Abstract
"LâMINA DE ROTOR PARA UMA INSTALAçãO DE ENERGIA EóLICA". A invenção diz respeito a uma lâmina de rotor para uma instalação de energia eólica. O grau de eficiência de lâminas de rotor é determinado pelo ângulo de afluxo, isto é, o ângulo entre a corda de perfil da lâmina de rotor e a direção de afluxo do ar. Particularmente no caso de instalações de energia eólica, o ângulo de afluxo depende da velocidade de lâmina de rotor - isto é, da velocidade de rotação do rotor - e da direção do vento: a direção de afluxo é distinguida pelo vetor de soma da velocidade do vento V~ Vento~ e da velocidade da ponta de lâmina de rotor V~ Ponta~, a velocidade de afluxo efetiva V~ eff~ ver a figura 1, V~ eff~ = <sym>V~ Vento~^ 2^ + V~ Ponta~^ 2^(2). O objetivo da invenção é, processo conseguinte, aquele de redução da sensibilidade de uma lâmina de rotor a fluxos de vento turbulentos. Este objetivo é alcançado por uma lâmina de rotor para uma instalação de energia eólica, a qual é dividida em sua direção longitudinal em pelo menos duas porções que são integralmente conectadas conjuntamente e que são projetadas para diferentes índices de alta velocidade, em que o índice de alta velocidade, associado com o coeficiente de potência máxima, da porção que está mais afastada da raiz de lâmina de rotor, é maior do que o índice de alta velocidade, associado com o coeficiente de potência máxima, da porção respectivamente disposta mais próxima à raiz de lâmina de rotor.
