Aircraft Fatigue: Design, Operational and Economic Aspects contains the proceedings of the ""Symposium on Aircraft Fatigue—Design, Operational and Economic Aspects,"" held in Melbourne, Australia, on May 22-24, 1967. The papers explore the design and operational aspects of the fatigue problem in general aviation and transport aircraft, as well as the economic aspects of the fatigue problem as it affects both operators and manufacturers. This book is comprised of 21 chapters and begins with a description of an approach to structural reliability analysis based on order statistics and the expected time to first failure in a fleet of specified magnitude, along with its application to structures subject to progressive fatigue damage. The following chapters deal with structural load measurement and analysis; design and certification programs for a wide range of aircraft types including the Anglo-French and American civil supersonic transports; acoustic fatigue; and the design of joints. The detection of fatigue cracks in service and the effects of fatigue on the cost of design and operation of aircraft are also discussed. This monograph will be a useful resource for aircraft and aeronautical engineers as well as officials of civil aviation.

Fatigue occurs under cyclic loading and can significantly degrade the operational capability and safety of metallic aircraft components and structures. This book provides summaries of some metallic aircraft structural integrity issues, innovative but established examples of maintaining operational capability—airworthiness, and assessments of safe in-service fatigue lives. These topics are based on a through-life fatigue management philosophy that ensures safe and continued operation, including during life extensions that are almost inevitably required. This philosophy is underpinned by observations of the behaviour of fatigue cracks in actual structures subjected to realistic service loading conditions. The book includes topics like aircraft design requirements, individual aircraft fatigue loads monitoring, airframe fatigue testing, sources of fatigue-nucleating discontinuities, and prediction of fatigue crack growth from these discontinuities. All these aspects contribute to discussing methods of assuring the structural integrity and operational capability of realistically cracked structures. The book also discusses the exponential behaviour of lead or dominant cracks—those leading to first failure—and the practical significance of differences between fatigue fracture topographies produced under constant amplitude and variable amplitude loading. The book can be a valuable reference for researchers and professionals interested in aircraft fatigue management and allied fields.

This updated edition includes fatigue and sleep definitions as well as strategies for the measurement and assessment of fatigue. The aviation performance, mood, and safety problems associated with sleep restriction and circadian disruptions in operational settings are highlighted. The biological bases of fatigue are discussed so that the reader can understand that it is a real physiological phenomenon and not 'just a state of mind'. Both traditional and newly-developed scientifically-valid countermeasures are presented, and a variety of data from diverse sources are included to provide readers with a 'toolbox' from which they can choose the best solutions for the fatigue-related problems that exist in their unique operational context. In addition, an essential overview of Fatigue Risk Management Systems is included to provide the basic structure necessary to build and validate a modern, integrated approach to successful fatigue management. The book is of interest to aviation crews in both civilian and military sectors--managers as well as pilots, flight crews, and maintainers. It aims to be user-friendly, although scientific information is included to help the reader fully understand the 'fatigue phenomenon' from an evidence-based perspective as well as to enhance the reader's appreciation for the manner in which various counter-fatigue interventions are helpful.

Aircraft Sustainment and Repair is a one-stop-shop for practitioners and researchers in the field of aircraft sustainment, adhesively bonded aircraft joints, bonded composites repairs, and the application of cold spray to military and civil aircraft. Outlining the state-of-the-art in aircraft sustainment, this book covers the use of quantitative fractography to determine the in-service crack length versus flight hours curve, the effect of intergranular cracking on structural integrity and the structural significance of corrosion. The book additionally illustrates the potential of composite repairs and SPD applications to metallic airframes. Covers corrosion damage assessment and management in aircraft structures Includes a key chapter on U.S. developments in the emerging field of supersonic particle deposition (SPD) Shows how to design and assess the potential benefits of both bonded composite repairs and SPD repairs to metallic aircraft structures to meet the damage tolerance requirements inherent in FAA ac 20-107b and the U.S. Joint Services

The document is comprised of papers presented at the Air Force Conference on Fatigue of Aircraft Structures and Materials, sponsored by the Air Force Flight Dynamics Laboratory (AFFDL) and the Air Force Materials Laboratory (AFML), Air Force Systems Command. The purpose of the Conference was to discuss technological advancements in fatigue and fracture theory. The Conference was comprised of ten technical sessions (including two panel discussions) entitled 'The Role of Materials in Structures'; 'Fundamentals I + II'; 'Criteria'; 'Fracture I + II'; 'Phenomena I + II'; 'Analysis'; 'Design and Service Experience'. A total of fifty-six technical papers were presented.
