Abstract

turbina de eixo horizontal para um gerador eólico, e, gerador eólico. turbina de eixo horizontal para um gerador eólico, a turbina compreendendo um cubo e duas pás opostas, a turbina sendo distinguida pelo fato de que: o dito cubo é adaptado para ser conectado direta ou indiretamente a uma barra de suporte (p) do gerador eólico e compreende uma peça rotativa (m2), à qual as ditas duas pás são conectadas; as ditas duas pás são alongadas em uma direção longitudinal operacionalmente ortogonal ao eixo central de rotação (a) da turbina, cada uma das ditas duas pás compreende uma aba (a1, a2) e um defletor (d1, d2) fixamente conectados à dita peça rotativa (m2), a aba e o defletor tendo uma cabeça e uma cauda, a cauda do defletor sendo proximal à cabeça da aba, o defletor é posicionado à frente da respectiva aba em relação à direção de rotação da turbina, de modo a desviar o fluxo de ar em direção à aba, a cauda de cada defletor é afastada da cabeça da respectiva aba, de modo a definir uma lacuna (l1, l2) entre o defletor e a aba, a aba e o defletor de cada uma das ditas duas pás são conectados em suas extremidades mais externas por um elemento de conexão (f).
