Riblet structure on a flow surface, method for producing a riblet structure on a flow surface and use of reinforcing elements in riblets for a flow area

摘要

A riblet structure (2) for a flow surface has a multiplicity of riblets (4) which consist of matrix material (16) enclosing a reinforcement element (14). The reinforcing elements (16) can be designed as longitudinally extending reinforcing fibers or as particles. This can increase the abrasion resistance and slow down the erosion.
