Title
(EN) VERTICAL-AXIS WIND TURBINE
(FR) ÉOLIENNE À AXE VERTICAL
Abstract
(EN) The vertical-axis wind turbine comprises a shaft (2) rotating around longitudinal axis and multiple hard turbine blades (7) combined into one or more turbine units (1). The one turbine unit (1) is made of one bottom (6) and one top (6) tube rings. The other turbine unit (10) consists of two bottom tube rings (13 and 14) concentrically positioned one above the other and two top tube rings (6 and 1 1) concentrically positioned one above the other. The tube rings (6, 11, 13 and 14) are fixed perpendicularly to the single shaft (2) by means of distribution washers (4) and load-bearing radial ribs (3). In addition to the load-bearing radial ribs (3), the concentric pairs of tube rings (6, 11, 13 and 14) are joined together also with supporting ribs (12). Each turbine blade (7) is attached with its one end to a load-bearing radial rib (3) or to a supporting rib (12) of the top pair of tube rings (6 and 11) and with its other end to the subsequent rib of the bottom pair of tube rings ( 13 and 14).
(FR) L'invention concerne une éolienne à axe vertical qui comprend un arbre (2) tournant autour d'un axe longitudinal et une pluralité d'aubes de turbine rigides (7) combinées en une ou plusieurs unités turbines (1). L'unité turbine (1) est constituée d'un anneau tubulaire inférieur (6) et d'un anneau tubulaire supérieur (6). L'autre unité turbine (10) est constituée de deux anneaux tubulaires inférieurs (13 et 14) positionnés de manière concentrique l'un au-dessus de l'autre et des deux anneaux tubulaires (6 et 11) positionnés de manière concentrique l'un au-dessus de l'autre. Les anneaux tubulaires (6, 11, 13 et 14) sont fixés perpendiculairement à l'arbre (2) par des rondelles de distribution (4) et des nervures radiales porteuses (3). Outre les nervures radiales porteuses (3), les paires concentriques d'anneaux tubulaires (6, 11, 13 et 14) sont également assemblées à l'aide de nervures de support (12). Chaque aube de turbine (7) est fixée par l'une de ses extrémités à une nervure radiale porteuse (3) ou à une nervure de support (12) de la paire supérieure d'anneaux tubulaires (6 et 11) et par son autre extrémité à la nervure suivante de la paire inférieure d'anneaux tubulaires (13 et 14).
