Structural Element For Reducing A Flow Resistance

Abstract

A structural element for attachment to an outer skin of a vehicle, in particular a transport vehicle, a passenger car, a rail vehicle, an aircraft and/or a watercraft, includes a main fin and a first and a second secondary fin. These secondary fins are arranged next to the main fin such that a first channel is formed between the first secondary fin and the main fin and a second channel is formed between the second secondary fin and the main fin. The first channel and the second channel each have a change in cross-section such that when a fluid flows through the first channel or the second channel, a change in the flow velocity of the fluid occurs. In this way, the flow behavior of a fluid around the vehicle can be influenced and the flow resistance acting on the vehicle can be effectively reduced.
