Description
Elemento impulsor aerodinámico.Aerodynamic drive element.
La presente invención, tal y como se expresa en el enunciado de esta memoria descriptiva, se refiere a un elemento impulsor aerodinámico cuya finalidad consiste en proporcionar un recubrimiento para una superficie de fricción con un fluido tal como aire, agua u otro al objeto de reducir esa fricción y facilitar el avance por el fluido del objeto al que pertenece esa superficie, para lo cual la invención proporciona un elemento modular que puede aplicarse repetitivamente sobre superficies sujetas a elevados grados de fricción aerodinámica, tales como las superficies de vehículos aéreos, terrestres o acuáticos, para minimizar la resistencia al avance que determina el fluido y para añadir unas zonas de empuje favorables al sentido de avance del objeto que incorpora elemento impulsor de la invención.The present invention, as expressed in the statement of this specification refers to an element aerodynamic impeller whose purpose is to provide a coating for a friction surface with such a fluid as air, water or other in order to reduce that friction and facilitate the advance by the fluid of the object to which that belongs surface, for which the invention provides an element modular that can be applied repeatedly on surfaces subject to high degrees of aerodynamic friction, such as surfaces of air, land or water vehicles, for minimize the resistance to the advance that determines the fluid and for add favorable thrust zones to the direction of advance of the object incorporating driving element of the invention.
Actualmente, se investiga el modo de minimizar la resistencia que determinadas superficies presentan al roce o fricción con determinados fluidos. Para ello se han desarrollado revestimientos o pinturas especiales con aplicación especial a cascos de embarcaciones de competición, como las empleadas en pruebas de vela o velocidad. También se aplican en aeronaves en las que se quiere obtener un elevado rendimiento por minimización de la fricción del aire. En el estado actual de la técnica se dan inconvenientes relativos a que hasta ahora no se ha conseguido una superficie que no solo minimice la fricción y por lo tanto la resistencia al avance sino que además genere un efecto de empuje tal como el que hacen determinados dispositivos aerodinámicos que se colocan en camiones o vehículos de gran tamaño para producir efectos de auto-avance y reducir el consumo de combustible, como por ejemplo los mostrados en la patente española con número de publicación 2.285.889 ó en la patente estadounidense 4.316.630.Currently, how to minimize is investigated the resistance that certain surfaces present to rubbing or friction with certain fluids. For this they have developed special coatings or paints with special application to racing boat hulls, such as those used in sailing or speed tests. They also apply to aircraft in that you want to obtain high performance by minimizing air friction In the current state of the art they are given inconveniences related to the fact that until now a surface that not only minimizes friction and therefore the feed resistance but also generate a thrust effect such as what certain aerodynamic devices do that they are placed in trucks or large vehicles to produce self-advance effects and reduce the consumption of fuel, such as those shown in the Spanish patent with publication number 2,285,889 or in US Pat. 4,316,630.
No conocemos en el estado actual de la técnica ningún elemento impulsor aerodinámico que facilite un recubrimiento en superficies de fricción con un fluido donde cada elemento presente una forma aproximada de rombo con una zona frontal convexa y una zona posterior cóncava, tal y como lo hace el elemento de la presente invención.We do not know in the current state of the art no aerodynamic drive element that facilitates a coating on friction surfaces with a fluid where each element present an approximate shape of rhombus with an area convex front and a concave rear area, just as the element of the present invention.
Para lograr los objetivos y evitar los inconvenientes indicados en anteriores apartados, la invención consiste en un elemento impulsor aerodinámico previsto para ser colocado sobre una superficie de fricción con un fluido tal como aire, agua u otro, al objeto de reducir esa fricción y facilitar el avance por el fluido del objeto al que pertenece esa superficie.To achieve the objectives and avoid drawbacks indicated in previous sections, the invention consists of an aerodynamic drive element intended to be placed on a friction surface with a fluid such as air, water or other, in order to reduce this friction and facilitate advance through the fluid of the object to which that belongs surface.
Novedosamente, según la invención, cada elemento impulsor presenta una zona frontal de superficie exterior convexa y contorno aproximadamente triangular que conecta a través de una zona de depresión con una zona posterior de superficie exterior cóncava y contorno aproximadamente triangular, de manera que el contorno total del elemento tiene una forma aproximada de rombo y de manera que la zona de depresión permite generar una turbulencia del fluido, en el avance del elemento, que proporciona una fuerza de empuje favorable al referido avance del objeto.Novelly, according to the invention, each element impeller has a convex outer surface frontal area and approximately triangular contour that connects through a depression zone with a posterior surface area concave and approximately triangular contour, so that the total contour of the element has an approximate shape of rhombus and so that the depression zone allows to generate a turbulence of the fluid, in the advance of the element, which provides a force of favorable thrust to the referred advance of the object.
