Automatic wing wipers.

What are these.

Doesn’t the thread title answer the question?

 

[Dana]

On a sailplane with a laminar flow wing, too many bugs could disrupt the airflow enough to increase drag. Whether the increase is enough to warrant such a fix I don't know, it may be a solution in search of a problem?

Clever design, though.

Something like this could work?

I was waiting to see that thing fly off the end of the wing ;-)

Dang! Glider pushers are serious competitors.
I've been watching the competition in Europe. Crazy.

They're pulled out by aerodynamic forces, and then retracted by a line, either with a crank or motor. Some of these competition gliders lose 10-20% glide ratio is there's buildup on the leading edge, so I guess for them it is worth it.
