Abstract

The turbine which may be used in flowing water or driven by air power or gases, has a circle of adjustable blades (1 to 6) mounted between circular end plates. Each blade can be rotated about an axis through its centre, and the blades rotate the end plates about an axis through their centre. Each blade is tilted about its axis to be at its most favourable angle when in line with the maximum force of the flow acting against it. This flow force can be increased by a guide plate at the entry side. Mounted on the end of each blade axis is a gear pinion which meshes with other pinions to form a gear train to control the angle of tilt of the blades during rotation.

Description

La présente invention concerne un modèle de turbine à pales orientables,dite à double effet,pouvant travailler dans des fluides à vitesse relativement faible,avec un maximum de rendement. The present invention relates to a turbine model with steerable blades, called double-acting, which can work in fluids at relatively low speed, with maximum efficiency.

Cette turbine est destinée à fonctionner dans tous les èlèments fluides ou gazeux animés d'un mouvement rectiligne,et à convertir ce mouvement en énergie mécanique susceptible d'actionner des machines d'utilisation ou de reconvertion. This turbine is intended to operate in all fluid or gaseous elements animated by a rectilinear movement, and to convert this movement into mechanical energy capable of actuating machines for use or conversion.

Jusqu'a présent,ce role était rempli par différents types d(éoliennes,roues å aubes ou à godet,ou turbines dont le rendement demeurait assez faible. Until now, this role has been fulfilled by different types of wind turbines, paddle or bucket wheels, or turbines whose performance remained quite low.

La présente turbine à la propriété de voir ses pales s'orienter de telle sorte qu'elles sont en permanence en position de travail.D'autre part,ses pales s'opposent en partie au passage du courant.Ceci a pour effet de convertir directement la vitesse du fluide en pression.Cette pression s'exerce sur la partie retournée de la pale opposee au courant,et provoque un couple de rotation de la pale sur elle même.(fig 5 a et b)
Ce couple vient,par les pignons,s'ajouter au couple provoqué par l'incidence me des pales.The present turbine has the property of having its blades orientated so that they are permanently in the working position, and on the other hand, its blades partially prevent the flow of current. directly the speed of the fluid under pressure. This pressure is exerted on the inverted part of the blade opposite to the current, and causes a rotation torque of the blade on itself. (fig 5 a and b)
This couple comes, through the pinions, to add to the torque caused by the incidence me of the blades.

La partie arrière de la pale augmente l'incidence par le tourbillon qu'elle provoque.(fig 6)
La partie avant de la pale crée une dépression qui agit sur le couple de la pale,et canalise le flux vers la pale suivante.The rear part of the blade increases the incidence by the vortex that it causes. (Fig 6)
The front part of the blade creates a depression which acts on the blade torque, and channels the flow to the next blade.

Ceci-assure un rendement optimum. This-ensures optimum performance.

La turbine peut ètre intégrée dans une conduite forcée,ce qui augmente la pression et la vitesse.A noter qu'il est préférablespar un déflecteur,de canaliser le flux vers les pales qui offrent la plus grande incidence.(an bas sur les fig.l et 4)
Elle peut fonctionner dans toute les positions-.En position verticale,les pales peuvent s'orienter à l'aide d'un gouvernail agissant sur le pignon central qui,n'étant pas solidaire de l'axe,agit sur l'orientation relative des pales.Le gouvernail est muni d'un dispositif mécanique ou électrique permettant de faire varier son incidence en cas de surcharge du fluide,ou de l'appareil d'utilisation.The turbine can be integrated in a penstock, which increases the pressure and the speed. Note that it is preferable by a deflector, to channel the flow towards the blades which offer the greatest incidence (at bottom on fig. l and 4)
It can operate in any position. In the vertical position, the blades can be oriented using a rudder acting on the central pinion which, not being integral with the axis, acts on the relative orientation The rudder is fitted with a mechanical or electrical device making it possible to vary its incidence in the event of fluid overload, or of the device of use.

Dans toutes les autres positions,le pignon central peut ètre ou fixé au bati,ou asservi par un mécanisme quelconque. Ceci permet de l'utiliser pour des fluides ayant un mouvement de va et vient,ou irréguliers en direction. In all other positions, the central pinion can be either fixed to the frame, or controlled by any mechanism. This allows it to be used for fluids with a back and forth movement, or irregular in direction.

