摘要
飞行器的动态特性分析在整个飞行器设计过程中起着非常重要的作用。本文介绍了动态分析的研究方法和基本理论。基于小扰动理论,针对某飞行器在典型飞行轨迹上选定的部分特征点进行了纵向和侧向的动态特性相关参数的计算,主要对其纵向和侧向的稳定性、操纵性进行了初步分析,并对其阶跃响应过程进行了仿真分析,定性和定量的评定了该飞行器的动态品质,初步获得了该飞行器的动态特性。
The A/C dynamic characteristics analysis is very important in whole aircraft design. The paper introduces the study method and basic theory for dynamic analysis. Based on the small disturbance theory,the relevant parameters of longitudinal and lateral dynamic characteristics on some points selected from the typical flight path are computed,the longitudinal and lateral stability and controllability are analyzed primarily,and simulation analysis are conducted for the step response process,assessing the dynamic quality qualitatively and quantitatively,obtaining the dynamic characteristics of the aircraft primarily.
