Propeller for collecting wind/hydraulic energy, has two blades, each with deflector directed opposite to rotation direction so that one blade increases its wind opposition surface and other blade reduces surface, at one half propeller turn

The propeller has a hub (1) supporting a movable shaft (2) with two blades (3, 4) and a double stop fixed at its center. Each blade has a deflector directed opposite to a rotation direction (8) such that when the wind strikes the propeller, one blade increases its wind opposition surface and the oth...

Abstract The propeller has a hub (1) supporting a movable shaft (2) with two blades (3, 4) and a double stop fixed at its center. Each blade has a deflector directed opposite to a rotation direction (8) such that when the wind strikes the propeller, one blade increases its wind opposition surface and the other blade reduces the surface at one half turn of the propeller, then they reverse the oscillation direction at the other half turn. Hélice à axe vertical et à deux pales oscillantes pour capter l'énergie éolienne ou hydraulique.L'invention concerne une hélice à axe vertical sans gouvernail permettant de capter l'énergie éolienne ou hydraulique, sans avoir à se positionner pour démarrer et tourner dans un sens unique de rotation.Elle est constituée d'un moyeu (1) démontable supportant horizontalement un arbre (2) mobile muni de deux pales (3) (4) identiques comportant un déflecteur (6) (7) dirigé à l'opposé du sens (8) unique de rotation. Une double butée (9) est fixée transversalement sur le centre dudit arbre (2) mobile pour délimiter l'amplitude des oscillations des pales (3) (4).L'hélice selon l'invention est particulièrement destinée à capter l'énergie éolienne ou hydraulique.
