Abstract

LáMINA DE ROTOR PARA UMA INSTALAçãO DE ENERGIA EóLICA A invenção refere-se a uma lâmina de rotor para um instalação de energia eólica e a uma instalação de energia eólica compreendendo um rotor com lâminas de rotor deste tipo. O objetivo da invenção é evitar as desvantagens acima mencionadas e prover um melhor desempenho total. Para conseguir isto, a invenção prevê uma lâmina de rotor com uma relação de arraste, em particular na região central ou de painel principal do dito rotor cujo valor excede 80%, preferivelmente 90% do valor máximo da dita relação na faixa de <sym>2<198> a partir do de passo ótimo do dito rotor.
