Abstract

The device has an air inlet (5) formed at the center of a central axle of an intra-animated rotating propeller (4) or a turbine of a windmill to allow passage of air via an interior of a blade of the propeller. An air outlet (3) is formed at an end of the blade to discharge the air for exerting natural pressure on the propeller. An air baffle (13) is arranged on the air outlet. A funnel type wind sensor is fixed on the air inlet.

Description

La présente invention concerne un dispositif conçu pour augmenter la vitesse de rotation, ainsi que la puissance des hélices, pales, turbine, par le vent ou par l'eau. The present invention relates to a device designed to increase the speed of rotation, as well as the power of the propellers, blades, turbine, wind or water.

La rotation d'une hélice est traditionnellement effectuée par le vent, qui soulève la pale fixée sur son axe. The rotation of a propeller is traditionally performed by the wind, which raises the blade fixed on its axis.

Ce mouvement est facilité par la position oblique de la pale face au vent. Ce mouvement se décompose en deux forces : la force dite de portance lorsque le vent souffle sur la pale oblique, puis la force dite de traînée lorsque le vent pousse la pale vers l'arrière. Ce processus ordinaire comporte énormément de pertes. This movement is facilitated by the oblique position of the blade facing the wind. This movement breaks down into two forces: the so-called lift force when the wind blows on the oblique blade, then the so-called drag force when the wind pushes the blade towards the rear. This ordinary process involves a lot of losses.

Le dispositif selon l'invention permet de remédier à ces inconvénients. 10 En effet, deux caractéristiques apportent une solution efficace. La première concerne un orifice d'entrée de vent, pouvant se situer au centre de l'éolienne ou à quelques centimètres de ce dernier. Il permet donc au vent de passer par l'intérieur de la pale. The device according to the invention overcomes these disadvantages. Indeed, two features provide an effective solution. The first concerns a wind inlet, which can be located in the center of the wind turbine or a few centimeters from it. It allows the wind to pass through the inside of the blade.

La seconde caractéristique montre un orifice de sortie de vent à l'extrémité de la 15 pale. Ce dispositif crée un "courant d'air" naturel et donc une énergie supplémentaire, qui -en sortant - augmente d'autant la vitesse de rotation et la puissance. Celle-ci est alors supérieure à celle d'une hélice classique, en tirant au maximum partie de l'énergie du vent. The second feature shows a wind outlet at the end of the blade. This device creates a natural "air flow" and therefore an additional energy, which - when leaving - increases all the speed of rotation and the power. This is then greater than that of a conventional propeller, by making the most of the wind energy.

20 Selon des modes particuliers de réalisation, l'orifice d'entrée de l'air (ou les orifices) peut se trouver au centre de l'éolienne ou à quelques centimètres de celui-ci sur la pale, puis un orifice de sortie de l'air se trouve à l'extrémité de la pale. According to particular embodiments, the air inlet orifice (or the orifices) may be in the center of the wind turbine or a few centimeters of it on the blade, and then an outlet orifice of the air is at the end of the blade.

Selon des modes particuliers de fabrication, un déflecteur d'air peut se trouver sur 25 l'orifice de sortie de vent, afin d'augmenter la vitesse de rotation. According to particular modes of manufacture, an air deflector may be located on the wind outlet orifice, in order to increase the speed of rotation.

Le dessin en annexe illustre l'invention : The drawing in the appendix illustrates the invention:

* figure 1/1 : hélice à rotation intra-animée ou turbine * déflecteur : 13 * hélice : 4 ou turbine 30 * entrée du vent : 5 * sortie du vent : 3 * figure 1/1: intra-animated rotating propeller or turbine * deflector: 13 * propeller: 4 or turbine 30 * wind inlet: 5 * wind outlet: 3

La figure représente le dispositif de l'invention, en référence à cette figure. Le dispositif comporte un orifice (5), dont le diamètre varie avec le type de pale (4). La pale est donc creuse jusqu'à son extrémité, où peut se trouver facultativement un 35 déflecteur d'air (13), sur lequel le vent en sortant exerce une pression qui augmente la puissance et la vitesse de rotation de l'hélice (4) ou turbine. The figure shows the device of the invention, with reference to this figure. The device comprises an orifice (5), the diameter of which varies with the type of blade (4). The blade is thus hollow to its end, where an air baffle (13) can optionally be located, on which the outgoing wind exerts a pressure which increases the power and the speed of rotation of the propeller (4). ) or turbine.

Selon une variante non illustrée, un capteur de vent type entonnoir peut être fixé sur l'orifice d'entrée d'air. 1 Selon une autre variante non illustrée, l'orifice (ou les orifices de rentrée d'air) peut se trouver à quelques centimètres du centre de l'axe cenral de l'éolienne ; c'est-à-dire sur la pale elle-même qui est creuse jusqu'à son extrémité où se trouve l'orifice de sortie d'air (3). According to a variant not illustrated, a funnel-type wind sensor may be attached to the air inlet port. 1 According to another variant not shown, the orifice (or the air intake holes) may be a few centimeters from the center of the central axis of the wind turbine; that is to say on the blade itself which is hollow to its end where is the air outlet port (3).

Le dispositif selon l'intervention est particulièrement destiné à augmenter la vitesse de rotation ainsi que la puissance des éoliennes ou des turbines pour la fabrication d'électricité, le pompage de l'eau, le refroidissement de moteurs de véhicules, la fabrication d'électricité pour des véhicules électriques, pour les aéronefs. The device according to the intervention is particularly intended to increase the rotation speed and the power of wind turbines or turbines for the manufacture of electricity, the pumping of water, the cooling of vehicle engines, the manufacture of electricity for electric vehicles, for aircraft.

Selon une nouvelle variante non illustrée, la rotation de l'hélice peut s'effectuer direc- tement par de l'air comprimé grâce à un branchement par l'orifice (5). Cette turbine comprendra une pale sur deux positionnée à l'envers, ce qui n'engendrera pas de déplacement d'air mais suscitera une augmentation de la vitesse de rotation, avec une quanitité d'air propulsé infime. According to a new variant not shown, the rotation of the helix can be carried out directly by compressed air through a connection through the orifice (5). This turbine will include a blade on two positioned upside down, which will not cause air displacement but will cause an increase in the speed of rotation, with a small amount of air propelled.
