boeing --tried same sort of idea on 747 wings by fixing patterned tape on the first 1/3 of the wing --which is where all the lift is made --tests showed a 5% decrease in drag -- but you don,t see new aircraft using it --so must be some reason why not --could be it made ice sticking to leading edge harder to shift /--dont know --but never got as far as use in real world
