Abstract
"TURBINA DE VENTO COM NACELA" A estrutura de lâmina de uma turbina de vento é fornecida e possui resistência suficiente para suportar uma carga grande esporádica e uma durabilidade aumentada. A lâmina pode ser formada em um perfil de lâmina mais fino, com o qual o desempenho da lâmina é aperfeiçoado, a eficiência da turbina de vento aumentada, e o ruído induzido pelo vértice Karman reduzido. A lâmina é feita de metal e formada em uma lâmina de peça única ou uma lâmina tipo dividida consistindo de um corpo principal de lâmina feito de metal e um elemento de extremidade traseira feito de metal diferente do utilizado para o dito corpo principal de lâmina, o elemento de extremidade traseira sendo fixo à extremidade traseira do dito corpo principal de lâmina, o entalhe sendo formado na parte de borda traseira da lâmina ao longo do comprimento da mesma, o entalhe sendo formatado como uma parte serrilhada de dentes triangulares, dentes em forma de trapézio ou dentes em forma de serra, a razão (h/<sym>) da altura do dente h para a espessura 8 da camada limítrofe desenvolvida na superfície da lâmina sendo: h/<sym> = 1.0 ~ 10.0, e a razão (h/p) da altura de dente h para inclinação p é: h/p = 0.5 ~ 5.0.
