摘要
介绍了我国自主研制的轻于空气的飞艇 ,给出了其线性化的纵向运动状态方程。在此基础上 ,对该飞艇的纵向扰动运动进行了稳定性和能控性分析 ,指出其是不稳定的 ,但完全能控。将飞艇的纵向扰动运动分成 3个特征模态 。
A brief introduction of the LTA (Lighter-than-air) airship developed in China was made. And the linearized model for the airship longitudinal motion was presented. The stability and controllability of the longitudinal perturbation motion was analyzed based on the linearized equation. And a conclusion was made that the longitudinal perturbation motion of the airship is unstable and can be completely controlled. Three characteristic modes of the longitudinal perturbation motion were summarized.
