Description

DESCRIZIONE
L’invenzione riguarda una “turbina eolica ad asse verticale” (ovvero una macchina motrice rotante a fluido comprimibile che converte la potenza del vento in potenza elettrica o meccanica, con l’asse di rotazione del rotore disposto verticalmente rispetto al punto dove la macchina viene installata) in cui, fatto innovativo rispetto allo “stato deìl’arte”, il rotore è inserito dentro “convogliatore” che assolve il compito di canalizzare il vento contro il rotore stesso.
Attualmente le turbine eoliche ad asse verticale prevedono che l’elemento rotante sia disposto in “campo aperto”, ovvero che non ci siano strutture tra l’elemento rotante (altrimenti detto rotore o girante) ed il vento che lo eccita.
Tale fattore costituisce una limitazione al rendimento (inteso come rapporto tra la potenza resa e la potenza disponibile) della macchina, in quanto parte della potenza del vento va ad ostacolare la rotazione del rotore.
