For many years, Ray W Prouty brought the black art of helicopter aerodynamics into a refreshing new light for the readers of Rotor & Wing International magazine. The original three books were published before the computer age revolutionized the book publishing industry, and none of the original text, drawings or photos were available electronically. In some cases, the original photos were no longer available, even from Ray's private collection, so other comparable photos were obtained from Ray.
Ray wrote these articles over a large time span, so in some cases, certain subjects were hit more than once. Rather than to try and cut anything out, everything is include in the three books, even when it was said more than once. Likewise, a few of the figures and photos repeat, but we think that you'll agree that the need to preserve the totality of what Ray has written should come first.
Well known helicopter test pilot and author Shawn Coyle (Art & Science of Flying Helicopters and Cyclic & Collective: More Art and Science of Flying Helicopters) was the initial driving force behind the effort to resurrect Prouty's works, and contributed his knowledge and keen eye in proof- reading. The result is a very readable, hefty 500 + page work, jam packed with extraordinary insights into helicopter aerodynamics, design, and handling.
Soft Cover 550 Pages.
This is the most clear and comprehensive textbook about helicopter aerodynamics Ive ever read. Written by a great aerodynamicist, addressed to pilots of any level. Just a few maths, only the essential physics needed to provide a real and smooth explanation of a so complex subject. Nice book, good price.
