Abstract

a presente revelação é direcionada a um conjunto de pá de rotor (100) para uma turbina eólica (10). o conjunto de pá de rotor (100) inclui uma pá de rotor (22) que tem superfícies externas que definem lados de pressão e sucção (23, 24), e bordas de ataque e de fuga (26, 28) que se estendem em uma direção geralmente no sentido da envergadura entre uma região interna (36) e uma região externa (38). a região interna (36) inclui uma raiz de pá (34) que tem uma borda de fuga redonda (28). adicionalmente, o conjunto de pá de rotor (100) inclui adicionalmente pelo menos um elemento de separação de fluxo de ar (102) montado em um ou outro ou nos lados tanto de pressão quanto de sucção (23, 24) da pá de rotor (22) dentro da região interna (36) e adjacente à borda de fuga redonda (28). além disso, o pelo menos um elemento de separação de fluxo de ar (102) corresponde a um contorno dos lados de pressão ou sucção (23, 24) da pá de rotor (22). desse modo, o pelo menos um elemento de separação de fluxo de ar (102) é configurado para fornecer uma localização de separação de fluxo de ar fixa na região interna (36) durante a operação padrão.
