DESCRIPCION DE LA INVENCION. i transform the rotational displacement of the blades into electrical energy. There are no known wind turbines in the state of the art in which the blades are joined together by a kite-like element. DESCRIPTION OF THE INVENTION
La presente invención propone el desarrollo de un nuevo generador eólico que comprende un mástil (6) en cuya parte superior se dispone un cabezal (11) en el se encuentra el eje central hueco en forma de cono (2), donde van alojados los mecanismos de rotación de las aspas, desde - 45° a +45° para poder captar mas o menos viento y optimizar la rotación del grupo. Este mecanismo tiene varias soluciones que se pueden aplicar, proponiendo la que esta formada por un hidráulico con doble brazo y montado sobre un amortiguador neumático, (3) cada brazo acciona 2 aspas y dicho amortiguador neumático permite cierta tolerancia en caso de vientos racheados.  The present invention proposes the development of a new wind generator comprising a mast (6) in whose upper part a head (11) is arranged in which the hollow cone-shaped central axis (2) is located, where the mechanisms are housed of rotation of the blades, from - 45 ° to + 45 ° to be able to capture more or less wind and optimize the rotation of the group. This mechanism has several solutions that can be applied, proposing that which is formed by a double-arm hydraulic and mounted on a pneumatic shock absorber, (3) each arm drives 2 blades and said pneumatic shock absorber allows some tolerance in case of gusty winds.
Los ejes de las aspas están en la parte delantera del eje o cono hueco y los mecanismos en la parte trasera para posibilitar de esa manera el mantenimiento y la reparación. Consta de cuatro aspas (4) con estructura similar a las utilizadas por los helicópteros; planas en toda su longitud, es decir, a diferencia de las hélices utilizadas normalmente por los molinos convencionales, y en su sección trasversal tienen forma de ojo alargado con una zona mas gruesa en su parte anterior y una mas fina en su parte posterior. Unos brazos articulados (5) que mediante rotulas (10) en la parte trasera de la cometa o borde de fuga y unos ejes pivotantes en la parte delantera de la cometa o borde de ataque, todo ello situado en el extremo de las aspas para sostener las cometas y que les dan la posibilidad de cazar mas o menos viento según la orientación que tengan, las condiciones de viento y la optimización de la computadora del generador eléctrico. Las cometas (1) configuradas con un diseño específico principalmente por ofrecer un borde de ataque curvo (8) y un borde de fuga recto (9), con la finalidad de poder aprovechar todo el viento posible sin llegar a tocar el mástil que soporta el conjunto en la rotación. Las cometas (1) así como el conjunto de la invención propuesta será preferentemente construida en los siguientes materiales: fibra de vidrio, carbono, maderas de balsa, keblar, epoxi, poliuretanos y espumas de relleno. También seria posible usar una estructura multitubular a modo de ala hueca con algún recubrimiento de materiales, tipo fibras o plásticos etc.. como solución para las aspas y las cometas. Por las características de los elementos anteriormente citados y la estructura que se propone del propio aerogenerador el conjunto de las partes a montar pueden reducirse en un 1/3 frente a los modelos actualmente utilizados, pero teniendo la misma superficie alar o en su envergadura y en consecuencia la misma capacidad de potencia, de esto se deduce que a un tamaño igual obtendremos una potencia un 60% superior al diseño de 3 hélices convencional. The axes of the blades are in the front of the shaft or hollow cone and the mechanisms in the rear to enable maintenance and repair. It consists of four blades (4) with similar structure to those used by helicopters; flat in its entire length, that is, unlike the propellers normally used by conventional mills, and in its cross section they have an elongated eye shape with a thicker area in its anterior part and a thinner one in its posterior part. Articulated arms (5) that by means of markers (10) on the back of the kite or trailing edge and pivoting axes on the front of the kite or leading edge, all located at the end of the blades to hold the kites and that give them the possibility of hunting more or less wind according to the orientation they have, the wind conditions and the optimization of the computer of the electric generator. The kites (1) configured with a specific design mainly for offering a curved leading edge (8) and a straight trailing edge (9), in order to take advantage of all the possible wind without touching the mast that supports the set in rotation. The kites (1) as well as the set of the proposed invention will preferably be constructed in the following materials: fiberglass, carbon, balsa wood, keblar, epoxy, polyurethanes and filler foams. It would also be possible to use a multitubular structure as a hollow wing with some coating of materials, fiber or plastic type etc. as a solution for the blades and kites. Due to the characteristics of the aforementioned elements and the proposed structure of the wind turbine itself, the set of parts to be assembled can be reduced by 1/3 compared to the models currently used, but having the same alar surface or its size and consequently the same power capacity, from this it follows that at an equal size we will obtain a power 60% higher than the conventional 3-helices design.
