Presents examples of lessons learned in airplane design since 1945. The lessons are largely drawn from the aircraft design and accident/incident literature. The author hopes that this book will contribute to the safety of flight. A brief summary is presented of safety statistics, certification and operational standards, safety standards and their relationship to design in general. Accident/incident discussions are presented in the following areas: operational experience; structural design; flight control system design; powerplant installation design; systems design; manufacturing and maintenance; aerodynamic design; configuration design and aircraft sizing. In each case the discussion starts with the recounting of a problem which arose. Then the probable cause of the problem is identified, one or more solutions are indicated and finally a lesson learned is formulated. Since many designers will eventually become program managers, it is instructive to recount some trials and tribulations associated with marketing, pricing and program decision making. As is shown by many examples in this book, safety of airplanes often starts in the design phase. However, sometimes the certification process itself, for whatever reason, fails. This book will be useful to practicing design engineers, test pilots and program managers. It can be used in the classroom to help in the education of future aircraft designers and engineering/maintenance personnel. (Publisher's blurb)

Over the past eight decades, developments in vertical lift aircraft--both helicopters and vertical/short takeoff and landing (V/STOL) planes--have given the American military unparalleled capabilities on the modern battlefield. The U.S. has led the world in vertical lift technologies with the help of some of the brightest minds in this field--Igor I. Sikorsky, Arthur M. Young, Frank N. Piasecki, Charles H. Kaman and Stanley Hiller, Jr., to name a few--and by having the industrial prowess to make their concepts reality. This book provides a concise historical survey, including technical specifications, drawings, and photographs of every type of helicopter and V/STOL aircraft developed for the U.S. military, from the earliest examples tested in 1941 and 1942, up to the newest prototypes.

This is one of a series of reports on the lessons learned from past research related to lift-fan aircraft concepts. An extensive review is presented of the many lift-fan aircraft design studies conducted by both government and industry over the past 45 years. Mission applications and design integration including discussions on manifolding hot gas generators, hot gas dusting, and energy transfer control are addressed. Past lift-fan evaluations of the Avrocar are discussed. Lessons learned from these past efforts are identified. Deckert, Wallace H. Ames Research Center...
