دانلود کتاب Art of the Helicopter

"The theory and dynamics of helicopter flight are complex and for the uninitiated, difficult. But in this book, British helicopter pilot and technical author John Watkinson sets out to simplify the concepts, and explain in lay-man's terms how a helicopter operates. Using photographs and over 400 diagrams, all aspects of rotary flight are covered including the history of rotor-craft, helicopter dynamics, rotors, tails, power plants and control. This is an excellent book for any helicopter enthusiast." Airforce, Fall 2004 "...clear and simple diagrams that aid verbal explanations of how helicopters are made." -AOPA, 2004 "The Art of the Helicopter is designed to de-mystify the complexity as it examines helicopter aerodynamic theory, design and performance. The book aims to discuss its subjects readably, begin each subject from first principles and build on those in a "clearly explained logical sequence using plain English and clear diagrams, avoiding unnecessary mathematics"... - Flight Safety Digest, May 2004
