Aircraft Flight Vibration Prediction Technology

摘要：

It introduces the main source and character of aircraft flight vibration. For the non-linear relation between aircraft flight vibration and flight parameter such as mach number, altitude, and attack angle, aircraft flight Vibration prediction technology based on Back Propagation neural network is proposed. It describes the building process of the prediction model, and determines the value of each parameter in the model. Comparing result between aircraft flight vibration field measurement value and predicted value shows that the prediction method has good precision.
