本文运用外弹道学理论对双稳态类型航弹的运动稳定性作了研究,运用无量纲化运动方程组导出了双稳态固定尾翼航弹和双稳态自由旋转尾翼航弹的动态稳定性条件及它们的稳定性区域图。分析了各参量对双稳态航弹稳定性的影响,阐明了尾翼自由旋转后对运动稳定性带来的好处。本文的某些结论和附图沿用了文献(5),作者仅作了些发挥和深入。
In this paper, we study the stability of the bistable type of missile using the theory of the external ballistics. The dynamic stability of the bistable fixed-wing and the bistable free-swinging stabilizer is derived by using the non-dimensional equations of motion Conditions and their stability area map. The influence of various parameters on bistable missile stability is analyzed, and the benefits of stability of the tail after free rotation are clarified. Some of the conclusions and drawings in this article follow the literature (5), the author made some only play and deepen.
