This important text covers all aspects of structural loads analysis and provides some continuity between what was done on earlier airplane designs and what the current applications of the present regulations require.
The increasing demand for new civil aircraft pushes aircraft manufacturers to develop innovative solutions that lead in particular to mass reductions. One way to achieve these kinds of improvements is the use of multidisciplinary analysis and optimization. In this sense the intention of this PhD thesis is to develop a multidisciplinary framework in order to quantify the impact of load alleviation function parameter changes on structural components like the wing and fuselage in terms of resulting mass changes. The developed iterative process chain covers the loads calculation including an active load alleviation system, a structural assessment of the wing and fuselage components and a dedicated feedback loop in order to update mass and stiffness properties of the loads calculation model. The study shows that significant mass reductions are achievable while on the other hand estimated mass penalties are irrelevant.
The major objective of this book was to identify issues related to the introduction of new materials and the effects that advanced materials will have on the durability and technical risk of future civil aircraft throughout their service life. The committee investigated the new materials and structural concepts that are likely to be incorporated into next generation commercial aircraft and the factors influencing application decisions. Based on these predictions, the committee attempted to identify the design, characterization, monitoring, and maintenance issues that are critical for the introduction of advanced materials and structural concepts into future aircraft.
Introduction to Aircraft Structure Analysis, Third Edition covers the basics of structural analysis as applied to aircraft structures. Coverage of elasticity, energy methods and virtual work set the stage for discussions of airworthiness/airframe loads and stress analysis of aircraft components. Numerous worked examples, illustrations and sample problems show how to apply the concepts to realistic situations. As a self-contained guide, this value-priced book is an excellent resource for anyone learning the subject. Based on the author's best-selling text, Aircraft Structures for Engineering Students Contains expanded coverage of composite materials and structures“/li> Includes new practical and design-based examples and problems throughout the text Provides an online teaching and learning tool with downloadable MATLAB code, a solutions manual, and an image bank of figures from the book
In this report the author describes: (1) development of advanced methods of structural weight estimation, and (2) development of advanced methods of flight path optimization. A method of estimating the load-bearing fuselage weight and wing weight of transport aircraft based on fundamental structural principles has been developed. This method of weight estimation represents a compromise between the rapid assessment of component weight using empirical methods based on actual weights of existing aircraft and detailed, but time-consuming, analysis using the finite element method. The method was applied to eight existing subsonic transports for validation and correlation. Integration of the resulting computer program, PDCYL, has been made into the weights-calculating module of the AirCraft SYNThesis (ACSYNT) computer program. ACSYNT bas traditionally used only empirical weight estimation methods; PDCYL adds to ACSYNT a rapid, accurate means of assessing the fuselage and wing weights of unconventional aircraft. PDCYL also allows flexibility in the choice of structural concept, as well as a direct means of determining the impact of advanced materials on structural weight. Ardema, Mark D.

Many of the aircraft that form the backbone of the U.S. Air Force operational fleet are 25 years old or older. A few of these will be replaced with new aircraft, but many are expected to remain in service an additional 25 years or more. This book provides a strategy to address the technical needs and priorities associated with the Air Force's aging airframe structures. It includes a detailed summary of the structural status of the aging force, identification of key technical issues, recommendations for near-term engineering and management actions, and prioritized near-term and long-term research recommendations.
