Description
Vela para embarcaciones.Sail for boats.
La presente invención se refiere a una vela para embarcaciones.The present invention relates to a candle for boats
El objeto de la invención es conseguir mejorar sustancialmente el rendimiento en el efecto del viento al incidir sobre la vela.The object of the invention is to improve substantially the effect on the effect of the wind upon impact On the candle
La invención se sitúa pues en el sector técnico relativo a la dinámica de fluidos, y mas concretamente en lo relativo a la navegación a vela.The invention is therefore located in the technical sector relative to fluid dynamics, and more specifically as regards relative to sailing.
En un barco de vela, el viento al encontrarse con la vela ejerce una fuerza y un par sobre el barco. Para compensar el citado par se utiliza el propio peso del barco y para compensar la fuerza principalmente se utiliza la quilla que, al avanzar sobre el agua, ejerce una fuerza en sentido contrario al de la vela.In a sailboat, the wind when meeting with the sail exerts a force and a pair on the ship. For to compensate the mentioned pair the own weight of the boat is used and for compensate the force mainly the keel is used which, when advancing on water, exerts a force in the opposite direction of sailing.
Las velas tradicionales tienen en general una forma cercana a la triangular y están fabricadas en paño o material sintético y se sujetan al barco mediante cuerdas fijadas en el palo mayor y en la botavara.Traditional candles generally have a close to the triangular shape and are made of cloth or material synthetic and are attached to the boat by ropes fixed on the stick major and in the boom.
La vela mayor va unida al casco del barco.The mainsail is attached to the hull of the ship.
Así pues, la vela frente al flujo del viento,
situada en un ángulo pequeño, produce una influencia sobre dicho
flujo que genera en la parte de sotavento de la vela una
aceleración del flujo, y el la parte de barlovento una
ralentización. Debido a este efecto se tiene una presión menor en la
parte de sotavento y una presión mayor en la parte de barlovento,
lo que hará hincharse la vela, lo que provocará una fuerza
resultante que es la que se utiliza para mover el
barco.Thus, the sail against the flow of the wind, located at a small angle, produces an influence on said flow that generates an acceleration of the flow in the leeward part of the sail, and the windward part slows down. Due to this effect there is a lower pressure in the leeward part and a higher pressure in the windward part, which will cause the candle to swell, which will cause a resulting force that is used to move the
ship.
Así pues, la geometría de las velas no es la geometría óptima para aprovechar la fuerza del viento debido a su forma exenta de grosor.So, the geometry of the candles is not the Optimal geometry to take advantage of wind force due to its thickness free form.
Esto repercute negativamente en el rendimiento del esfuerzo generado por el viento.This has a negative impact on performance. of the effort generated by the wind.
La vela que se preconiza resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, consiguiendo una sustancial mejora en el rendimiento.The candle that is recommended resolves in a way the problem described above is fully satisfactory, getting a substantial improvement in performance.
De forma mas concreta la vela de la invención es una vela doble, de manera que una vez que se caza el viento las dos velas comienzan a hincharse y provocan la auto-orientación del conjunto para adquirir una forma alar.More specifically, the candle of the invention is a double sail, so that once the wind is hunted the two candles begin to swell and cause the self-orientation of the set to acquire a alar shape
De esta manera se consigue que las dos velas trabajen cada una de ellas como una vela convencional, en su conjunto con un rendimiento y forma muy similar al de un ala.This way you get the two candles work each of them as a conventional candle, in your together with a performance and shape very similar to that of a wing.
Esta solución técnica tiene además la particularidad de ser capaz de orientarse de forma autónoma utilizando mecanismos sencillos y robustos.This technical solution also has the particularity of being able to orientate autonomously using simple and robust mechanisms.
Para complementar la descripción que se está realizando y con objeto de ayudar a una mejor comprensión de las características del invento, de acuerdo con un ejemplo preferente de realización práctica del mismo, se acompaña como parte integrante de dicha descripción, un juego de dibujos en donde con carácter ilustrativo y no limitativo, se ha representado lo siguiente:To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:
La figura 1.- Muestra un detalle parcial en perspectiva y una sección transversal del mismo, correspondiente a una vela realizada de acuerdo con el objeto de la presente invención y sin la incidencia del aire.Figure 1.- Shows a partial detail in perspective and a cross section of it, corresponding to a candle made in accordance with the purpose of this invention and without the incidence of air.
La figura 2.- Muestra una representación similar a la figura 1, pero en la que la vela recibe la incidencia del aire con un ángulo pequeño con respecto a su eje.Figure 2.- Shows a similar representation to figure 1, but in which the candle receives the incidence of air with a small angle with respect to its axis.
