Abstract

An aerodynamic surface comprises a plurality of grooves. The surface may be used in vehicles, bullets or turbines.

Description

The structure of the surface in the form of grooves adjacent to each other which have the shape of the part of the circle in the cross-section.
Technical Field
The structure of the surface in the form of grooves adjacent to each other which have the shape of the part of the circle in the cross-section applied for vehicles, bullets, turbines and other objects decreases fluid resistance during their relative motion, what makes it possible to increase their relative velocity between the object and the fluid or reduce their fuel consumption.
Background Art
Well-known in the use is the structure of the surface of the golf ball.
Disclosure
According to the invention, the chosen outer surfaces that oppose the relative motion of vehicles, bullets, turbines and other objects through a fluid (a liquid or gas) are in the form of grooves adjacent to each other. The grooves have the shape of the part of the circle or very close to a part of the circle in cross-section in the plane perpendicular to the surface and also parallel to the direction of relative motion. The structure reduces fluid resistance.
The structure of the surface can have different sizes and patterns of grooves, depending on the size and the shape of the surface of the object and depending on the relative speed between the object and the fluid, and depending on the environment in which the object moves.
The structure is applied in places where its application is possible and desirable.
Description of Drawings
The subject of the invention in example is shown on the illustration in which fig. 1 and fig. 2 presents the fragment of the surface 1 of the element 2 which moves in the direction of its relative motion 3, wherein the grooves have the shape of the part of the circle in cross-section in the plane perpendicular to the surface 1 and also parallel to the direction of relative motion 3.
Fig. 3, fig. 4 and fig. 5 show the edges of grooves. The edges of grooves can be sharp, round 6 or flat 7.
Industrial Applicability
The object of the invention can find the use at vehicles, bullets, turbines and other moving objects or their elements, or at stationary objects or their elements which needs reducing fluid resistance.
