Your actually asking 2 different questions.
Firstly..
Perhaps a rough shark skin surface combined with 10,000 micro movements a minute may help flow.
Well it will.. its about pressure and creating a change in the pressure of the airflow. You suggestion is similar to the golf ball dimple. Not all about drag reduction but about micro pockets of pressure differences.
Many people felt open bay wings were giving some improvement vs a perfect foam wing. Again this is explained by the pressure changes that occur along the chord line.
In the past much of this has been speculation but with programs like Ansys you can see how airflow reacts to different objects.
Micro scales, if you look.at a shark skin under electron microscope they look closer to a formular front wing crossed with a 3 way vortex generator.
Even if you wanted to copy the technology, I don't know how you might even come close to it.
I hate agreeing with brett because it happens to often.
Having studied boundaries and how they interact within certain conditions, im not convinced that there is anything to be gained by "vibrational resonance enhancing boundary layer efficiency "
I dont think the airflow molecules stay attached long enough to the surface to be bothered by a vibrating surface. The issue is the plane is flying through a very dynamic environment with à HUGE amount of pressure change.
Im not a rocket scientist, but I figure they vibrate ALOT more than our IC or electric ships do, if vibrational resonance was a "thing" they would see it there, and Ive not read anything to suggest its even close to "a thing"
The emergence of hunting in electric is simply solved by thrust line adjustment. Electric motors deliver power to the airframe differently thus might need a tweak.. not every design hunts .. some do it worse..
There is more vibration loosening control systems than electric does.. so that's a "thing"
