Recently I found a paper about incorporating corrugated skins in aircraft called 'Corrugated composite structures for aircraft morphing skin applications' by C. Thill, J.A. Etches, I.P. Bond, K.D. Potter and P.M. Weaver
The paper talks about how the application of corrugated skins might provide benefits in morphing skins. The paper mostly talks about the structural benefits, as requiring less force to change the shape. Even if the structure might be covered with an aerodynamic surface, I'm still interested in the aerodynamic properties of a corrugated surface.
If there's a wing surface with a corrugating perpendicular to the flow, as shown below (flow coming from the left).
How will such a surface incluence the effectiveness of non-corrugated ailerons?
I image such a surface would lead to a much thicker boundary layer, thereby greatly reducing aileron effectiveness.
I'm mostly interested in large corrugations(~50mm) and low speeds(~80km/h). I'm not asking about the lift generation of the surface itself, only the effect on a non-corrugated aileron.
