Definitions
- Modular Stato-Wind with low noise level The various winds sweeping the earth's surface constitute an essentially fluctuating atmospheric phenomenon. They can be of inconsistent direction, intensity and shape and can be exerted in squalls, gusts, tornadoes, cyclones or by more or less irregular breaths. Finally, their peak energy is often destructive as irrefutably demonstrate all the failures attributable to the propeller / pylon system during a period spanning 1/2 century. Furthermore, the power collected cannot exceed 0.38 V 3 (W / m 2 ) and, in the best of cases: that is to say when the speed V (m / s) in the wake of the propeller falls to 1/3 of the wind speed.
- This stato-wind is based on the association of concomitant effects that the wind exerts on any static obstacle of cylindrical conformation with vertical axis (horizontal section Fig.I). However, these effects also appear when the obstacle is a static peripteral structure, according to the horizontal section (Fig.2).
- a frontal dynamic overpressure SP
- DL high intensity lateral depression
- D1 less intense lateral depression
- Ds wake depression
- the applied technology consists in taking advantage, not only, of the frontal dynamic overpressure (SP) which is exerted upstream of the turbine blades, know again, of the sum of the depressions (DL + Dl + Ds), lower than the pressure static atmospheric.
- stato-wind constitutes either a mechanical generator, either an electric generator, or a stato-wind heat pump which draws heat from the atmosphere through the kinetic energy of the winds.
- This stato-wind is developed so that the impetuosity of the gusts undergoes spreading with modification of speed and pressure in order to make them indestructive.
- the internal path traversed by the wind takes on the schematic formation (Fig. 3) of two venturis in series which are successively dependent on two deflecto-convergent (I and 2) and spiro-divergent (3 and 4).
- the first venturi taking effect on the upstream front in dynamic overpressure, ends in a spreading chamber where the passage section at the neck is several times less than the upstream entry section. Beyond this threshold, the flow flows spirally between two concentric steps and ends at the right of the turbine blades where the inlet section is several times larger than at the spreading neck. At this level, the initial shape and speed of the flow are spread and the pressure has increased. This is how the wind flow approaches in excellent conditions the second venturi formed by the turbine blades and a peripheral step. .
- the profile located between two successive blades, of deflecting convergent conformation allows an adiabatic expansion with final speed of flight slightly higher than the opposite tangential speed of the reaction blades. Then, the flow spirally flows on the internal inclined plane of the peripheral step which leads to the downstream areas in dynamic depression.
- This stato-wind turbine constituting a compact and well balanced low noise level construction, is obtained by molding of expanded materials.
- an ancient agreement ensures this building a tenacity resistant to the strongest storms.
- the curved obliqueness of the wings determines the distribution of two complementary functions.
- Each of these two functions is exercised respectively on one of the two faces of a circular bowl (6) arranged horizontally.
- this bowl hollowed out in its center by the spreading chamber (7), is taken in sandnich between two circular flanges, one underlying ( ⁇ ) constituting the base of the converging injection nozzles, the another (9) covering the turbine duct (10) from above.
- the horizontal bowl constitutes in its hollowed-out center an energy transfer chamber (16) of different configuration according to three versions.
- one or two coaxial turbines open the way to three variants: one simplified with low power, the other two more elaborate with medium and high power.
- the regulation of the peaks of gusts is effected by means of the three circular steps arranged concentrically, between which, the gusts spread out in a flow uniformly distributed over all the turbine blades .
- a central turbine (17) of medium or high power (FIG. 7) constituting a flywheel, accumulates the kinetic energy of the gusts and restores it in the form of a regularized wind flow which then leads either to a medium power co-axial turbine, i.e. several high power turbines (18) arranged in the bowl all around the chamber spreading (Fig. 8 and 9).
- the regulating turbine is also stalled on the shaft of an electric generator, not ex cited in winds less than 25m / s, but which is excited beyond this threshold.
- This excitation proportional to the kinetic energy of the wind thus authorizes the production of alternating or direct currents depending on the desired application (heating, recharging of batteries or dissociation of water into hydrogen, or even the creation of small complexes for the production of 'a synthetic fuel, such as methanol obtained by water, wind and C0 2 always present in the air. Consequently, the steps in the first variant and the regulating turbine in the other two, constitute in the three cases the essential elements of large production in stormy winds or very high flow.
- the three variants are provided with a crown of leaves which are articulated on the extradorsal environment of each wing. These leaves are more or less repelled by the wind.
- the leaves not subject to direct wind, are kept closed by the double effect of a return spring and the dynamic downstream depression. The leaves opposing the downstream sound diffusion, then in zero wind provide protection against any animal or human intrusion.
- These leaves also maintain a flow inversely proportional to the wind speed by opening more or less the motor injection section. Therefore, the multiplying factor is high for low speed winds to be only 4, for high speed winds.
- these leaves are controlled by oleo-pneumatic cylinders in order to optimally regulate the high power flow. In this case, the opening of the leaves is subject to wind pressure and remains locked in zero wind.
- the pilot element is the angular speed of each corresponding turbine.
- a generator (19) wedged on the shaft (20) of the turbine, produces excitation currents by scanning two polar masses of a permanent magnet of circular conformation (21).
