Abstract: In order to improve the fault handling capability of the test crew in the aero-engine development process,a visual test-run semi-physical simulation system is designed to conduct fault simulation in the air start system,fuel system and engine system.A fault processing model combining fault mathematical model,phenomenon mathematical model and troubleshooting method is established to realize fault setting,phenomenon and process simulation,and key performance index for fault elimination operation is evaluated according to system response time and precision.Simulation results show that the system can realize the visualization of the aero-engine test-run failure process and can directly reflect the fault phenomenon and the process.

Key words: aero-engine test-run, fault diagnosis, fault simulation, fault processing model, critical performance index
