Abstract
"LâMINA DE ROTOR, E, INSTALAçãO DE ENERGIA EóLICA". A invenção diz respeito a uma lâmina de rotor e a uma instalação de energia eólica que tem uma lâmina de rotor dotada de uma borda posterior de lâmina de rotor, em que a lâmina de rotor se afila no sentido da borda posterior da lâmina de rotor. A invenção se distingue pelo fato de que, na região da borda posterior da lâmina de rotor, o grau de conicidade da lâmina de rotor aumenta no sentido da borda posterior da lâmina de rotor, e não há escalonamento de tipo degrau na lâmina de rotor, pelo menos na região da lâmina de rotor.
