Abstract

"LâMINA DE ROTOR PARA INSTALAçãO DE ENERGIA EóLICA, E, INSTALAçãO DE ENERGIA EóLICA" Diferentes formas de lâminas de rotor para instalações de energia eólica são conhecidas. Em uma instalação de energia eólica, os rotores e mais particularmente suas lâminas são a principal fonte de ruído. Para melhorar aceitação de energia eólica e cumprir com a legislação de redução de ruído, o objetivo é trabalhar na direção de manter emissões de ruído tão baixa quanto possível, especialmente desde que as instalações de energia eólica são freq³entemente estabelecidas em áreas residenciais próximas. O presente ruído emitido por instalações de energia eólica ou sistemas de conversão de energia eólica também significa que elas encontram resistência de setores da população. Como resultado, tais instalações são algumas vezes difíceis ou até impossíveis para instalar desde que, devido aos padrões de proteção de meio ambiente aplicável e o fato de que o ruído também é considerado uma forma de poluição do meio ambiente, as autoridades recusam permissão para instalações de energia eólica. O objetivo da invenção é portanto para adicionalmente reduzir as emissões de ruído de instalações de energia eólica. Para este fim, a invenção proporciona para uma lâmina de rotor ter meios para reduzir um ruído emitido por tal lâmina, o dito meio sendo formado por uma camada que repele líquido e/ou superfície que é configurada em pelo menos uma superfície parcial da lâmina de rotor.
