摘　　要：根据军用飞机飞行参数记录系统提供的飞行数据,提出一种利用Cardinals三次样条曲线进行航迹生成的算法。经过对离散点航迹误差修正及样条曲线的讨论,给出实时计算任意时间点飞机质心位置的公式,为开发可在普通PC机上运行的军用战机飞行过程再现软件,提供了条件。According to the data form fighter's FDR,an algorithm was presented that using the Cardinals cubic spline curve to create flight trajectory.With the discussion of correcting discrete flight lines and spline curve,an function to calculate plane's centroid place anytime was proposed.It was used in software of fighter trajectory emersion,and result was acceptable.
