Abstract

Изобретение относится к лопасти (100) ротора для ветряной турбины, включающей в себя комель (102) лопасти ротора, наружную кромку (104) лопасти ротора, переднюю кромку (106) и заднюю кромку (108). Передняя кромка (106) и задняя кромка (108) определяют хорду (110) профиля, длина которой увеличивается от комля (102) лопасти ротора к наружной кромке (104) лопасти ротора. Средние точки (112) хорды профиля определяют проходящую от комля (102) лопасти ротора к наружной кромке (104) лопасти ротора среднюю линию (114) лопасти ротора, и средняя линия (114) лопасти ротора разделяет наружную кромку (104) лопасти ротора на участок (116) передней кромки и участок (118) задней кромки, причем на наружной кромке (104) лопасти ротора расположено концевое крылышко (120), которое проходит только вдоль участка (118) задней кромки.
