Research on Health Assessment of Hydraulic Pumping Source System for Civil Aircraft

Aiming at the high fault rate and the problem of high fault harmfulness of civil aircraft hydraulic pumping source system, the fuzzy synthetic evaluation algorithm is researched. Aiming at the complex system, more influenced factors, the analytic hierarchy process (AHP) is presented to establish the weight set. Aiming at the real-time need of health assessment, the expert system is used to build membership function. Finally the method is validated by a set of data of that system.