- a double armature is fitted with hypermagnetic screens (22) equidistant behind each of which, the conductors which are housed therein are perfectly protected from the uniform magnetic flux.
- Each of these screens takes the place of one notch tooth removed out of four.
- this double armature is wound, the portion of conductor loops housed between two consecutive teeth is subjected to the uniform flux, while the bundle of conductor loops hidden by the screen is magnetically isolated.
- the rotary excitation armature is also dependent on a winding (23) which superimposes its field on that of the magnet whose increasing excitation is under the control of the voltage of the main armature (24) which increases with the force of the wind.
- the resistive torque is reduced to the exciting action of a single magnet acting on a mobile excitation winding, connected in series with the winding of the main inductor (25). Then, for a minimum wind of 5 to 8m / s, the main inductor then excited, generates in its turn on the main armature, a current proportional to the energy of the wind in alternative or continuous form.
- the new configuration is refined (Fig.I2), the internal flow is greatly improved and the turbine blades are larger in order to compensate for less engine flow. energetic.
- a transfer chamber constitutes the seat of an aerovortex which, once started, maintains a strong central depression towards which the wind flows from the driving nozzles are accelerated.
- the two frustoconical elements in fact constitute an intake variator increasing or limiting the flow rate by a modification of wind intake angle.
- This variation is obtained by means of an omnifunctional aerostabilizing device (28) subject to said hemi-frusto-conical elements.
- This aerostabilizing device (diagram, Fig.13), comprises a fin with two asymmetrical leaves (29 and 30), coaxial articulated and juxtaposed, one against the other by zero wind. The asymmetry of the two leaves drift stabilizes in the wind over the bed aérovor tex, because they are unevenly exposed to the dynamic pressure SV 2/2, thereby generating an anti-torque opposing the torque that s' exercise this in the said room.
- these two drift wings deploy on an arc of 120 ° when the wind is exerted according to the schematic views, (Fig.14 and Fig.15).
- This action is carried out by means of a front shield (31) integral with the two wing wings.
- This shield is constituted by two arms (32) which extend each wing wing beyond the joint (27). These two arms are respectively extended by an articulated flap (33). linked as soon as the wind exerts a frontal thrust, these two flaps, accompanying the two arms of the shield, are deployed by partially masking the drift located behind the axis of articulation, simultaneously causing the movement of the leaves on an arc of 120o. This deployment thus modifies the angle of admission of the wind into the aerovortex chamber.
- the shield when the wind exceeds a predetermined threshold depending on a site, the shield, being abutted by the own deployment of the two leaves, folds in turn, thus unmasking a larger area of the said leaves.
- the opening angle can be reduced from 0 ° to 120 ° or vice versa by the simple set of fins, a shield and return springs.
- stato-wind turbine replaces a multitude of universal easements where energy saving requires it.

Abstract
In this highly resistant modular wind turbine having a flat configuration, advantageously substituting the helix-tower, the wind squalls, which are generally destructive, spread schematically in a double venturi in series defined, at the leading front, by a deflecto-convergent space followed, upstream of one or a plurality of turbines, by a spiro-divergent space. Then, a second deflector-convergent space, embodied by the blades of the turbine, is also followed by another spiro-divergent trailing space. Thus, the wind flow, coming from any direction, is under the dependence of a peripteral construction in which vertical wings (5), curved in the horizontal plane, canalise said flow from the front area, in a dynamic overpressure, towards a spreading chamber (7) from which it accesses to a set of concentric baffles (12, 13 and 14), embodied by an intermediary sink (6) which brings it back through the turbine blades towards the peripheral area wherein a dynamic depression prevails. Further, said sink is sandwiched between two horizontal flanges, so-called trailing (9) and base (8) flanges which define, in the upper side, the turbine conduit (10) and, in the lower side, the drive nozzles. Finally, according to the power provided, the shaft of one or a plurality of turbines drives either an electric generator or any mechanical receiver.
Description
Stato-Eolien Modulaire à bas niveau sonore. Les divers vents balayant la surface terrestre constituent un phénomène atmosphérique essentiellement fluctuant. Ils peuvent être de direction, d'intensité et de forme inconstantes et s'exercer en bourrasques, rafales, tornades, cyclones ou par souffles plus ou moins irréguliers. Enfin, leur énergie de crête est souvent destructrice comme le démontrent irréfutablement tous les échecs imputables au système hélice/pylone durant une période s'étalant sur 1/2 siècle. Par ailleurs, la puissance recueillie ne peut dépasser 0,38 V3(W/m2) et, cela dans le meilleur des cas: c'est à dire lorsque la vitesse V(m/s) dans le sillage de l'hélice tombe au 1/3 de la vitesse du vent.Modular Stato-Wind with low noise level. The various winds sweeping the earth's surface constitute an essentially fluctuating atmospheric phenomenon. They can be of inconsistent direction, intensity and shape and can be exerted in squalls, gusts, tornadoes, cyclones or by more or less irregular breaths. Finally, their peak energy is often destructive as irrefutably demonstrate all the failures attributable to the propeller / pylon system during a period spanning 1/2 century. Furthermore, the power collected cannot exceed 0.38 V 3 (W / m 2 ) and, in the best of cases: that is to say when the speed V (m / s) in the wake of the propeller falls to 1/3 of the wind speed.
