Flight Data Pretreatment Based on Generalized Regression Neural Network Approaching

A FDR(flight data recorder) records data of some parameter of an aeroengine.Because of jamming,there are some abnormal data in flight data.The data must be pretreated so that it can be used to forecast performance trends of an aeroengine.The interrelation between the inputs and outputs of a system of an aeroengine was analysed.Pretreatment of flight data using Generalized Regression Neural Network was studied on the base of relation of parameters.As a result,normal data is worked out.It was proved that the method was available.
