Abstract

TURBINE A FLUX TRANSVERSE L'invention concerne un système de turbine à flux transverse (10), comprenant un arbre (1), une pluralité de bras (2, 2’, 2’’) montés sur l’arbre, ,une pluralité de pales (6, 6’, 6’’), chaque pale étant montée sur un bras respectif, et étant libre en rotation, et pour chaque pale, un dispositif de butée (21 , 21’, 21’’), définissant une première position de butée et une deuxième position de butée limitant les mouvements de rotation de ladite pale entre lesdites première et deuxième positions de butée, de sorte que la pale correspondante soit libre en rotation sur une plage angulaire (P) d’au moins 70°, cette valeur étant incluse, et d’au plus 100°, cette valeur étant exclue, dans lequel l’angle (I) entre la première position de butée et la direction tangentielle (T, T’, T’’) est entre 35° et 55°, en valeur absolue, et l’angle (E) entre la deuxième position de butée et la direction tangentielle est entre 35° et 55° en valeur absolue Figure pour l’abrégé : figure 1The invention relates to a cross-flow turbine system (10), comprising a shaft (1), a plurality of arms (2, 2', 2'') mounted on the shaft, a plurality of blades (6, 6', 6''), each blade being mounted on a respective arm, and being free to rotate, and for each blade, a stop device (21, 21', 21''), defining a first stop position and a second stop position limiting the rotational movements of said blade between said first and second stop positions, so that the corresponding blade is free to rotate over an angular range (P) of at least 70°, this value being included, and of at most 100°, this value being excluded, in which the angle (I) between the first stop position and the tangential direction (T, T', T'') is between 35° and 55°, in absolute value, and the angle (E) between the second stop position and the tangential direction is between 35° and 55° in absolute value Figure for abstract: Figure 1
