A golf ball goes twice as far using a dimpled surface. Many European aircraft (especially gliders) use dimple strips or zig-zag tape on propellers, wings, struts etc. Very few US aircraft use these products.
The dimples/holes/perforations are sometimes mechanically stamped onto a part, but more often a metallic or fiber tape is applied to a thick part of the surface. This is using existing after market technology and has nothing to do with "blow holes".
This question is not how it works it is HOW WELL it works!
What typical improvements in lift/drag are gained and are there any drawbacks to their use?
Dimples on golf ball reduces drag and doubles its range.
Dimple perforations or strips and zig-zag tape decrease drag on some aircraft surfaces.
