No, stealthy aircraft don’t need to be unstable.
With limited computer power, you were limited to a certain number of elements. Double that if you presume bilateral symmetry. That led to the facet design of the F-117.
Unstable aircraft can have smaller control surfaces, but that is a second order effect, if that.
One can imagine that birds will damage a wind turbine more than they do now.
You silly Muggles.
Oh great, now they’ll start harvesting owls to make planes!
Didn't we first learn of this technology from Mel Gibson in the movie Conspiracy Theory describing the rotor blades on Black Helicopters?
Well, the technology first came to light in the well-known documentary "The Nude Bomb", where it was called "the shush-copter".
I would guess it reduces apparent wind noise by putting all the little wind sources out of phase with each other.
I suggest it might increase drag by making a bigger hole in the air compared to the same item with no carpet.
A properly shaped item with boundary layer trippers and stirrers could have reduced drag.
I learned of it from a class from Dr. Ufimisev.
Besides, boiled owl tastes like boiled owl, or so I have been told.
The British took the mufflers off their Phoenix drones during one of the Gulf wars. About half of their artillery calls for fire came from their drones.
After a bit, hearing the noise of the drone was enough for Iraqi army to withdraw.
Rather like the Germans putting whistles on the dive bomber Ju-87s in 1940.
I had one cruise over my dog as it walked. I've also had that "being followed" feeling in the woods. Turn around and find small owls shadowing me. I'm sure they do it to deer and elk, as well, waiting for them to kick rodents loose as they walk trails.
I’ve had canvasbacks set their wings directly overhead. Makes a pretty good ripping sound.
