Abstract

a invenção refere-se a uma pá de rotor de turbina eólica (1) apresentando um lado superior (13) , um lado inferior (14), uma borda de ataque (16), uma borda de fuga (15), um meio de fixação de cubo (17) e uma ponta de pá (12), sendo que a pá de rotor de turbina eólica (1) está dividida em uma região de cubo (111), uma região central (112) e uma região de ponta de pá (113), estando uma região de raiz (11) do meio de fixação de cubo (17) para a profundidade máxima de pá (smax), sendo que, dentro da pá de rotor de turbina eólica (1), está previsto um canal condutor de ar (23) estendido radialmente para fora para condução de ar sugado da região de sucção (21) para uma região de expulsão (22) disposta na região de ponta de pá (113), e ocorre uma sucção de camada limite, sendo que a sucção do ar ocorre no lado superior (13) da pá de rotor de turbina eólica (1), e está prevista uma cerca de camada limite (28) na região de cubo (111) próxima ao meio de fixação de cubo (17) para impedir um fluxo na direção do meio de fixação de cubo (17).