Par conséquent, l'expérimentation a nettement démontré que 1 'aéro moteur à hélice s'articulant sur pylône, est impropre à l'exploita tion des vents de haut niveau énergétique, et cela, malgré la mise en drapeau de ses pales, réduisant singulièrement leur efficacité.Consequently, experience has clearly shown that the aero propeller motor hinging on a pylon is unfit for the exploitation of high energy winds, and this, despite the feathering of its blades, considerably reducing their effectiveness.
Or, l'efficacité ne peut être obtenue qu'en utilisant toute la gamme des vents allant jusqu'aux tempêtes.However, efficiency can only be obtained by using the whole range of winds up to storms.
Pour étayer cette affirmation, il n'y a qu'à considérer l'écoulement d'un "tube" d'air de Im2 de section dont la vitesse V varie de 18 km/h à 144 km/h, soit de 5m à 40m/s. Sachant qu'un m3 d'air pèse environ I, 290kg, la formule de son énergie cinétique en Watts/seconde peut s'écrire:To support this assertion, we only have to consider the flow of an air "tube" of Im 2 of section whose speed V varies from 18 km / h to 144 km / h, or 5m at 40m / s. Knowing that a m 3 of air weighs approximately I, 290 kg, the formula of its kinetic energy in Watts / second can be written:
E (watts) = (I.290.V.). V2/2 - I,290 V3/2. Ainsi, pour des vitesses de vents de 5,10,20 et 40m/s, l'énergie cinétique de ces quatre paliers de vitesse est:E (watts) = (I.290.V.). V 2/2 - I, 290 V 3/2. Thus, for wind speeds of 5,10,20 and 40m / s, the kinetic energy of these four speed steps is:
5a/s- - - - - - - - - - - - - - - W = 80 IOm/s- - - - - - - - - - - - - - - W = 6005a / s- - - - - - - - - - - - - - - W = 80 IOm / s- - - - - - - - - - - - - - - - W = 600

20m / s - - - - - - - - - - - - - - W = 5000 40m / s - - - - - - - - - - - - - - W = 40000
Par conséquent, de 5 à 40a/s, il apparait qu'une vitesse e vent (40/5) =8 fois plus grande possède en fait une énergie cinétique (40000/80) =500 foie plus élevée. Ces valeurs, constituent l'énergie de crête que l'on peut étaler dans le temps, mais à une valeur plus faible. Or, l'énergie cinétique des vents peut être interceptée avec un rendement très proche de l'unité. Pour cela, il suffit que la vitesse d'éjection du flux éolien soit relativement nulle à la sortie des aubes de turbine.
II faut donc recourir à une construction qui remplit cette condition. Cette condition est remplie par le truchement adéquat d ' écoulements dynamiques sous carénage. Or, de tels écoulements autorisent, non seulement, des modifications de pression et de vitesse, mais encore , des variations theπnocinétiques. Ainsi , lorsqu'un écoulement s 'effectue dans un conduit du type convergent -divergent, il se produit au droit de l'étranglement non seulement, un effet de détente, mais encore, un refroidissement avec gain cinétique tel que Mv2 = mV2, sachant que v<V et M>m. Par ce moyen, les aubes de turbine à réac- tion convertissent endothermiquement, par détente adiabatique réversible, les 9/10 de l ' énergie cinétique des vents faibles, moyens , forts, très forts, voire impétueux, dont l 'exploitation exige une forme d'approche conforme à l ' efficacité, la ténacité et la fiabilité de l 'installation. Hais dans le cadre de l 'efficience économi- que, il convient d' éviter le gigantisme , car le prix de revient du Watt-installé croît en fonction du cube des proportions.il convient également de ne point rechercher l 'autonomie car cette forme d' énergie doit être utilisée nécessairement sur place et travailler en complémentarité des moyens énergétiques usuels. Par ailleurs, il est irrationnel de promouvoir la production de plusieurs MW d' énergie en un point fixe, pour les redistribuer en d'autres lieux où le vent est également présent.Consequently, from 5 to 40a / s, it appears that a wind speed (40/5) = 8 times greater actually has kinetic energy (40000/80) = 500 higher liver. These values constitute the peak energy that can be spread over time, but at a lower value. However, the kinetic energy of winds can be intercepted with a yield very close to unity. For this, it is sufficient that the ejection speed of the wind flow is relatively zero at the outlet of the turbine blades. It is therefore necessary to resort to a construction which fulfills this condition. This condition is fulfilled by means of dynamic flows under fairing. However, such flows allow, not only, changes in pressure and speed, but also, kinetic variations. Thus, when a flow takes place in a convergent-divergent type conduit, there occurs at the throttling not only, an expansion effect, but also, a cooling with kinetic gain such that Mv 2 = mV 2 , knowing that v <V and M> m. By this means, the reaction turbine blades convert endothermically, by reversible adiabatic expansion, the 9/10 of the kinetic energy of weak, medium, strong, very strong, even impetuous winds, the exploitation of which requires a form approach consistent with the efficiency, tenacity and reliability of the installation. But in the context of economic efficiency, it is advisable to avoid gigantism, because the cost price of the Watt-installed increases according to the cube of the proportions. It is also advisable not to seek autonomy because this form energy must necessarily be used on site and work in addition to the usual energy resources. Furthermore, it is irrational to promote the production of several MW of energy at a fixed point, to redistribute them in other places where the wind is also present.
