G'day A.netters,

I'm currently conducting a project on wing tip devices in university. While I have consulted many books from our library on the subject, I also wonder if anyone who is a member of this site might be able to provide link(s) to any information they know of on the subject from the web.

I've read through the various threads on A.net related on the subject matter, and some of them have given me some useful information. What I'm looking for mainly, however, is theoretical information on wing tip devices (winglets, blended winglets, wingtip fences etc.)

At this stage, I am confident of the basic principles surrounding lift induced drag, so I am looking for literature that probes deeper into the reduction of wake vortices. As I also mentioned, I have access to a (fairly diversive) library, so physical references would be welcome too.

Anything anyone can provide would be apprieciated.

Best regards.

The only time I made a mistake was when I thought I was wrong...

While everyone here is against using Wikipedia, I would suggest looking at the article and seeing what it has to say, then check the references. Or if nothing else, use the reference list to find a ton of links to web pages talking about wingtip devices.

I see from your profile that you are in Manchester. So I am guessing you are part of MACE.
Well if that's the case then I suggest you may have no choice but to work up the balls to go and ask Filippone!!  Wink

I like the hoerner wingtips used on the STOL ch701/801 chris heintz designs; increased effective wingspan with none of the structural difficulties or added weight of a winglet.
The ultimate winglets though have to be the downward folding wingtips of the XB-70 valkyrie-

Tjc2, if you have the books, you understand lift induced drag, and remember that google is your friend, there's probably not much else you can gain from forum posts...

Thanks for the links folks, found some interesting articles thanks to the NASA TN search page, and google Scholar

Good guess, in fact I'm at Salford University, but A.net doesn't let me specify!