Según la realización preferente de la invención, la referida forma aproximada de rombo presenta los bordes correspondientes a la zona frontal curvo-convexos, en tanto que los bordes correspondientes a la zona posterior son curvo-cóncavos.According to the preferred embodiment of the invention, the approximate rhombus shape presents the edges corresponding to the curved-convex frontal zone, while the edges corresponding to the posterior area are curved-concave.
El elemento impulsor de la invención se puede incorporar junto con otros iguales a modo de recubrimiento de la superficie de fricción y con distribución de tresbolillo, de manera que la zona frontal de cada elemento queda ajustada entre dos zonas posteriores de otros dos elementos, mientras que la zona posterior de cada elemento queda ajustada entre dos zonas frontales de otros dos elementos.The driving element of the invention can be incorporate together with other equals by way of covering the friction surface and with distribution of tresbolillo, so that the front area of each element is adjusted between two zones back of two other elements, while the back area of each element is adjusted between two frontal areas of others two elements

Seguidamente se realiza una descripción de un ejemplo de la invención haciendo referencia a la numeración adoptada en las figuras.Following is a description of a example of the invention with reference to numbering Adopted in the figures.
Así, cada elemento impulsor 1 del presente ejemplo dispone de una zona frontal 6 que tiene un perfil ascendente, un contorno aproximadamente triangular y una superficie exterior convexa, tal y como se aprecia en las figuras 1 y 2.Thus, each driving element 1 of the present example has a front area 6 that has a profile ascending, an approximately triangular contour and a surface convex exterior, as seen in figures 1 and 2.
Esa zona frontal 6 finaliza en una zona de depresión 3 o zona de turbulencia donde el fluido en el que se aplica el elemento impulsor 1 genera una fuerza de empuje 4 en sentido favorable al avance del elemento 1 por el fluido, tal y como se aprecia en la figura 2.That frontal zone 6 ends in an area of depression 3 or zone of turbulence where the fluid in which it applied the driving element 1 generates a pushing force 4 in sense favorable to the advancement of element 1 through the fluid, such and as seen in figure 2.
La zona de depresión 3 conecta a su vez con una zona posterior 2 que permite lanzar la corriente de fluido hacia el próximo elemento impulsor 1.The depression zone 3 connects in turn with a rear zone 2 that allows the flow of fluid to be released towards the next driving element 1.
La distribución de los elementos impulsores 1 por la superficie de fricción 5 con el fluido es una distribución al tresbolillo, tal y como se refleja en la figura 1, de manera que las zonas posteriores 2 quedan ajustadas con las zonas frontales 6 de otros elementos 1.The distribution of the driving elements 1 by the friction surface 5 with the fluid is a distribution to the tresbolillo, as reflected in figure 1, so that the back zones 2 are adjusted with the front zones 6 of other elements 1.
En el presente ejemplo, en la forma aproximada de rombo que presenta cada elemento impulsor 1, los bordes correspondientes a la zona frontal 6 son curvo-convexos, mientras que los bordes correspondientes a la zona posterior 2 son curvo-cóncavos, tal y como se aprecia en la figura 1.In the present example, in the approximate form of rhombus presenting each driving element 1, the edges corresponding to the frontal zone 6 are curved-convex while the edges corresponding to the back zone 2 are curved-concave, as shown in the figure one.
El tamaño de los elementos impulsores 1 puede variar en función del tipo de superficie o de embarcación, nave o vehículo que se desea recubrir, siendo posible revestir solamente determinadas partes sometidas a mayor fricción en dicho vehículo.The size of the driving elements 1 can vary depending on the type of surface or vessel, ship or vehicle to be covered, being possible to cover only certain parts subject to greater friction in said vehicle.
Por otra parte, los materiales con los que se puede construir el elemento impulsor del presente ejemplo pueden ser materiales convencionales tales como plásticos, metales u otros. Asimismo, los adhesivos para la conexión de los elementos 1 a la superficie de fricción 5 también pueden ser pegamentos o adhesivos convencionales. Otra posibilidad de realización, consiste en que la propia superficie 5 presente una cara con relieves análogos a los que determinarían una pluralidad de elementos 1 distribuidos al tresbolillo; sin descartarse otro tipo de realizaciones.On the other hand, the materials with which can build the driving element of the present example can be conventional materials such as plastics, metals or others. Also, the adhesives for the connection of the elements 1 to the friction surface 5 can also be glues or conventional adhesives Another possibility of realization, consists in which the surface 5 itself has a face with reliefs analogous to those who would determine a plurality of elements 1 distributed to tresbolillo; without ruling out another type of realizations
