英文摘要： The technology of civil aero-engine condition monitoring and fault diagnosis is one of the important factors of aviation security, and it also is a key technology of the development of civil aero-engine with our own intellectual property rights. Due to the lack of independent development monitoring and diagnosis system of civil aero-engine, domestic airlines depend on integrated diagnosis systems or remote diagnosis service supported by foreign Original Equipment Manufacturers (OEM). Through monitoring and evaluating the engine condition by using the Quick Access Recorder (QAR) data, the basic theory and key technology of civil aero-engine rotor and starting ignition system are studied. The achievements are verified combining with engine experiments and simulation experiments. The specific contents of this research included: the study on engine condition monitoring methods based on QAR data, rotor system fault diagnosis methods, starting ignition system fault diagnosis methods, and fault diagnosis experiments. On the basis of deep research on fault mechanism, an international advanced method system of civil aero-engine monitoring and diagnosis is constructed, and a relative system is developed. The purpose of this program is to break through the technical barrier of foreign countries, make sure the domestic civi
