLADE
(FR) PROFIL DE PIED DE PALE D'UNE PALE DE TURBINE ÉOLIENNE
(KO) 풍력발전기 블레이드의 루트 에어포일
Abstract: front page image
(EN)Disclosed is a root airfoil of a wind turbine blade. The root airfoil of a wind turbine blade according to one embodiment of the present invention has a suction surface and a pressure surface formed at the upper side and at the lower side of a chord which interconnects the leading edge and the trailing edge. The operating Reynolds number is 30,000 to 1,000,000, and the angle of attack of the airfoil is 0 to 21 degrees. The maximum lift coefficient is 0.8 to 1.1, and the minimum drag coefficient is 0.02 to 0.07.
(FR)L'invention porte sur un profil de pied de pale d'une pale de turbine éolienne. Le profil de pied de pale d'une pale de turbine éolienne selon un mode de réalisation de la présente invention comporte une surface d'aspiration et une surface de pression formées sur le côté supérieur et le côté inférieur d'une corde qui joint le bord d'attaque au bord de fuite. Le nombre de Reynolds de fonctionnement est de 30 000 à 1 000 000 et l'angle d'attaque du profil est de 0 à 21 degrés. Le coefficient de portance maximal est de 0,8 à 1,1 et le coefficient de trainée minimal est de 0,02 à 0,07.
(KO)풍력발전기 블레이드의 루트 에어포일이 개시된다. 본 발명의 일 실시예에 따른 풍력발전기 블레이드의 루트 에어포일은 앞전(Leading Edge)과 뒷전(Trailing Edge)을 잇는 시위선(Chord)을 기준으로 상측에 형성된 흡입면과 하측에 형성된 압력면을 가지며, 작동 레이놀즈수는 30,000 ~ 1,000,000이고, 에어 포일 받음각은 0°~ 21°이며, 최대양력계수는 0.8 ~ 1.1이고, 최소 항력계수는 0.02 ~ 0.07인 것을 특징으로 한다.