Ceci étant posé, la reconversion de toute l'énergie éolienne en énergie utilisable, répondant aux conditions précitées, s 'effectue au moyen du présent stato-éolien modulaire à bas niveau, sonore;This being said, the conversion of all wind energy into usable energy, meeting the above conditions, is effected by means of this modular low-noise, stato-wind turbine;
Ce stato-éolien est fondé sur l 'association d'effets eoncomittants qu'exerce le vent sur tout obstacle statique de conformation cylindrique à axe vertical (coupe horizontale Fig.I). Or, ces effets se manifestent aussi lorsque l 'obstacle est un édifice périptère stati- que, selon la coupe horizontale (Fig.2) .This stato-wind is based on the association of concomitant effects that the wind exerts on any static obstacle of cylindrical conformation with vertical axis (horizontal section Fig.I). However, these effects also appear when the obstacle is a static peripteral structure, according to the horizontal section (Fig.2).
Bans ce dernier cas, ces effets sont: une surpression dynamique frontale (SP ) , une dépression latérale de forte intensité (DL) , une dépression latérale d'intensité moindre (D1) , diamétralement opposée à la première et enfin une dépression de sillage (Ds) , d'intensité moyenne. la technologie appliquée consiste à tirer profit, non seulement, de la surpression dynamique frontale (SP) qui s ' exerce en amont des aubes de turbine, sais encore, de la somme des dépressions (DL+Dl+Ds) , inférieure à la pression atmosphérique statique.
Ainsi , en s ' écoulent de la zone en surpression vers les zones en dépression dynamique, le flux éolien traverse les aubes de turbine, tout en se détendant avant d'être éjecté. La détente adiabatique réversible de l 'air ainsi canalisé se tra duit par un net refroidissement proportionnel au rapport SP/DP . La chaleur ainsi convertie se trouve sous forme d ' énergie cinétique dans l 'arbre de turbine. Or, cette énergie cinétique pouvant se convertir en force motrice, en électricité et l ' électricité en chaleur, il est évident que le présent stato-éolien constitue, soit un généra teur mécanique, soit un générateur électrique, soit une thermopompe stato-éolienne qui puise la chaleur dans l 'ambiance par l 'intermédiaire de l ' énergie cinétique des vents.In the latter case, these effects are: a frontal dynamic overpressure (SP), a high intensity lateral depression (DL), a less intense lateral depression (D1), diametrically opposite to the first and finally a wake depression ( Ds), of medium intensity. the applied technology consists in taking advantage, not only, of the frontal dynamic overpressure (SP) which is exerted upstream of the turbine blades, know again, of the sum of the depressions (DL + Dl + Ds), lower than the pressure static atmospheric. Thus, by flowing from the overpressure zone towards the zones with dynamic depression, the wind flow crosses the turbine blades, while relaxing before being ejected. The reversible adiabatic expansion of the air thus channeled results in a net cooling proportional to the SP / DP ratio. The heat thus converted is found in the form of kinetic energy in the turbine shaft. Now, this kinetic energy being able to convert into motive force, into electricity and electricity into heat, it is obvious that the present stato-wind constitutes either a mechanical generator, either an electric generator, or a stato-wind heat pump which draws heat from the atmosphere through the kinetic energy of the winds.
Ce stato-éolien est élaboré de sorte que l 'impétuosité des rafales subisse un étalement avec modification de vitesse et de pression afin de les rendre indestructrices.This stato-wind is developed so that the impetuosity of the gusts undergoes spreading with modification of speed and pressure in order to make them indestructive.
A cet effet, le trajet interne que parcourt le vent revêt la con formation schéaatique(Fig.3) de deux venturis en série qui sont successivement sous la dépendance de deux domaines déflecto-convergent (I et 2) et spiro-divergent (3 et 4) . Le premier venturi, prenant effet sur le front d'amont en surpression dynamique , aboutit dans une chambre d' étalement où la section de passage au col est plusieurs fois inférieure à la section d ' entrée d'amont. Au delà de ce seuil , le flux s ' écoule spiral βment entre deux redans concentriques et aboutit au droit des aubes de turbine où la section d'arrivée est plusieurs fois plus grande qu 'au col d' étalement. A ce niveau, la forme et la vitesse ini tiales du flux sont étalées et la pression s'est accrue, C 'est ainsi que le flux éolien aborde dans d'excellentes conditions le second venturi formé par les aubes de turbine et un redan périphérique. Dès lors, le profil localisé entre deux aubes successives, de conformation déflecto convergente, autorise une détente adiabatique avec vitesse finale de fuite légèrement supérieure à la vitesse tangentielle inverse des aubes à réaction. Ensuite , le flux s' écoule spiralement sur le plan incliné interne du redan périphérique qui débouche sur les zones d'aval en dépression dynamique.To this end, the internal path traversed by the wind takes on the schematic formation (Fig. 3) of two venturis in series which are successively dependent on two deflecto-convergent (I and 2) and spiro-divergent (3 and 4). The first venturi, taking effect on the upstream front in dynamic overpressure, ends in a spreading chamber where the passage section at the neck is several times less than the upstream entry section. Beyond this threshold, the flow flows spirally between two concentric steps and ends at the right of the turbine blades where the inlet section is several times larger than at the spreading neck. At this level, the initial shape and speed of the flow are spread and the pressure has increased. This is how the wind flow approaches in excellent conditions the second venturi formed by the turbine blades and a peripheral step. . Consequently, the profile located between two successive blades, of deflecting convergent conformation, allows an adiabatic expansion with final speed of flight slightly higher than the opposite tangential speed of the reaction blades. Then, the flow spirally flows on the internal inclined plane of the peripheral step which leads to the downstream areas in dynamic depression.
