Abstract

The horizontal wind generator is mounted on a vertical column so it is free to rotate in a horizontal plane. A guide vane is fixed to the rear of the tapered conical exhaust duct and orients the inlet duct to the wind. The rotor of the integral alternator is a thin hollow cylinder with radial vanes as spokes, so that the wind passes through the centre of the rotor driving the vane to give rotation. The stator of the alternator lies inside a cylindrical section of the casing between inlet and outlet cones. The alternator is thus constructed of thin materials of large surface area. An eddy current brake unit is mounted behind the alternator rotor to control rotor speed under high winds.

Description

La présente invention concerne un aéro.-générateur dontla propulsion est assurée par une roue à ailettes, et la production de courant assurée par un alternateur à induits périphériques.The present invention relates to an air generator whose propulsion is provided by a impeller, and the production of current provided by an alternator with peripheral armatures.

L'appareil étant en position horizontale.The device being in a horizontal position.

Dans les aérogénérateurs à hélices on constate une fragilité de celles-ci ainsi qu'une limite à leur vitesse de rotation, surtout pour les gros appareils d'où un rendement limité.In propeller-driven wind turbines, there is a fragility of these as well as a limit to their speed of rotation, especially for large devices where a limited yield.

La construction des hélices est) d'autre part onéreuse.The construction of the propellers is) on the other hand expensive.

L'aéro-générateur inventé supprime ce défaut en offrant un appareil compact, slsceptible de vitesses de rotation élevées.The invented air generator eliminates this defect by offering a compact device, capable of high rotational speeds.

Deux variantes sont proposées.Two variants are proposed.

Pour les appareils de forte puissance, l'alterr,ateur est composé d'un stator cylindrique (I) à l'intérieur duquel tourne un rotor dont les induits (2), de faible épaisseur mais de grande surface, dont fixées à sa périphérie libérant son volume inlérieur.  For high power devices, the alternator is made up of a cylindrical stator (I) inside which rotates a rotor whose armature (2), thin but with a large surface area, of which fixed at its periphery releasing its interior volume.

La roue à ailettes (3) multiples est fixée à unt des basons du rot
Four améliorer le rendement une deuxième roue à ailettes peut être fixée sur la deuxième base du rotor.The multiple paddle wheel (3) is attached to one of the rotors
To improve the efficiency, a second impeller can be fixed on the second base of the rotor.

Un capotas enferrne 1 'alternateur. A hood encloses the alternator.

Sa forme est cylindrique en sa partie centrale (il) emiSoitant parflitenent l'a1- ternateur ; évasé en tronc de cône à l'avant et à l'arrière. (5 et 6)
Un empennage (8) arrière maintient l'appareil dans le lit du vent.Its shape is cylindrical in its central part (it) emiSoitant parflitenent the generator; flared in a truncated cone at the front and rear. (5 and 6)
A rear tailplane (8) keeps the device in the wind bed.

L'appareil pivote sur un support, mat unique ou tripode, par l'intermédiaire d'un axe ou d'une couronne double montée sur roulements (7).The device pivots on a support, single mat or tripod, by means of an axis or a double crown mounted on bearings (7).

Les contacts électriques sont assurés par une double piste circulaire isolée et deux patins, le tout monté sur l'axe ou la couronne.The electrical contacts are ensured by a double insulated circular track and two pads, all mounted on the axis or the crown.

Un frein électrique peut être monté pour assurer la régulation de la vitesse de rotation et limiter éventuellement le régime maximum. An electric brake can be fitted to regulate the speed of rotation and possibly limit the maximum speed.

Il est monté (9) sur l'axe de la roue à ailettes et solidaire de celleci. It is mounted (9) on the axis of the impeller and integral with it.

Un boitier régulateur aiguille le courant débité à partir d'une certaine valeur, en partie vers le frein électrique, utilisant le principe des courants de Foueault. A regulator unit directs the current output from a certain value, in part towards the electric brake, using the principle of Foueault currents.

La deuxième variante concernant les aéro-générateurs de faible puissance consiste à utiliser les mêmes principes : roue à ailettes et capotage.The second variant concerning low power air generators consists in using the same principles: impeller and cowling.

Mais une couronne dentée (10) est fixée sur le pourtour de la roue à ailettes et entraine un alternateur (11) fixé à l'extérieur le long de la partie cylindrique.However, a toothed ring (10) is fixed on the periphery of the impeller and drives an alternator (11) fixed outside along the cylindrical part.

Un pignon fixé sur son axe, engrenant sur la couronne, assure sa rotation.A pinion fixed on its axis, meshing on the crown, ensures its rotation.

Le frein électrique est construit selon le même schéma que l'alternateur prévu pour les gros appareils, son volume intérieur étant vide.The electric brake is built according to the same diagram as the alternator intended for large devices, its interior volume being empty.

L'appareil peut être utilisé comme ventilateur, le générateur devenant alors moteur électrique.The device can be used as a fan, the generator then becoming an electric motor.

La figure I du dessin annexé est une vue en coupe longitudinale du dispositif concernant les appareils de forte puissance.Figure I of the accompanying drawing is a longitudinal sectional view of the device for high power devices.

Parmi les applications les plus interessantes de l'invention, on peut citer la production individuelle d'électricité pour les habitations ou exploitations isolées où la production d'électricité pour des unités plus importantes éloignées de toute source commode d'énergie. Among the most interesting applications of the invention, there may be mentioned the individual production of electricity for isolated dwellings or farms or the production of electricity for larger units far from any convenient source of energy.
