Definitions

  • the present invention refers to an aerodynamic driving element whose purpose is to provide a coating for a friction surface with a fluid such as air, water or other in order to reduce that friction and facilitate the advance by the fluid of the object to which that surface belongs, for which the invention provides a modular element that can be applied repetitively on surfaces subject to high degrees of aerodynamic friction, such as the surfaces of aerial, land vehicles or aquatic, to minimize the resistance to the advance that determines the fluid and to add some areas of thrust favorable to the direction of advance of the object that incorporates driving element of the invention.
  • the invention consists of an aerodynamic driving element intended to be placed on a friction surface with a fluid such as air, water or other, in order to reduce that friction and facilitate the advance through the fluid of the object to which that surface belongs.
  • each driving element has a convex outer surface frontal area and approximately triangular contour that connects through a depression zone with a concave outer surface area 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 thrust force favorable to the referred advance of the object.
  • said approximate rhombus shape has the edges corresponding to the curved-convex frontal zone, in so much so that the edges corresponding to the posterior area are curved-concave.
  • the driving element of the invention can be incorporated together with other equals as a coating of the friction surface and with a three-pin distribution, so that the front area of each element is adjusted between two rear zones of two other elements, while the rear area of each element is adjusted between two frontal areas of two other elements.
  • the aerodynamic driving element of the invention has relative advantages in that it reduces friction against a fluid on a surface that the driving element is placed, mainly due to the area of depression of the element that causes turbulence in the advance of the corresponding object through the fluid, facilitating this turbulence a favorable thrust to the advance of the object.
  • the invention has the advantages that it is simple to carry out and easy to apply on a wide variety of surfaces.
  • Figure 1. Represents a top plan view of an embodiment of the aerodynamic drive element of the present invention, showing a plurality of said elements placed on the treadmill on a friction surface with a fluid.
  • Figure 2. Represents a profile view according to the section indicated in the previous figure 1, showing the complete profile of one of the driving elements. DESCRIPTION OF AN EXAMPLE OF EMBODIMENT OF THE INVENTION Next, a description of an example of the invention is made with reference to the numbering adopted in the figures.
  • each driving element 1 of the present example has a front area 6 having an ascending profile, an approximately triangular contour and a convex outer surface, as seen in Figures 1 and 2.
  • That frontal zone 6 ends in an area of depression
  • the depression zone 3 connects in turn with a rear zone 2 which allows the flow of fluid to be released towards the next driving element 1.
  • the distribution of the driving elements 1 by the friction surface 5 with the fluid is a triplet distribution, as shown in Figure 1, so that the rear zones 2 are adjusted with the front zones 6 of other elements 1 .
  • each drive element 1 in the approximate rhombus shape of each drive element 1, the edges corresponding to the frontal zone 6 are curved-convex, while the edges corresponding to the posterior zone 2 are curved-concave, as appreciate in figure 1.
  • the size of the driving elements 1 may vary depending on the type of surface or vessel, ship or vehicle to be coated, it being possible to coat only certain parts subjected to greater friction in said vehicle.
  • the materials with which the driving element of the present example can be constructed can be conventional materials such as plastics, metals or others.
  • the adhesives for connecting the elements 1 to the friction surface 5 can also be conventional adhesives or adhesives. Another possibility of realization consists in the fact that the surface 5 itself has a face with similar reliefs to which a plurality of elements 1 distributed to the treadmill would be determined; without discarding other types of achievements.

Abstract

La présente invention concerne un élément moteur aérodynamique qui est placé sur une surface de frottement avec un fluide en vue de réduire ce frottement. Chaque élément (1) est composé d'une zone frontale convexe (6) qui présente un contour approximativement triangulaire et qui est reliée par l'intermédiaire d'une zone de dépression (3) à une zone postérieure concave (2) qui présente un contour approximativement triangulaire, le contour global se présentant approximativement sous forme de losange et permettant à la zone de dépression (3) de générer une turbulence du fluide lorsque l'élément (1) avance, ce qui fournit une force de poussée favorable à cette avance.
