Abstract

The wind-powered device has a vertical axis and in particular a section acting as a deflector for the poles. An even number of supporting arms 2 are mounted on a rotating vertical shaft 1. Streamlined blades 3 at the ends of the arms are formed by a body with a leading edge 6 and pressure and suction faces 4, and a deflector 5. The deflector has the shape of a half circumference with a diameter 8/100 of that of the wind-powered device, and a diameter parallel to the radius of the machine. The device is intended to convert wind power into useful mechanical power with high efficiency.

Description

Description
La présente invention concerne les éoliennes à axe vertical.Description
The present invention relates to vertical axis wind turbines.

Il existe des éoliennes de ce type - machines à aubes pivotantes - machine à clapets battants - machine à cache orientable - machine Darrieus - machine Savonius, etc. There are wind turbines of this type - swivel vane machines - swing valve machine - machine with adjustable cover - Darrieus machine - Savonius machine, etc.

mais ces éoliennes présentent les inconvénients suivants : vitesse en bout de pales variant entre U/V 6,5 et 5 et parfois des mises en route avec moteur auxilliaire et système de régulation électronique chers et complexes. La présente invention mise à supprimer ces inconvénients.but these wind turbines have the following drawbacks: speed at the tip of the blades varying between U / V 6.5 and 5 and sometimes start-ups with expensive and complex auxiliary motor and electronic regulation system. The present invention overcomes these drawbacks.

Elle comporte en effet : un axe vertical (I) pivotant autour d'un point 0. I1 est monté sur paliers fixés eux-même sur un support massif en béton, poteau métallique ou autre. Sur cet axe sont fixés horizontalement et sur un même plan plusieurs supports de pale (2) d'un nombre pair. Ces supports peuvent être des tubes, des bras en treillis ou un plateau, ensemble boulonnés, soudés ou autre liaison mécanique rigide. Le nombre de ces supports donc des pales (3) qui sont un profil aérodynamique est fonction du diamètre de la machine. Généralement, huit et répartis régulièrement autour de l'axe suivant la formule
o o 360 : 8 = 45. Au bout de ces supports sont fixées verticalement ces pales (3) d'une certaine hauteur fonction de la puissance de la machine.It in fact comprises: a vertical axis (I) pivoting around a point 0. I1 is mounted on bearings themselves fixed on a solid concrete support, metal post or other. On this axis are fixed horizontally and on the same plane several blade supports (2) of an even number. These supports can be tubes, lattice arms or a plate, bolted, welded assembly or other rigid mechanical connection. The number of these supports therefore of the blades (3) which are an aerodynamic profile is a function of the diameter of the machine. Generally, eight and distributed regularly around the axis according to the formula
oo 360: 8 = 45. At the end of these supports are vertically fixed these blades (3) of a certain height depending on the power of the machine.

Elles sont fixées perpendiculairement aux supports (2) et leur squelette est une partie de la circonférence décrite par leur centre aérodynamique en rotation. autour de l'axe (I). Ces pales sont constituées de deux pièces dont l'une est le corps (3) comportant un bord d'attaque (6) un intrados, un extrados (4) et un déflecteur (5). Ces pales peuvent être construites en bois, résine, laminés ou tout autre matériaux coulés, thermoformés ou autres. Elles sont donc un profil aérodynamique ayant un squetette défini plus haut et d'une longueur égale à 180/10000 du diamètre de la machine. Le bord d'attaque (6) est défini par une demie circonférence de diamètre égal à 70/10000 du diamètre de la machine.They are fixed perpendicular to the supports (2) and their skeleton is a part of the circumference described by their aerodynamic center in rotation. around the axis (I). These blades are made up of two parts, one of which is the body (3) comprising a leading edge (6), a lower surface, an upper surface (4) and a deflector (5). These blades can be constructed of wood, resin, laminates or any other cast, thermoformed or other materials. They are therefore an aerodynamic profile having a squetette defined above and with a length equal to 180/10000 of the diameter of the machine. The leading edge (6) is defined by a half circumference of diameter equal to 70/10000 of the diameter of the machine.

La ligne droite reliant les deux bouts de cette demie circonférence est parallèle au diamètre de la machine et son centre est un point du squelette. The straight line connecting the two ends of this half circumference is parallel to the diameter of the machine and its center is a point of the skeleton.

Des deux points ci-dessus partent deux lignes intrados extrados reliées au bord de fuite soit l'autre extrémité du squelette. L'une de ces lignes est droite, c'est celle qui est intérieure à la machine. L'autre est o une courbe qui a une flèche égale à 7/1000 du diamètre de la machine et l'arc de cercle décrit est disposé à l'extérieur de la machine.From the two points above, there are two intrados extrados lines connected to the trailing edge or the other end of the skeleton. One of these lines is straight, it is the one inside the machine. The other is o a curve which has an arrow equal to 7/1000 of the diameter of the machine and the arc of a circle described is placed outside the machine.

Le déflecteur (5) est également défini par une demie circonférence o de diamètre égal à 80/1000 du diamètre de la machine et son diamètre est également parallèle au rayon de la machine. Son centre est le point défini par l'intersection du squelette et de la demie circonférence formant le bord d'attaque. Ce déflecteur (5) est fixé solidairement au corps de la pale par tout moyen mécanique connu : boulons, vis, soudure, collage, etc.. Le dispositif suivant l'invention est un moteur éolien destiné à la production d'énergie. The deflector (5) is also defined by a half circumference o with a diameter equal to 80/1000 of the diameter of the machine and its diameter is also parallel to the radius of the machine. Its center is the point defined by the intersection of the skeleton and the half circumference forming the leading edge. This deflector (5) is fixed integrally to the body of the blade by any known mechanical means: bolts, screws, welding, bonding, etc. The device according to the invention is a wind motor intended for the production of energy.
