Title (EN) A ROTOR FOR A VERTICAL AXIS WIND TURBINE
(FR) ROTOR POUR ÉOLIENNE À AXE VERTICAL
Abstract:
(EN) There is described a rotor for a vertical axis wind turbine comprising: first and second blades (6a, 6b) connected to one another and arranged to rotate around an axis (10); wherein the first and second blades (6a, 6b) are disposed 180° apart with respect to one another and are offset from the axis (10) in a radial direction; wherein an inner edge (14, 14') of each blade (6a, 6b) is spaced radially inwardly from an outer edge (12, 12') of the opposing blade (6a, 6b) to form a pair of diametrically opposed openings (26a, 26b) which open in opposite directions; wherein each of the first and second blades (6a, 6b) comprises a first curved section (20) and a second oppositely curved section (22), the first and second curved sections (20, 22) being separated by a point of inflection (24); and wherein the first and second curved sections (20, 22) of the first and second blades (6a, 6b) overlap one another to form a passageway (28) between the first and second blades (6a, 6b) which extends between the openings (26a, 26b).
(FR) L'invention concerne un rotor destiné à une éolienne à axe vertical comprenant : des première et seconde pales (6a, 6b) reliées l'une à l'autre et agencées pour tourner autour d'un axe (10) ; les première et seconde pales (6a, 6b) sont disposées à 180° l'une par rapport à l'autre et sont décalées par rapport à l'axe (10) dans une direction radiale ; un bord interne (14, 14') de chaque pale (6a, 6b) est espacé radialement vers l'intérieur par rapport à un bord externe (12, 12') de la pale opposée (6a, 6b) pour former une paire d'ouvertures diamétralement opposées (26a, 26b) qui s'ouvrent dans des directions opposées ; chacune des première et seconde pales (6a, 6b) comprenant une première section incurvée (20) et une seconde section incurvée de façon opposée (22), les première et seconde sections incurvées (20, 22) étant séparées par un point d'inflexion (24) ; et les première et seconde sections incurvées (20, 22) des première et seconde pales (6a, 6b) se chevauchant mutuellement pour former un passage (28) entre les première et seconde pales (6a, 6b) qui s'étend entre les ouvertures (26a, 26b).
