Default RE: wing tip vortices trails


ORIGINAL: tIANci
But fluid dynamics on a real plane and a small plane is not the same. Just like the Reynolds numbers ... however, it would be cool to see it happen on a RC plane!
"

?? - I kind of thought it was the same, except for the specific differences due to low Reynold's numbers, mostly the difficulties maintaining laminar flow and whatever inefficiencies that result. But I am pretty sure the primary reason this must be rarely or ever seen on models is that we simply don't work with anywhere near the same kinds of wing loading and the resulting levels of pressure differential and dynamic pressure - otherwise I would have to think we'd need to start looking at aluminum wing skins and way better internal structures and whatever other voodoo would be manatory to keep the wings from disintegrating.

HornetFitter - thanks for the first hand explanation!
