Surfaces, sides, edges and fronts of bodies completely or partly covered with bulges alone or with bulges and teeth for reducing the resistance of gaseous and/or liquid substances

摘要

Conventional bodies are reduced by a large resistance of gaseous and/or liquid substances. The bodies, which are completely or partly covered with bulges or with bulges and teeth, reduce the resistance by the gaseous and/or liquid substances being accelerated to the outside by these bulges and teeth. Form, depth and spacing of the bulges as well as form, length, width, spacing and orientation of the teeth and which part of the body has to be covered with more or less rows of bulges alone or with bulges and teeth depends on the size, form and speed of the body.
