Features: This book strives to be concise and advanced, focusing on explaining the fundamental concepts, principles, and methods of aircraft structural strength, stiffness, and aeroelasticity, reflecting the latest achievements in aerospace technology. The book consists of four chapters. Chapter 1 introduces external loads on aircraft, various strength design conditions, overload and safety factors, as well as fatigue loads and random load spectra. Chapter 2 covers the structural forms, load-bearing characteristics, structural force equilibrium, and force transmission of the three main components—wing, fuselage, and landing gear—with a dedicated section on new composite material structures and their load-bearing characteristics. Chapter 3 briefly outlines the evolution of structural strength calculations and current research needs, with a focus on the principles and methods of static strength, fatigue, and damage tolerance calculations. Chapter 4 emphasizes the research fields of aeroelasticity, aerodynamic issues in aircraft design, as well as the approaches, methods, and experience in addressing these issues. This book provides fundamental knowledge for aerospace technicians, researchers, and managers who are not specialized in aircraft structural strength and stiffness, enabling them to analyze and address related problems.
