This is a collection of Ray Prouty's columns from Rotor and Wing magazine from 1979 to 1992 dealing with advanced helicopter skills and advanced helicopter designs.

Ray W. Prouty is a Grand Elder of the helicopter industry. For many years, Ray brought the black art of helicopter aerodynamics into a refreshing new light for the readers of Rotor & Wing International magazine. Many of his articles were over time compiled into three thin books: Helicopter Aerodynamics, More Helicopter Aerodynamics, and Even More Helicopter Aerodynamics and resurrected into a single volume - Helicopter Aerodynamics.

Ray's career began in 1952, when, according to David Jenson of Rotor& Wing, "he put his Bachelors degree in Aeronautical Engineering from the University of Washington to application at Hughes Tool Co.'s Aircraft Division. He worked as a helicopter aerodynamicist at Hughes until 1954, when he moved his talents to Sikorsky Aircraft until 1956. Between 1958 and 1960, Ray was a stability and control specialist at Bell Helicopter, and then group engineer for helicopter aerodynamics at Lockheed Aircraft from 1960 to 1973. From 1973 until his retirement in 1987, Ray was back at Hughes Helicopters (McDonnell Douglas Helicopter Co.)."

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.
