| 摘 要： | 由于存在干扰,飞参系统记录的发动机参数中,经常会有不少间断点和奇异值.为了利用数据对发动机性能趋势进行预测,必须对数据进行预处理.分析了航空发动机作为一个系统,其各主要输入和输出参数之间存在的函数关系.研究了利用广义回归神经网络和参数之间的关系对数据进行预处理,结果得到了较为正常的数据,证明该方法是有效的.

| Abstract: | 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 ... |
