Abstract
PÁ DE TURBINA EÓLICA CURVADA, PÁ CURVADA E ROTOR DE TURBINA E ROTOR DE TURBINA EÓLICA. A presente invenção refere-se a uma pá de turbina eólica curvada (20) que inclui um corpo da pá (24) que se estende ao longo de um comprimento entre uma base (26) e uma ponta (28) da pá (20). Um eixo geométrico de arfagem (36) se estende através da base (26) da pá (20). Uma linha de referência (48) define um desvio do eixo geométrico de arfagem (36) e corresponde a um formato curvado da pá (20) ao longo de seu comprimento. A linha de referência (48) tem uma curva zero na base (26), uma inclinação zero na base (26) e uma curvatura positiva (66) ao longo de um segmento em 25% do comprimento da base (26) à ponta (28) da pá (20).
