摘要
飞参数据记录系统中各通道参数存在着一定的时间差,影响着飞参数据在实际中的应用,针对这种现象,在分析三次样条插值的基础上利用Matlab对某架次飞参数据的排气温度通道进行插值标校仿真。结果表明该方法具有有效性和工程实用性,方法已在基于飞参数据的多项应用中得到了较好的推广。
Different parameters which records in different channels of FDRS（ flight data record system） are asynchronous, which affects the practical application of flight data. In reaction to the phenomenon, a MATLAB- based simulation to time calibration of exhaust temperature parameter recorded in a flight data is carried out based on research of cubic spline interpolation. The results show that the method is effective and useful to solve engineering problems, and the method is promoted in any applications based on flight data.