Ce stato-éolien, constituant une construction à bas niveau sonore compacte et bien équilibrée, est obtenu par moulage de matériaux expansés. D 'autre part, un contrerentement arαtuel assure à cet édifice
une ténacité résistant aux plus fortes tempêtes.This stato-wind turbine, constituting a compact and well balanced low noise level construction, is obtained by molding of expanded materials. On the other hand, an ancient agreement ensures this building a tenacity resistant to the strongest storms.
La conformation relativement plate du présent stato-éolien où H=D/5 , représente un édifice périptère dont les ailes verticales (5 ) , disposées sur tout le pourtour, sont légèrement incurvées sur leur plan radial respectif. (Fig. 4,5 et 6) .The relatively flat conformation of this stato-wind where H = D / 5, represents a peripteral building whose vertical wings (5), arranged around the entire periphery, are slightly curved on their respective radial plane. (Figs 4,5 and 6).
Une telle conformation permet l 'interception des vents de toute direction sans le recours à une quelconque orientation.Such a conformation allows interception of winds from any direction without the use of any orientation.
En outre, l 'oblicité incurvée des ailes détermine la répartition de deux fonctions complémentaires. Ainsi, le 1/3 de la surface périphéri que assure la surpression dynamique d'amont, tandis que les autres 2/3 entretiennent la dépression d 'aval. Chacune de ces deux fonctions s'exerce respectivement sur l 'une des deux faces d'une cuvette circulaire (6) disposée horizontalement. Par ailleurs, cette cuvette, évidée en son centre par la chambre d' étalement (7) , est prise en sandnich entre deux flasques circulaires, l 'un sous-jacent(δ) constituant la base des buses convergentes d 'injection, l 'autre (9) coiffant le conduit (10 ) de turbine par le haut. Les deux flasques .circulaires, les ailes verticales, munies en commun d'un redan (II) périphérique de section triangulaire, la cuvette horizontale munie d 'un jeu de redans internes (12 et 13) , un troisième redan intermédiaire (14) , également circulaire, ainsi qu'une couronne de vantaux (15) constituent un ensemble de chicanes d'absorption sonore.In addition, the curved obliqueness of the wings determines the distribution of two complementary functions. Thus, 1/3 of the peripheral surface provided by the upstream dynamic overpressure, while the other 2/3 maintain the downstream depression. Each of these two functions is exercised respectively on one of the two faces of a circular bowl (6) arranged horizontally. Furthermore, this bowl, hollowed out in its center by the spreading chamber (7), is taken in sandnich between two circular flanges, one underlying (δ) constituting the base of the converging injection nozzles, the another (9) covering the turbine duct (10) from above. The two circular flanges, the vertical wings, provided in common with a peripheral step (II) of triangular section, the horizontal bowl provided with a set of internal steps (12 and 13), a third intermediate step (14), also circular, as well as a crown of leaves (15) constitute a set of baffles for sound absorption.
La cuvette horizontale constitue en son centre évidé une chambre de transfert énergétique(l6)de configuration différente selon trois versions. Selon la première et seconde version une ou deux turbines coaxiales ouvrent la voie à trois variantes: l'une simplifiée de faible puissance , les deux autres plus élaborées de moyenne et grande puissance.The horizontal bowl constitutes in its hollowed-out center an energy transfer chamber (16) of different configuration according to three versions. According to the first and second version, one or two coaxial turbines open the way to three variants: one simplified with low power, the other two more elaborate with medium and high power.
