Abstract

L'invention concerne une lame pour un générateur d'énergie d'ouverture/fermeture de type traînée ayant une fonction permettant non seulement l'ouverture/la fermeture de l'espace à l'intérieur de cadres de lame mais également l'ouverture/la fermeture de l'espace entre les cadres de lames en parallèle avec l'axe d'un arbre rotatif qui est formé par couplage des cadres de lames et fournit ainsi une différence de hauteur ayant un coefficient de traînée élevé. Dans ce but, l'invention porte sur un arbre rotatif (2) qui est pourvu de huit cadres de lame (4) espacés à des intervalles de 45 degrés et les cadres de lames adjacents (4) sont couplés par l'intermédiaire de cadres de couplage de cadres de lames (6). Les cadres de lames (4) sont pourvus de rails (5) et les rails (5) sont pourvus d'écrans d'ouverture/fermeture (1). En outre, les cadres de couplage de cadres de lames (6) sont pourvus de rails de cadre inter-lames (8) et les rails de cadre inter-lames (8) sont pourvus d'écrans d'ouverture/fermeture de cadre inter-lames (7). De plus, des écrans (3) sont posés entre les cadres de lames (4) dans une direction orthogonale à l'arbre rotatif (2). Les écrans d'ouverture/fermeture (1) et les écrans d'ouverture/fermeture de cadre inter-lames (7) sont caractérisés en ce qu'ils peuvent être librement ouverts/fermés par une puissance motrice.
