Thanks for mentioning the used book site. Will look into it, and also look deeper into 'Rotary Wing Aerodynamics'.
Coincidentally, I ordered Prouty's new book a couple of weeks ago. Its called 'Military Helicopter Design'. As you know, he has a very clear way of writing so it should make for interesting reading.

Correction to previous post.
The book is not new. It was originally published in 1989, with corrections in 1998 reprint, but it looks very interesting.