Selon la variante simplifiée avec une seule turbine, la régulation des crêtes de rafales, s' effectuent par le truchement des trois redans circulaires disposés concentriquement, entre lesquels, les rafales s'étalent en un flux uniformément réparti sur l 'ensemble des aubes de turbine. Selon la variante plus élaborée, une turbine centrale (17) de moyenne ou forte puissance (Fig.7) , constituant un volant , accumule l ' énergie cinétique des rafales et la restitue sous forme d'un flux éolien régularisé qui entraine ensuite, soit une turbine co axiale de puissance moyenne, soit plusieurs turbines de grande puissance (18) disposées dans la cuvette tout autour de la chambre
d' étalement (Fig. 8 et 9). Dans ces deux derniers cas, la turbine de régulation est aussi calée sur l 'arbre d 'un générateur électrique, non ex cité par vents inférieurs à 25m/s, mais qui est excité au delà de ce seuil. Cette excitation proportionnelle à l'énergie cinétique du vent, autorise ainsi la production de courants alternatifs ou continus selon l 'application recherchée (chauffage, recharge d'accus ou dissociation d'eau en hydrogène, voire même la constitution de petits complexes de production d'un carburant de synthèse, tel le méthanol obtenu par l 'eau, le vent et le C02 toujours présent dans l'air. Par conséquent, les redans dans la première variante et la turbine de régulation dans les deux autres, constituent dans les trois cas les éléments essentiels de grande production par vents de tempêtes ou de très forts débit.According to the simplified variant with a single turbine, the regulation of the peaks of gusts is effected by means of the three circular steps arranged concentrically, between which, the gusts spread out in a flow uniformly distributed over all the turbine blades . According to the more elaborate variant, a central turbine (17) of medium or high power (FIG. 7), constituting a flywheel, accumulates the kinetic energy of the gusts and restores it in the form of a regularized wind flow which then leads either to a medium power co-axial turbine, i.e. several high power turbines (18) arranged in the bowl all around the chamber spreading (Fig. 8 and 9). In these last two cases, the regulating turbine is also stalled on the shaft of an electric generator, not ex cited in winds less than 25m / s, but which is excited beyond this threshold. This excitation proportional to the kinetic energy of the wind, thus authorizes the production of alternating or direct currents depending on the desired application (heating, recharging of batteries or dissociation of water into hydrogen, or even the creation of small complexes for the production of 'a synthetic fuel, such as methanol obtained by water, wind and C0 2 always present in the air. Consequently, the steps in the first variant and the regulating turbine in the other two, constitute in the three cases the essential elements of large production in stormy winds or very high flow.
Comme il a été précédemment indiqué, les trois variantes sont munies d'une couronne de vantaux qui s 'articulent sur le milieu extradorsal de chaque aile. Ces vantaux sont plus ou moins repoussés par le vent. Par contre , les vantaux, non soumi s au vent direct, se maintiennent fermés par le double effet d'un ressort de rappel et de la dépression dynamique d 'aval. Les vantaux s 'o pposant à la diffusion sonore d'aval , puis par vent nul assurent la protection contre toute intrusion-animale ou humaine. Ces vantaux entretiennent aussi un débit inversement proportionnel à la vitesse du vent en ouvrant plus ou moins la section d'injection motrice. De ce fait, le facteur multiplicateur est élevé pour les vents de faible vitesse pour n'être que de 4, pour des vents de grande vitesse. En version élaborée de grande puissance, ces vantaux sont commandés par vérins oléo-pneumatiques afin de régulariser optimal ement le débit de grande puissance. Dans ce cas, l 'ouverture des vantaux est soumise à la pression du vent et reste vérouillée par vent nul.As previously indicated, the three variants are provided with a crown of leaves which are articulated on the extradorsal environment of each wing. These leaves are more or less repelled by the wind. On the other hand, the leaves, not subject to direct wind, are kept closed by the double effect of a return spring and the dynamic downstream depression. The leaves opposing the downstream sound diffusion, then in zero wind provide protection against any animal or human intrusion. These leaves also maintain a flow inversely proportional to the wind speed by opening more or less the motor injection section. Therefore, the multiplying factor is high for low speed winds to be only 4, for high speed winds. In an elaborate version of high power, these leaves are controlled by oleo-pneumatic cylinders in order to optimally regulate the high power flow. In this case, the opening of the leaves is subject to wind pressure and remains locked in zero wind.
En ce qui concerne l ' excitation du ou des générateurs électriques (schéma, Fig.10 ) , l ' élément pilote est la vitesse angulaire de chaque turbine correspondante. A cet effet, un générateur (19) , calé sur l 'arbre (20 ) de la turbine, produit des courants d' excitation par balayage de deux masses polaires d'un aimant permanent de conformation circulaire (21) . Dans ce cas , un double induit est équipé d' écrans hypermagnétiques
(22) équidistants derrière chacun desquels , les conducteurs qui s 'y logent sont parfaitement protégés du flux magnétique uniforme.Regarding the excitation of the electric generator (s) (diagram, Fig.10), the pilot element is the angular speed of each corresponding turbine. To this end, a generator (19), wedged on the shaft (20) of the turbine, produces excitation currents by scanning two polar masses of a permanent magnet of circular conformation (21). In this case, a double armature is fitted with hypermagnetic screens (22) equidistant behind each of which, the conductors which are housed therein are perfectly protected from the uniform magnetic flux.
Chacun de ces écrans , prend la place d 'une dent d'encoche supprimée sur quatre. Ainsi , lorsque cet induit double est bobiné, la partie de boucles de conducteurs logée entre deux dents consécutives se trouve soumise au flux uniforme, alors que le faisceau de boucles de conducteurs cachée par l 'écran est magnétiquement isolé.Each of these screens takes the place of one notch tooth removed out of four. Thus, when this double armature is wound, the portion of conductor loops housed between two consecutive teeth is subjected to the uniform flux, while the bundle of conductor loops hidden by the screen is magnetically isolated.
