Abstract

The surface structure has multiple recesses (1), troughs and/or craters, where a surface of an outer shell of a vehicle e.g. aeroplane, a rocket, and a missile, is structured completely or partially with the multiple recesses, troughs and/or craters. The recesses, troughs and/or craters are arranged closely together, where the recesses are curved or flat. The trough and/or craters have edges (2) that are designed in a square-edged manner. The troughs are designable in a round, oval and multi-angular such as triangular and quadrangular.
