Abstract: The simulation is a normal way to analyze system performance of aircraft landing gear and hydraulic system. Health management of aircraft systems is now a research focus. In this paper, principle and fault characteristics of landing gear hydraulic retraction/extension system were first studied. Simulation model based on AMESim software was established and the factors affecting on the working performance of the system was analyzed. Various outputs of several components vs different health situations were obtained, which lay the foundation for further fault diagnosis and health management.

Key words: landing gear hydraulic retraction/extension system, simulation, AMESim, health management
