The second edition of Principles of Helicopter Flight from ASA is now available in eBook format as well as in an eBundle (print book + eBook).
The book by Walter J. Wagtendonk was previously only available in print.
The textbook examines the aerodynamic factors associated with rotor stalls, mast bumping, and wind effect, as well as maneuvering flight to include the hover, forward flight, flare, and autorotation.
Helicopter design and components, performance, and weight and balance are covered, along with special techniques such as different types of takeoffs and landings, operating on sloping surfaces, sling operations, mountain flying, and helicopter icing.
This second edition benefits from additional discussion of the NOTAR system and strakes, as well as frequently misunderstood principles of airspeed and high altitude operations.
The book concludes with a multiple-choice practice examination. Used in conjunction with quizzes for each chapter, the reader can test their understanding of helicopter aerodynamics.