La ligereza del conjunto se debe a que las partes son mucho mas pequeñas y a la capacidad de "volar" de las cometas que una vez iniciada su rotación generarían una auto-sustentación del conjunto, gracias a su diseño novedoso ira incrementando la velocidad de giro de forma gradual, consiguiéndose mas revoluciones y menor peso. The lightness of the set is due to the fact that the parts are much smaller and the ability to "fly" from the kites that once started their rotation would generate a self-sustaining of the set, thanks to its innovative design will increase the speed of rotation of Gradually, getting more revolutions and less weight.
La flexibilidad del material de la cometa permite que los laterales de la misma en el borde de fuga cedan a la tensión de las rotulas accionadas por las aspas, de esta forma también la cometa adopta una forma un tanto deformada en dichos extremos del borde de fuga que ayudan a la rotación del grupo. Todo esto ha de ser controlado por el ordenador apoyado en un software específico que será el encargado de gobernar en función de los valores que previamente se le indiquen. El borde de ataque del aspa es mucho más fino que las hélices conocidas con lo que la resistencia al giro se ve reducida de manera importante. The flexibility of the kite's material allows the sides of the kite on the trailing edge to give way to the tension of the pads driven by the blades, in this way also the kite adopts a somewhat deformed shape at said ends of the trailing edge that help the rotation of the group. All this must be controlled by the computer supported by a specific software that will be responsible for governing based on the values previously indicated. The leading edge of the blade is much thinner than the known propellers, so the resistance to rotation is significantly reduced.
El sistema de giro de las aspas y las cometas montado sobre un sistema hidráulico y neumático a modo se silenblock elimina vibraciones y permite a aspas y cometas abatirse en condiciones de fuertes rachas de viento con lo que se consigue que no sufra el grupo y elimina la posibilidad de roturas alargando la vida útil del conjunto del aerogenerador.  The system of rotation of the blades and kites mounted on a hydraulic and pneumatic system as a sileblock eliminates vibrations and allows blades and kites to fall down in conditions of strong gusts of wind so that the group does not suffer and eliminates the possibility of breakages extending the useful life of the wind turbine assembly.
Los costes de fabricación y trasporte de las piezas de la invención aquí propuesta son menores en relación a los aerogeneradores conocidos ya que hay una reducción de los elementos y piezas que se utilizan que en el caso de las hélices sería de de aproximadamente 1/3. En consecuencia también el montaje requiere de menor esfuerzo y de grúas más pequeñas. Un impacto visual menor, abaratando los costes propios del proceso de producción de las partes del aerogenerador así como el montaje y transporte. Es más silencioso pues no hay ningún final de hélice que corte el viento. La capacidad de abatir totalmente el conjunto desde -45° a 0o y +45° (Menos 45 Grados, Cero Grados y Mas 45 Grados) nos permite captar todo el viento disponible, también dejar a cero la capacidad de captación de viento en caso de tormenta o huracán y la posibilidad de frenar el conjunto en posición de contra-rotación para detenerlo en caso de rotura o emergencia, adoptando las cometas una forma determinada con baja potencia y máxima potencia. The manufacturing and transportation costs of the parts of the invention proposed here are lower in relation to the known wind turbines since there is a reduction of the elements and parts that are used that in the case of the propellers would be approximately 1/3. Consequently, the assembly also requires less effort and smaller cranes. A lower visual impact, lowering the costs of the production process of the parts of the wind turbine as well as the assembly and transport. It is quieter because there is no end of propeller that cuts the wind. The ability to fully knock down the set from -45 ° to 0 or + 45 ° (minus 45 Degrees, Zero Degrees and More 45 Degrees) allows us to capture all available wind, also zero wind capacity in case of storm or hurricane and the possibility of stopping the assembly in counter-rotation position to stop it in case of breakage or emergency, adopting the kites in a certain way with low power and maximum power.
Hemos eliminado el problema de la perdida de sustentación a bajas revoluciones pues el aspa tiene un borde de ataque muy fino y la cometa ayuda en la rotación del grupo.
