En la figura 1 se muestra un aerogenerador de eje horizontal, constituido de acuerdo con la invención, el cual está compuesto por tres palas (1) radiales que van montadas Figure 1 shows a horizontal axis wind turbine, constituted according to the invention, which is composed of three radial blades (1) that are mounted
30 sobre un eje central horizontal (2) que queda soportado por una columna o estructura vertical (3). 30 on a horizontal central axis (2) that is supported by a column or vertical structure (3).
Las palas (1) son de estructura laminar, constituidas a partir de una plancha de material resistente, de naturaleza metálica o a base de resina reforzada con fibras, etc. The blades (1) are of laminar structure, constituted from a sheet of resistant material, of a metallic nature or based on fiber reinforced resin, etc.
Las piezas laminares a partir de las que se conforman las palas (1) serán de contorno 35 poligonal. En la figura 3 se muestra el desarrollo (4) de una de las palas que conforma en aerogenerador de la figura 1 y que está constituido por una zona (5) de contorno triangular recto que se prolonga, a partir de uno de los catetos (6), en este caso del cateto mayor, en una franja rectangular (7) que discurre a todo lo largo de dicho cateto (6). The laminar pieces from which the blades (1) are formed will be polygonal in contour. Figure 3 shows the development (4) of one of the blades that forms in a wind turbine of Figure 1 and that is constituted by a zone (5) of straight triangular contour that extends, from one of the legs ( 6), in this case of the larger leg, in a rectangular strip (7) that runs along the entire leg (6).
En la figura 2 se muestra en perspectiva una de las palas (1) obtenidas a partir de la pieza laminar (4) de la figura 3. Para ello la pieza laminar (4) se curva y los vértices (8 y 9) quedan separados y atravesados por el eje de giro (2) del aerogenerador, conformando entre dichos vértices (8 y 9) un contorno curvo abierto (11) que corresponde al cateto menor (12) del desarrollo de la figura 3 más el lado transversal In figure 2 one of the blades (1) obtained from the sheet piece (4) of figure 3 is shown in perspective. For this the sheet piece (4) is curved and the vertices (8 and 9) are separated and crossed by the axis of rotation (2) of the wind turbine, forming between said vertices (8 and 9) an open curved contour (11) corresponding to the smaller leg (12) of the development of Figure 3 plus the transverse side

- de la franja rectangular (7) unida al cateto mayor. A partir de este contorno abierto of the rectangular strip (7) attached to the main leg. From this open contour
- (11)(eleven)
- la pala presenta una sección oblicua que reduce progresivamente el dicho contorno y que está definida por bordes (14 y 15) que se corresponden con el borde The blade has an oblique section that progressively reduces said contour and is defined by edges (14 and 15) that correspond to the edge
- (16)(16)
- del desarrollo (4) de la figura 3 y con el borde longitudinal libre (17) de la zona rectangular (7), disminuyendo al mismo tiempo la anchura de la pala hasta alcanzar su extremo libre (18) que se corresponde con el borde transversal libre (19) de la zona rectangular (7). of the development (4) of Figure 3 and with the free longitudinal edge (17) of the rectangular area (7), while reducing the width of the blade until it reaches its free end (18) corresponding to the transverse edge free (19) of the rectangular area (7).
El contorno curvo abierto de las palas si se realiza de izquierda a derecha del observador, el giro del aerogenerador se producirá en el sentido de las agujas del reloj, e inversamente será su giro si dicho contorno abierto se realiza de derecha a izquierda. The open curved contour of the blades if performed from left to right of the observer, the wind turbine will turn clockwise, and vice versa will be its rotation if said open contour is made from right to left.
Las palas conformadas de la figura (2), según se muestra en la figura 4, van fijadas mediante una placa central (20) que queda atravesada por el eje horizontal de giro (2) del aerogenerador. The shaped blades of figure (2), as shown in figure 4, are fixed by a central plate (20) that is crossed by the horizontal axis of rotation (2) of the wind turbine.
Con la constitución descrita, cada pala recibe la acción del viento según la dirección F1 de las figuras 1 y 2, que actúa sobre la zona más abierta de las palas, siendo conducido por las propias palas para salir de las mismas según la dirección F2 que incide en la zona más cerrada de la pala siguiente, según se muestra en la figura 1. With the constitution described, each blade receives the action of the wind according to the F1 direction of figures 1 and 2, which acts on the most open area of the blades, being driven by the blades themselves to exit them according to the direction F2 that it affects the most closed area of the next blade, as shown in figure 1.
De este modo el aerogenerador de la invención consigue el máximo aprovechamiento del viento, por la acción directa del mismo sobre las palas, según la dirección F1, y por la acción de la corriente F2 que cada pala provoca sobre la pala siguiente. In this way, the wind turbine of the invention achieves maximum use of the wind, by its direct action on the blades, according to the F1 direction, and by the action of the current F2 that each blade causes on the next blade.
En el ejemplo descrito el aerogenerador está constituido por tres palas, pero también podría formarse por sólo dos palas, según los desarrollos (4) de la figura 5, e incluso por 4 palas, según los desarrollos (4) de la figura 6, incluso un mayor número, estando en todos los casos las palas unidas a una placa central (20) que se fija al eje horizontal de giro (2). In the example described, the wind turbine consists of three blades, but it could also be formed by only two blades, according to the developments (4) of figure 5, and even 4 blades, according to the developments (4) of figure 6, including a greater number, being in all cases the blades attached to a central plate (20) that is fixed to the horizontal axis of rotation (2).
Todas las palas dirigirán el viento F1 que actúa sobre las mismas hacia la zona interior de las mismas, configuradas a modo de senos caudales o semicilindros colectores, donde el viento actuará con su máximo efecto para provocar el giro del aerogenerador. All the blades will direct the F1 wind that acts on them towards the inner area of the same, configured as flow breasts or half-cylinder collectors, where the wind will act with its maximum effect to cause the wind turbine to turn.
