Abstract
A structural component for a vehicle has a surface with a riblet structure. The riblet structure includes a plurality of grooves, including a first groove having a first longitudinal section forming a first angle with a main longitudinal direction of the structural component. The first angle is larger than 0° and the main longitudinal direction corresponds to a flow direction of a fluid along the surface of the structural component.

A structural component for a vehicle, the structural component comprising:
- a surface;
- and
- a riblet structure comprising a plurality of grooves on the surface,
- wherein a first groove of the plurality of grooves has a straight longitudinal main section extending in a main longitudinal direction,
- wherein the first groove of the plurality of grooves also has a first longitudinal section forming a first angle with the main longitudinal direction of the structural component,
- wherein the first longitudinal section branches off the straight longitudinal main section at a branch and extends completely straight from said branch to an endpoint of the first groove, at which endpoint the first groove has no depth,
- wherein the first angle is larger than 0°, and
- wherein the main longitudinal direction extends in a flow direction of a fluid along the surface of the structural component.
