<p>The invention relates to an aerodynamic thrust element which is positioned on a surface subject to friction with a fluid in order to reduce said friction. Each element (1) includes a front convex area (6) which has an approximately triangular profile and is connected via a depression area (3) to a rear concave area (2) also having an approximately triangular profile, the overall profile having an approximately rhombic shape. The aforementioned depression area (3) enables a turbulence to be generated in the fluid as the element (1) moves forward, which provides a thrust force that favours said forward movement.</p> |
