I'm not certain dimples would make much difference in a well designed
airfoil wing or prop or fusalage. �Maybe something that had an awkward
shape, i. e., a strut, would benefit the most.
If dimples were an "improvement", why do airplane makers bother with
smoothing out the dimples from flush rivets?
The Reynolds number is over 100,000 for anything bigger than a drone
going over 10 mph.