L 'enroulement de ce double induit (schéma, Fig. II) ; s'effectue de sorte que les conducteurs soumis au flux magnétique soient tous orien tés dans un sens en regard du pôle "Bord" circulaire et de sens contraire, en regerd du pôle "Sud", ce qui implique nécessairement dans les deux cas un sens inverse pour les conducteurs sous écrans hypermagnétiques.The winding of this double armature (diagram, Fig. II); takes place so that the conductors subjected to the magnetic flux are all oriented in one direction opposite the circular "Edge" pole and in the opposite direction, opposite the "South" pole, which in both cases necessarily implies a direction reverse for conductors under hypermagnetic screens.
Outre cet aimant permanent, l 'induit rotatif d'excitation se trouve aussi sous la dépendance d'un enroulement (23) qui superpose son champ à celui de l'aimant dont l'excitation croissante est sous le contrôle de la tension de l 'induit principal (24) qui croît avec la force du vent.In addition to this permanent magnet, the rotary excitation armature is also dependent on a winding (23) which superimposes its field on that of the magnet whose increasing excitation is under the control of the voltage of the main armature (24) which increases with the force of the wind.
Dès lors , à chaque démarrage, le couple résistant est réduit à l 'action excitatrice d'un seul aimant agissant sur un bobinage mobile d'ex citation, connecté en série avec le bobinage de l 'inducteur principal (25) . Ensuite , pour un vent minimum de 5 à 8m/s, l 'inducteur peincipal alors excité, engendre à son tour sur l 'induit principal, un courant proportionnel à l ' énergie du vent sous forme alternative ou continue. Selon la troisième version qui convient à de multiples sites dotés de vents moyens, la nouvelle configuration est affinée (Fig.I2) ,l ' écoulement interne est grandement amélioré et les aubes de turbine sont de plus grandes dimensions afin de compenser un flux moteur moins énergétique. Par ailleurs, une chambre de transfert constitue le siège d'un aérovortex qui, une fois amorcé, entretient une forte dépression centrale vers laquelle s'accélère les flux éoliens provenant des buses motrices.Consequently, at each start-up, the resistive torque is reduced to the exciting action of a single magnet acting on a mobile excitation winding, connected in series with the winding of the main inductor (25). Then, for a minimum wind of 5 to 8m / s, the main inductor then excited, generates in its turn on the main armature, a current proportional to the energy of the wind in alternative or continuous form. According to the third version, which is suitable for multiple sites with medium winds, the new configuration is refined (Fig.I2), the internal flow is greatly improved and the turbine blades are larger in order to compensate for less engine flow. energetic. In addition, a transfer chamber constitutes the seat of an aerovortex which, once started, maintains a strong central depression towards which the wind flows from the driving nozzles are accelerated.
Dans cette chambre, composée de deux éléments hémi-tronconiques(26) s'articulant coaxialement (27 ) , le flux accéléré tangentiellement , se répartit, sans plateau, redans et vantaux, sur l 'ensemble des aubes de turbine.In this chamber, composed of two semi-frustoconical elements (26) articulating coaxially (27), the tangentially accelerated flow is distributed, without plate, steps and leaves, over all of the turbine blades.
Les deux éléments tronconiques constituent en fait un variateur d'admission accroissant ou limitant le débit par une modification de
l'angle d'admission du vent.The two frustoconical elements in fact constitute an intake variator increasing or limiting the flow rate by a modification of wind intake angle.
Cette variation s 'obtient par le truchement d'un dispositif aérostabilisateur omnifonctionnel(28)assujetti aux dits éléments hémi-tronco niques. Ce dispositif aérostabilisateur, (schéma,Fig.13) , comporte une dérive à deux battants asymétriques (29 et 30 ) ,coaxialeaent articulés et juxtaposés, l 'un contre l 'autre par vent nul. L 'asymétrie des deux battants de dérive stabilise dans la fil du vent la chambre d'aérovor tex, du fait qu'ils sont inégalement exposés à la pression dynamique SV2/2, engendrant ainsi un anticouple s'opposant au couple qui s 'exer ce dans la dite chambre.This variation is obtained by means of an omnifunctional aerostabilizing device (28) subject to said hemi-frusto-conical elements. This aerostabilizing device, (diagram, Fig.13), comprises a fin with two asymmetrical leaves (29 and 30), coaxial articulated and juxtaposed, one against the other by zero wind. The asymmetry of the two leaves drift stabilizes in the wind over the bed aérovor tex, because they are unevenly exposed to the dynamic pressure SV 2/2, thereby generating an anti-torque opposing the torque that s' exercise this in the said room.
