飞机扰动运动典型模态动画显示

Typical Mode Display of the Small Linear Disturbance Motion of an Aircraft

形象地表现线性小扰动运动方程的纵向和横航向典型运动模态，一直缺乏一种理想的方式。本文介绍了利用计算机动画制作技术，在计算机上将纵向和横航向５种典型运动模态隔离并模拟显示的一种方法。多视点、多角度地再现了它们的运动轨迹和飞机姿态的变化特征。这对于学习和掌握典型运动模态，分析扰动运动特征，理解飞行品质要求将起到很好的辅助作用。

There is no ideal way so far to represent the longitudinal and lateral motion mode of the small linear disturbance motion equation. This paper introduces a method by which the five typical modes can be separated and emulated. This method applies the technique of computer animation to the display of the flight trace and the character of the attitude of an aircraft at different visual angles and points.
