Integrated modular avionics (IMA) is one of the most advanced systems. Its performance greatly impacts on the working condition of aircraft. For enhancing the safety and reliability of aircraft, this paper researches on modeling of IMA degradation. Since the intermittent fault occurs in the degradation of electronic device, it can be considered as one of the characteristics of degradation. The IMA...
The Prognostic and Health Management (PHM) technology has been widely used as means of improvement for reliability, safety and availability of new generation weapons and commercial products, achieving autonomic logistics. In avionics system, European countries and the USA have been promoting the development, maturing of PHM critical technologies and their applications in military and commercial aircrafts...
Based on the correlation theory, the fault diagnosis reasoning method, which is established upon the assumption that system has two states: health and fault, can obtain diagnostic reasoning model and realize fault diagnosis.is, In addition to health or fault state, there is a clear intermediate state in many electronic products, namely sub-health state. This state is neither a health state nor a fault...
