So wingtip design, has always been a fascination of mine.
That being said, I always pay particularly close attention to wingtip design on essentially every aircraft that typically utilizes such devices (IE: Sailplanes, racing aircraft, efficiency oriented aircraft, etc.)
So, this is a discussion regarding specifically the CRJ (and global express) winglet. Has anyone else noticed the (what I call) "flared chord" at the root of the winglet? It is unlike any winglet I have seen, where it appears to try to manage the intersection more efficiently. In my own studies (strictly CFD), I have found little to no benefit, and only added complexity. I could be doing something entirely wrong but it certainly doesn't seem to produce a noted benefit. (granted, I am not working on bombardier budget either :lick
So, assuming everyone here has at least a basic understanding in winglet design, does any one have any clues as to specifically what this achieves?
