Features: This book is a monograph on the theory of aircraft gas turbine engine fault diagnosis based on mathematical models (fault equations) and is one of the main achievements of the National Natural Science Foundation of China-funded project "Aircraft Engine Fault Diagnosis Analysis System" (Project No. 59876046). The book consists of 15 chapters and 4 appendices. It discusses the establishment methods of engine fault equations (including small deviation fault equations and empirical fault equations), introduces the mathematical foundations required for fault diagnosis theory, including optimal estimation and optimization algorithms, as well as linear statistical model theory. It also introduces the theory of engine fault diagnosis, primarily the main factor model for engine fault diagnosis proposed by the book's author, including the basic principles of the main factor model, the theory of fault correlation criteria, and various solution algorithms for overdetermined and underdetermined main factor models. The book discusses the impact of multicollinearity and methods to overcome it, and introduces the effectiveness evaluation of engine fault diagnosis. This book can serve as a textbook for graduate and undergraduate students in the fields of aircraft propulsion engineering and aviation maintenance engineering in higher education institutions, as well as a reference for faculty members, undergraduate and graduate students, and technical personnel engaged in engine condition monitoring and fault diagnosis.
