Possibly the most complete book written to date on helicopters and helicopter flying. Covers subjects not covered by other manuals such as turbine engines, performance, flight manuals, automatic flight controls, legal aspects, introductory stability and control and multi-engine helicopters.
The modern helicopter is a sophisticated device which merges a surprising number of technologies together. This wide range of disciplines is one of the fascinations of the helicopter, but it is also makes a complete understanding difficult. Those searching for an understanding of the helicopter will find The Art of the Helicopter invaluable. John Watkinson approaches every subject associated with the helicopter from first principles and builds up in a clearly explained logical sequence using plain English and clear diagrams, avoiding unnecessary mathematics. Technical terms and buzzwords are defined and acronyms are spelled out. Misnomers, myths and old wives tales (for there are plenty surr...
Doss's charming, touching, and at times hilarious chronicle tells how each of the children, representing white, Chinese, Japanese, Filipino, Korean, Mexican, and Native American backgrounds, came to her and husband Carl, a Methodist minister. She writes of the way the "unwanted" feeling was erased with devoted love and understanding and how the children united into one happy family. Her account reads like a novel, with scenes of hard times and triumphs described in vivid prose. The Family Nobody Wanted, which inspired two films, opened doors for other adoptive families and was a popular favorite among parents, young adults, and children for more than thirty years. Now this edition will introduce the classic to a new generation of readers. An epilogue by Helen Doss that updates the family's progress since 1954 will delight the book's loyal legion of fans around the world.
The behaviour of helicopters is so complex that understanding the physical mechanisms at work in trim, stability and response, and thus the prediction of Flying Qualities, requires a framework of analytical and numerical modelling and simulation. Good Flying Qualities are vital for ensuring that mission performance is achievable with safety and, in the first edition of Helicopter Flight Dynamics, a comprehensive treatment of design criteria was presented. In this second edition, the author complements this with a new Chapter on Degraded Flying Qualities, drawing examples from flight in poor visibility, failure of control functions and encounters with severe atmospheric disturbances. Fully em...
