| Abstract: | A new method for fault diagnosis of aircraft fuel system using BP network as a way to prevent the problem of fault diagnosis of aircraft system is presented.By designing multilayer neural network model of aircraft fuel system,knowledge base and infer engine are built,and by means of CB tool,the relevant software environment is set up.Consequently the neural network fault diagnostic expert system of aircraft fuel system is successfully developed.The emulational results prove that the intelligence of expert system works perfectly and the faults of fuel system are diagnosed well and fast;furthermore,effective methods of reconstruction can be brought forward in the expert system.It is entirely practicable in aircraft fuel fault diagnosis system. |
