Abstract

The machine has a rotor (1), crown (2) and a fixation arm. The rotor has an axle oriented at 45 degrees with respect to the vertical. The crown has hollowed parts permitting to push the wind on the rotor on a section and an upper disk of the crown, respectively, and another hollowed part on a lower disk of the crown. A screen pierced by openings on the lower disk reorients the wind in the rotational direction of the rotor on the upper disk of the crown. An adjustable fantail (11) orienting the crown is mounted on the axle.

Description

-1 --1 -

La présente invention technique concerne une machine aérodynamique à axe à 45 mue par les flux conjugués du vent relatif direct additionné aux turbulences actives créant l'effet multiplicateur recherché pour le production électrique par la configuration technique angulaire des aubes fixes et mobiles et de l'orientation à 45 de l'axe de la machine.  The present technical invention relates to an aerodynamic machine with axis 45 driven by conjugate fluxes of the direct relative wind added to the active turbulence creating the desired multiplier effect for electrical production by the angular technical configuration of the fixed and mobile vanes and the orientation at 45 from the axis of the machine.

De par sa configuration technique, l'aérogénérateur à axe vertical présente une partie très limitée de la surface de la tranche motrice du rotor à l'action du vent sans considération appropriée des pertes conjuguées dues aux turbulences actives et réactives qui sont la cause d'une grande perte de rendement de la machine qui se trouve limitée à une production aléatoire d'une énergie électrique de très faible puissance.  Due to its technical configuration, the vertical-axis aerogenerator has a very limited part of the surface of the rotor drive section to the action of the wind without appropriate consideration of the combined losses due to active and reactive turbulence which are the cause of a great loss of efficiency of the machine which is limited to a random production of electrical energy of very low power.

Les dispositifs techniques constituant l'invention permettent un rendement actif à bas régime et par vent faible sur 60% de la surface soumise à l'action éolienne, en rendant actives simultanément les parties tranche et disque du rotor par une inclinaison de l'axe de rotation et par un système d'ouies ajourées.  The technical devices constituting the invention allow an active efficiency at low speed and low wind on 60% of the surface subjected to the wind action, while simultaneously making active the rotor blade and disk portions by an inclination of the axis of the rotor. rotation and by a system of perforated openings.

Le dispositif selon l'invention est d'incliner l'axe vertical du rotor mobile selon un angle précis de 45 par rapport à l'horizontal.  The device according to the invention is to incline the vertical axis of the movable rotor at a precise angle of 45 relative to the horizontal.

La conséquence est l'orientation au vent non seulement de la tranche active du rotor mais également de celle de son disque. La surface dynamique activée par le vent est ainsi quasiment multipliée par deux.  The consequence is the wind direction not only of the active slice of the rotor but also that of its disk. The dynamic surface activated by the wind is thus almost doubled.

Le dispositif selon l'invention est techniquement complété par une couronne mobile indépendante du rotor de la machine, orientée par le vent relatif agissant sur un gouvernail: cette couronne comporte des parties évidées, des écrans rigides et des ouies ajourées; elle dirige la puissance éolienne sur les aubes actives par les parties évidées, empêche l'action du vent relatif par les écrans pleins, réoriente la puissance éolienne motrice dans le sens de rotation du rotor par les ouies ajourées.  The device according to the invention is technically completed by a movable ring independent of the rotor of the machine, oriented by the relative wind acting on a rudder: this ring comprises recessed portions, rigid screens and openwork apertures; it directs the wind power on the active blades by the recessed parts, prevents the action of the relative wind by the solid screens, redirects the power wind power in the direction of rotation of the rotor by the perforated openings.

Le moyeu évidé du rotor enferme les dispositifs de la production de l'énergie électrique. Le nombre d'aubes mobiles (de 6 au minimum) est multiplié à l'image d'une turbine en fonction du diamètre général de la machine, le diamètre variant à la fabrication selon la production électrique à fournir. La forme des aubes mobiles selon l'invention est inscrite dans un triangle isocèle rectangle, les deux extrémités, côté disque, tangeantant les deux côtés du triangle formant l'angle droit; l'extrémité, côté tranche, foiniant une aube secondaire pour améliorer et guider la puissance éolienne par la tranche du rotor: celui-ci fonctionne ainsi de quelque orientation que vienne le vent.  The hollow hub of the rotor encloses the devices of the production of the electrical energy. The number of blades (at least 6) is multiplied in the image of a turbine according to the overall diameter of the machine, the diameter varies in the manufacture according to the electricity production to be provided. The shape of the blades according to the invention is inscribed in a right isosceles triangle, the two ends, disk side, tangenting the two sides of the triangle forming the right angle; the end, slice side, foiniant a secondary blade to improve and guide the wind power by the edge of the rotor: this one thus works of some direction that comes the wind.

L'ensemble du dispositif constituant l'invention est fixé par une potence réglable sur un bâtiment; il peut aussi être fixé sur un mat, un socle, également posé et fixé sur la pente d'un toit.  The entire device constituting the invention is fixed by an adjustable bracket on a building; it can also be fixed on a mat, a base, also placed and fixed on the slope of a roof.
