Reynolds numbers and circlar rotaion
Ok girls,
Here's the answer. The Reynolds number is the same, whether you model a flying Ant or or Flying Duck.
Ducks have the characteristic of eating from the bottom of rivers or ponds, or whichever low level water feture they happen to be around.
However, Ants live in Nests, and are little barstads if they bite you and inject you with a lump of nasty acid stuff!
So, to conclude, when you have a finite aspect ratio for a rotating blade, you need enough monkeys to write Hamlet for you.
Lots of love xxx
