PS: Pitts, did your BSc (H) (helicopters?) tell you how induced drag is modelled - from a scientific interest, rather than a practical aviation interest?
Andy,
(H) Honours. Not really the same thing but as close to a British uni equivelant as I've ever been able to find. Basically it was a US standard 4 year degree, whereas, I believe, a British BSc is a three year degree.
Can't remember about the drag model, to be honest. That was 20 years ago and I'm not even sure where the book is any more. I'm sure we did talk about drag quite a bit but I can't remember what models we used for it. Sorry.
