To effectively monitor the performance status and early warning of engine starting system, the multi-indicator fusion strategy for health monitoring of engine starting system is proposed by comprehensively considering the starting valve and starter performances. Combined with the operation principle of starting valve and starter in the starting system, the quick access recorder (QAR) parameters that can reflect the performance change of starting process are selected; the pressure value at the entrance of the starter is obtained by using the auxiliary power units (APU) pressure attenuation coefficient, and then the work energy is determined by integrating the starting process pressure; the operating time of the valve is calculated by the starting valve air volume-time curve, and the health indicator threshold of the valve and starter is obtained by using the regression fitting method and three-parameter Burr distribution, to realize the health state monitoring of the engine starting system. The results show that the accuracy of proposed method for engine health status monitoring can reach 90%, which can effectively reflect the performance changes of engine starting system, and can provide a reference for engine health management and predictive maintenance formulation strategies.
