Abstract

La présente invention se rapporte au génie énergétique et notamment à la conception d'installations éoliennes de production d'énergie. Elle peut s'utiliser pour produire de l'énergie électrique grâce à la transformation du flux aérien éjecté par des installations de ventilation depuis différents locaux (métro, ateliers d'usine, etc.) ainsi que dans des centrales électriques éoliennes. La centrale électrique éolienne comprend un rotor réalisé sous la forme d'un disque sur lequel sont montées des pales se présentant comme des ailes aérodynamiques, qui sont montées de façon qu'un intervalle les sépare de l'arbre du rotor qui est relié à l'arbre du générateur électrique; un carénage, monté sur l'arbre en amont du rotor en suivant le flux aérien, entoure l'intervalle entre les bords internes des pales et un concentrateur disposé en amont du rotor en suivant le flux aérien. Les extrémités des pales sont biseautées par rapport à l'axe de l'arbre. Le concentrateur est monté sur les parties périphériques des extrémités des pales de manière à former un intervalle avec le carénage. Par conséquent, il est possible d'augmenter le taux d'utilisation de l'énergie du flux aérien et de simplifier sensiblement la structure de la centrale électrique éolienne ainsi que sont exploitation.