La figura 3.- Muestra, según una representación similar a las figuras anteriores, la vela en su conjunto debidamente montada sobre el palo mayor y la botavara.Figure 3.- Shows, according to a representation similar to the previous figures, the candle as a whole duly mounted on the main pole and the boom.
La figura 4.- Muestra un detalle en planta de la forma inicial de los cables que colaboran con la vela.Figure 4.- Shows a detail in plan of the Initial form of the wires that collaborate with the candle.
La figura 5.- Muestra un detalle de la parte delantera del palo mayor, donde éste recibe a la vela doble.Figure 5.- Shows a detail of the part front of the main mast, where it receives the double sail.
La figura 6.- Muestra, finalmente, un detalle en planta de la membrana que participa también en la vela doble.Figure 6.- Shows, finally, a detail in Membrane plant that also participates in the double sail.
A la vista de las figuras referidas y en especial de las figuras 1 y 2, se observa como la vela doble (1) rodea a una estructura interna que posee un eje de pivotamiento principal (2) en la parte delantera, de manera que sobre este eje pivota una segunda estructura (3) con punta redondeada, que da forma al borde de ataque de la vela doble (1), de manera que cada una de las velas se engarza entre un eje de pivotamiento secundario (4), situado sobre la punta redondeada y la parte trasera y fija sobre la que se unen ambas velas formando un ángulo (5) determinado.In view of the referred figures and in special figures 1 and 2, it is observed as the double candle (1) surrounds an internal structure that has a pivot axis main (2) in the front, so that on this axis pivots a second structure (3) with rounded tip, which gives shape at the leading edge of the double sail (1), so that each one of the sails is hooked between a secondary pivot shaft (4), located on the rounded tip and the back and fixed on which both candles join at an angle (5) determined.
De acuerdo con esta estructuración y cuando sobre la vela doble incide un fluido (F) con un ángulo pequeño respecto a su eje, de la misma forma que actúan las velas tradicionales, las dos velas comienzan a hincharse y provocan la auto-orientación del conjunto, de manera que la estructura interna de punta redondeada (3) pivotará sobre el eje primario (2) un ángulo \alpha. Este giro dará a cada vela la longitud adecuada, mas corta la del lado (1') que recibe directamente el fluido y mas larga la del lado contrario. La vela en la que se recibe directamente el fluido pivotará sobre el eje secundario formando la parte inferior del perfil alar (intrados) y la del otro lado pivotará igualmente sobre el eje secundario formando la parte superior del perfil alar (extrados).According to this structuring and when a fluid (F) with a small angle hits the double sail with respect to its axis, in the same way that candles act traditional, the two candles begin to swell and cause the self-orientation of the set, so that the internal rounded tip structure (3) will pivot on the shaft primary (2) an angle α. This turn will give each candle the adequate length, shorter than the side (1 ') it receives directly the fluid and longer than the opposite side. The candle in the one that is received directly the fluid will pivot on the axis secondary forming the lower part of the alar profile (intrados) and the one on the other side will also pivot on the secondary axis forming the upper part of the alar profile (extracted).
La diferencia de presiones entre ambas caras de las velas las hará hincharse trabajando cada una igual que una vela tradicional, ya que se generan tres presiones diferentes, la vela que recibe directamente el fluido tendrá la mayor presión P1, la vela del otro lado tendrá la menor presión P3, y en el medio de ambas se genera una presión intermedia P3.The pressure difference between both sides of the candles will make them swell working each one like a candle traditional, since three different pressures are generated, the candle which directly receives the fluid will have the highest pressure P1, the candle on the other side will have the lowest pressure P3, and in the middle of both an intermediate pressure P3 is generated.
De acuerdo con esta funcionalidad, en las figuras 3 a 6 se ha representado la vela completa con sus accesorios, y así en la figura 3, donde dicha vela doble recibe el viento incidiendo sobre ella, vela formada por el material utilizado en las velas convencionales, dicha vela doble (1) posee un eje de pivotamiento principal (2) en la parte delantera, materializada en la práctica en el palo mayor, sobre este eje pivota una estructura con punta redondeada (3) que da forma al borde de ataque de la vela doble, las dos velas están reforzadas por sables (6) con una curvatura determinada, de manera que cada cable está fijado entre el eje secundario de pivotamiento (4) situado en la estructura con punta redondeada, estando dichos cables fijados entre sí en la parte trasera (5) de la vela. Un doble cable (7) en paralelo unirá el extremo libre de la botavara con la parte superior de la vela mayor, a fin de fijar la posición de la parte trasera de la vela doble.According to this functionality, in the figures 3 to 6 the complete candle with its accessories, and so in figure 3, where said double candle receives the wind hitting her, sail formed by the material used in conventional candles, said double candle (1) has a main pivot shaft (2) in the front, materialized in practice in the main suit, on this axis pivots a structure with rounded tip (3) that shapes the leading edge of the double sail, the two sails are reinforced by sabers (6) with a certain curvature, so that each cable is fixed between the secondary pivot shaft (4) located in the structure with rounded tip, said cables fixed to each other at the rear (5) of the candle. A double cable (7) in parallel will join the free end of the boom with the upper part of the mainsail, in order to fix the position from the back of the double candle.