La surface des pales est très supérieure à la surface que l'appareil présente au liquide ou autre fluide. The surface of the blades is much greater than the surface that the device presents to the liquid or other fluid.

La turbine est composée de deux ou plusieurs flasques articulées par roulements ou palliers sur un pivot central,lui même fixé sur un bati. The turbine is composed of two or more flanges articulated by bearings or bearings on a central pivot, itself fixed on a frame.

Ces flasques portent sur leur périphérie les roulements ou palliers des pales.Les pales en dimentièns et nombre variable, sont d'une très grande résistance,et capables de supporter des pressions considérables. These flanges carry on their periphery the bearings or bearings of the blades. The blades in dimentiens and variable number, are of a very great resistance, and able to support considerable pressures.

Les axes des pales sont munis à leurs extrémités de pignons reliés au pignon central par des pignons intermédiaires. The axes of the blades are provided at their ends with pinions connected to the central pinion by intermediate pinions.

Le rapport pignon pale /pignon central est de 2/1. The pale gear / center gear ratio is 2/1.

Les pignons peuvent etre remplacés sur de plus petits modèles par des courroies crantées ou chaines.lténergie fournie est recueuillie sur une des flasques par un moyen approprié. The sprockets can be replaced on smaller models by toothed belts or chains. The energy supplied is collected on one of the flanges by an appropriate means.

Le fonctionnement de cet appareil,d'une extrème simplicité, se comprend aisément à la lecture des plans.(fig 1 et 4)
La forme des pales,et leur comportement dans le fluide se comprennent dans les figures 5 a et b,ainsi que dans la fig.6
La structure de cet appareil peut etre tres variable selon le milieu dans lequel il est destiné à travailler.Les dimentions de la turbine,le nombre et la surface des pales sont à adapter à l'utilisation demandée.The operation of this extremely simple device is easily understood when reading the plans (fig 1 and 4)
The shape of the blades, and their behavior in the fluid can be understood in figures 5 a and b, as well as in fig. 6
The structure of this device can be very variable depending on the environment in which it is intended to work. The dimensions of the turbine, the number and the surface of the blades are to be adapted to the required use.

Nous nous contenterons ici d'en expliquer le fonctionnement dans une situation conforme aux fig 1 et 4. We will content ourselves here with explaining how it works in a situation in accordance with Figs 1 and 4.

En considérant un courant venant de droite et se dirigeant vers la gauche: la pale 1 a une incidence faible et transforme le mouvement du fluide en couple C1 dirigé vers le bas*Sen couple propre s'y ajoute.La pale 2 a une plus forte incidence et produit une poussée C2 vers le bas et la gauche;son couple propre s'y ajoute.I en est de même des pales 3,4,5 et6qui provoquent la rotation par leur propre couple,et recoivent du fluide des poussées C3,C4,C5,alors que la pale 6 remonte le courant sans lui apposer de résistance. Considering a current coming from the right and going towards the left: the blade 1 has a weak incidence and transforms the movement of the fluid into couple C1 directed downwards * Sen own torque is added to it. The blade 2 has a stronger incidence and produces a thrust C2 down and to the left; its own torque is added to it. The same is true of the blades 3,4,5 and 6 which cause rotation by their own torque, and receive fluid from the thrusts C3, C4, C5, while the blade 6 goes upstream without adding resistance to it.

Cette turbide peut etre installée en milieu liquide.(énergie marémotrice,courants marins,fleuves,etc...) ou en milieu gazeux: acheminées importantes,refroidisseurs,plateformes d'immeubles,
incorporés à l'architecture des batiments situés en bord de mer, etc...) comme source d'énergie facilement transformable.This turbid can be installed in a liquid medium (tidal energy, sea currents, rivers, etc.) or in a gaseous medium: large routes, coolers, building platforms,
incorporated into the architecture of buildings located by the sea, etc.) as an easily transformable source of energy.

Son prix de revient réduit facilite son amortissement.  Its reduced cost price facilitates its depreciation.
