| Abstract: | The airborne electro-mechanical system of civil aircraft has complex structures and is difficult to do fault diagnosis.A fault diagnosis simulation platform is designed in this paper to carry out fault diagnosis more effectively. Taking into account of the different characteristics of the environmental control,landing gear and hydraulic system, corresponding methods are applied.The heat exchanger part of environmental control systems is diagnosed with parameter estimation,and the control components part of ... |
