| Abstract: | Through the analysis of typical aeroengine fault,using RBF neural network,this page constructs performance parameters under the throttle angle of engine and studies the fault characteristics as the training sample.Comparing with an expected value between test samples and training samples,we can get the decay degree of engine performance and the aeroengine performance evaluating model.By large amounts of aeroengine recorded flight data tested,plenty of other vehicles validated that this method can diagnose e... |
