<p>The invention relates to aerohydrodynamics and can be used in mechanical engineering for designing housings, in the textile industry for manufacturing sports clothing, in the building of pipelines for decreasing liquid or gas friction, and also in other areas of industry. A decrease in the hydrodynamic resistance of a medium is achieved. A streamlined surface (1) contains protruding elements in the form of teeth (2) that are pyramidal or conical in shape, and the tops of all of the teeth (2) are bent to one side.</p> |
