Abstract

LÂMINA DE TURBINA DO VENTO E MÉTODO PARA CONTROLAR A ELEVAÇÃO DE TAL LÂMINA. A presente invenção refere-se à lâmina de turbina do vento que compreende uma seção aerodinâmica de formato modificável (1; 2) que se estende tanto no sentido de corda quanto de envergadura e tem um formato padrão não modificado, um conduíte (15; 25; 35, 36; 45) que se estende a partir de dentro da lâmina em direção à parte externa da lâmina, e uma parte externa que compreende um regulador de fluxo que está situado na seção aerodinâmica de formato modificável e bloqueia o conduíte quando a seção aerodinâmica de formato modificável apresenta o seu formato padrão, e não bloqueia o conduíte quando a seção aerodinâmica de formato modificável apresenta um formato modificado. Nessa última situação, o conduíte é aberto para fora da lâmina e um dispositivo para trocar um fluido entre a parte interna e a parte externa da lâmina é assim definido.
