Fundamentals of Mechanics of Intelligent Aircraft is one of the textbook volumes of Intelligent Aircraft System Theory and Technology. This book is designed for graduate students, undergraduate students, aircraft system engineers and professional designers based on intelligent aircraft design technology. This book tries to follow the teaching guiding ideology of "interest orientation, theory first, learning to apply, combining the master, master and doctorate", and systematically introduces the basic theory and method of intelligent aircraft design mechanics, including Chapter 1-18 material mechanics and Chapter 19-42 Theoretical Mechanics.