De forma mas concreta el sable (6) debe tener una curvatura cóncava en el tercio delantero y no tener curvatura en el resto del cable, como se observa perfectamente en la figura 4 y las dos mitades del mismo van unidas en la parte posterior, con un ángulo pequeño que se mantendrá fijo, por lo que en el momento en el que no está incidiendo el viento se obtendrá un perfil similar a una pinza.More specifically, the saber (6) must have a concave curvature in the front third and have no curvature in the rest of the cable, as perfectly seen in figure 4 and the two halves of it are joined in the back, with a small angle that will remain fixed, so at the moment in which the wind is not affecting a profile will be obtained similar to a clamp.
En cualquier caso cabe señalar que no es imprescindible el uso de sables para permitir que funcione la vela doble, aunque sin su utilización los rendimientos resultan algo inferiores.In any case it should be noted that it is not it is essential to use sabers to allow the candle to work double, although without its use the yields are somewhat lower.
En la figura 5 se ha representado un detalle del eje de pivotamiento principal (2), materializado en el palo mayor, donde se aprecia con claridad la guía (8) que hace funciones de eje primario que hace las funciones de eje primario donde se inserta y pivota la estructura con punta redondeada (3).A detail of the main pivot shaft (2), materialized on the main pole, where you can clearly see the guide (8) that performs axis functions primary that functions as the primary axis where it is inserted and pivot the structure with rounded tip (3).
En el caso de que la vela doble se pueda arriar, la estructura de punta redondeada no podrá ser una forma asimilable a un tronco de cono sólido, tal como muestran las figuras 1 y 2, sino que deben existir varias estructuras de punta redondeada, independientes, que pueden subir y bajar por la guía, de tamaño decreciente, con una forma triangular y en su punta una argolla circular (9).In the event that the double candle can be lowered, the rounded tip structure may not be an assimilable form to a solid cone trunk, as shown in Figures 1 and 2, but there must be several rounded tip structures, independent, which can go up and down the guide, in size decreasing, with a triangular shape and at its tip a ring circular (9).
Para izar y arriar la vela se utiliza un cabo como en las velas tradicionales, de manera que la estructura de punta redondeada se deslizará por la guía en la parte delantera del palo mayor y como guía en la parte trasera de la vela se utilizará el doble cable (7) que se une el extremo de la botavara (10), con la parte superior de la vela mayor (1).To raise and lower the sail a rope is used as in traditional candles, so that the structure of rounded tip will slide along the guide in the front of the main stick and as a guide at the back of the candle will be used the double cable (7) that joins the end of the boom (10), with the upper part of the mainsail (1).
Sobre las argollas de la estructura de punta redondeada se situará el eje de pivotamiento secundario. Las argollas y los cables estarán unidos por un eje (11) que permite a los sables (6) pivotar en un ángulo para adquirir la forma adecuada.On the rings of the tip structure rounded the secondary pivot axis will be located. The rings and cables will be joined by an axis (11) that allows the sabers (6) pivot at an angle to acquire the shape adequate.
Para eliminar la circulación del aire por el interior de las dos velas (1-1') y por tanto reducir el rozamiento, se utiliza una membrana flexible (12), en la parte superior de la vela doble, permitiendo que la parte baja de la vela mantenga la presión adecuada en el interior de las dos velas (1-1').To eliminate air circulation through the inside of the two candles (1-1 ') and therefore reduce friction, a flexible membrane (12) is used, in the upper part of the double candle, allowing the lower part of the candle maintain adequate pressure inside the two candles (1-1 ').
Por último, la parte baja de las dos velas queda unida mediante cuerdas (13) que pasan por unas ruedecillas (14) situadas en la botavara (10) y que permiten a la parte baja de la vela reorientarse y darle a la vez la rigidez suficiente para evitar el flameo de las velas que se produciría en esta zona en caso de ir libres.Finally, the bottom of the two candles is joined by ropes (13) that pass through some casters (14) located in the boom (10) and that allow the lower part of the candle redirect and give it enough rigidity to avoid the candle flames that would occur in this area in Case of going free.
