Application of BP Neural Network in the Fault Prediction for a Certain Aero Motor

In order to make the aero motor run safely and reliably, fault prediction of the aero motor is needed. The fault prediction theory is introduced; an algorithm of modeling is proposed for the neural network in the prediction courses, and it is used in the prediction for aero motor. The test results illustrate that the fault prediction based on BP neural network has high accuracy and good prospects.
