Abstract

L'invention se rapporte à la structure de dispositifs servant à convertir l'énergie cinétique d'un flux libre en va-et-vient d'un milieu continu (gaz, liquide, etc.) en une énergie de rotation d'un rotor mécanique à l'échelle industrielle. La surface interne du stator possède une forme d'hyperboloïde rotative en une seule bande et de type grille formée par des éléments rectilignes (8) sur la surface externe desquels sont montées les pales de guidage (4) du stator (3) et des plaques d'un tube convergent (5). Le rotor (1) comprend des guides qui forment sa surface conique, et des pales rectilignes (2) disposées le long des guides. Les pales servent à la mise en rotation du rotor et à la rotation, ainsi qu'au tourbillonnement du flux passant par la surface latérale de la turbine dans la direction de l'axe de rotation du rotor (1) du côté de la base protubérante de la surface conique du rotor (1). Les éléments rectilignes du stator (3) et les génératrices du rotor en projection sur un plan frontal comportent des points d'intersection, et au moins une des surfaces d'extrémité du rotor (11) et du stator (12) est protubérante afin d'assurer l'écoulement libre du milieu continu.