Par ailleurs, ces deux battants de dérive se déploient sur un arc de 120° lorsque le vent s'exerce selon les vues schématiques , (Fig.14 et Fig.15) . Cette action se fait par l 'intermédiaire d'un bouclier frontal (31 ) solidaire des deux battants de dérive. Ce bouclier est cons titué par deux bras (32) qui prolongent chaque battant de dérive au delà de l 'articulation (27) . Ces deux bras sont respectivement prolongés par un volet articulé (33) . liais dès que le vent exerce une poussée frontale, ces deux volets , accompagnant les deux bras du bouclier, se déploient en masquant partiellement la dérive localisée en arrière de l 'axe d'articulation, en provoquant simultanément le déplacement des battants sur un arc de 120º . Ce déploiement modifie ainsi l 'angle d 'admission du vent dans la chambre d'aérovortex.In addition, these two drift wings deploy on an arc of 120 ° when the wind is exerted according to the schematic views, (Fig.14 and Fig.15). This action is carried out by means of a front shield (31) integral with the two wing wings. This shield is constituted by two arms (32) which extend each wing wing beyond the joint (27). These two arms are respectively extended by an articulated flap (33). linked as soon as the wind exerts a frontal thrust, these two flaps, accompanying the two arms of the shield, are deployed by partially masking the drift located behind the axis of articulation, simultaneously causing the movement of the leaves on an arc of 120º. This deployment thus modifies the angle of admission of the wind into the aerovortex chamber.
Dès lors , lorsque le vent dépasse un seuil prédéterminé en fonction d'un site, le bouclier, étant buté par le propre déploiement des deux battants , se replie à son tour, en démasquant ainsi une plus grande surface des dits battants.Therefore, when the wind exceeds a predetermined threshold depending on a site, the shield, being abutted by the own deployment of the two leaves, folds in turn, thus unmasking a larger area of the said leaves.
La longueur "L" du bras de levier, liée à la pression "P" exercée sur la surface des deux battants, excédant la longueur "l" du bras de levier des volets du bouclier, il s'ensuit, la pression "P" étant uniformément répartie , une force prépondérante qui repousse les extrémités des deux battants en fermant l 'angle d'admission du vent de 120° à 60° .The length "L" of the lever arm, linked to the pressure "P" exerted on the surface of the two leaves, exceeding the length "l" of the lever arm of the shield flaps, it follows, the pressure "P" being uniformly distributed, a preponderant force which pushes the ends of the two leaves by closing the angle of admission of the wind from 120 ° to 60 °.
Par contre, lorsque le vent faiblit la résilience des ressorts dépasse la pression exercé par le vent sur les volets du bouclier, ces derniers se déploient en couvrant et masquant une partie supplémentaire de la surface des deux battants qui reprennent aussitôt leur ouverture de 120° .
Par conséquent, l 'angle d' ouverture peut passer de 0° à 120° ou vice versa par le simple jeu de battants de dérive, d'un bouclier et de ressorts de rappel.On the other hand, when the wind weakens the resilience of the springs exceeds the pressure exerted by the wind on the shield flaps, the latter deploy by covering and masking an additional part of the surface of the two leaves which immediately resume their opening by 120 °. Consequently, the opening angle can be reduced from 0 ° to 120 ° or vice versa by the simple set of fins, a shield and return springs.
C 'est ainsi , que les très fortes rafales de vent, généralement des tructrices, sont domestiquées et transformées en énergie utilisable. Par analogie, le présent stato-éolien joue en quelque sorte le rôle d'un barrage hydraulique qui domestique un torrent impétueux pour en redistribuer ensuite l 'eau d'une hauteur convenable aux aubes des turbines hydrauliques. Cependant, l 'analogie se limite au domaine de la régulation, car le champ d'application du présent stato-éolien s'étend sur de nombreux créneaux de l 'activité humaine.This is how very strong gusts of wind, generally tructresses, are domesticated and transformed into usable energy. By analogy, this stato-wind plays in a way the role of a hydraulic dam which domesticates an impetuous torrent to then redistribute the water of a height suitable for the blades of the hydraulic turbines. However, the analogy is limited to the field of regulation, since the field of application of this stato-wind turbine extends over many niches of human activity.
Ainsi , en version simplifiée de petite échelle, en complément de batteries d'accus auto-rechargeables, il peut alimenter les refuges isolés, les auto-caravanes, les cruisers, les voiliers, les phares, les balises aériennes et maritimes, les bateaux de toute nature et participer aux télécommunications de détresse et obtenir la survie en mer par l 'eau douce en cas de naufrage.Thus, in a simplified small-scale version, in addition to self-recharging batteries, it can supply isolated shelters, motorhomes, cruisers, sailboats, lighthouses, aerial and maritime beacons, all kinds and participate in distress telecommunications and obtain survival at sea by fresh water in the event of sinking.
En version élaborée de toute dimension, il peut broyer tout matériau, épurer et dissocier l 'eau de mer ou de rivière, pomper l 'eau pour tous les besoins , thermopompes comprises, réhausser l 'eau des réservoirs , ou des châteaux d'eau, constituer une toiture énergétique de logements d'usines, d'ateliers ou de grandes surfaces commerciales et participer à l ' élaboration d'un carburant de synthèse. Plusieurs modules superposés peuvent alimenter des groupements de maisons individuelles ou collectives isolés.In an elaborate version of any size, it can grind any material, purify and dissociate sea or river water, pump water for all needs, including heat pumps, raise water in reservoirs, or water towers , build an energy roof for factory housing, workshops or large commercial areas and participate in the development of synthetic fuel. Several superimposed modules can supply groups of isolated individual or collective houses.
Enfin, ce stato-éolien se substitue à une multitude de servitudes universelles ou l ' économie d' énergie l 'exige.
Finally, this stato-wind turbine replaces a multitude of universal easements where energy saving requires it.
