| 摘 要： | 本文通过六自由度弹道方程数值模拟了再入弹头非对称气动力和非对称静、动导数对弹头滚转异常的影响;阐述了非对称气动力及非对称静、动导数产生的机理。本文利用作者建立的近似计算和数值计算方法,计算了典型的非对称再入弹头的气动力,定性分析了非对称气动力随弹头几何参数的变化规律,对再入弹头设计有重要的参考价值。

| Abstract: | An effect of asymmetrical aerodynamic derivative of the static and dynamic stability are presented on rolling resonance of re-entry body. Those are simulated by 6-D equations of motion. The mechanism of inducing asymmetrical aerodynamic characteristics is described. Small asymmetrical force for a typical body is calculated with the approximate and the numerical method. The results show that there is the law of variation of small asymmetrical aerodynamic force with re-entry body geometry parameters such as semi-angle, nose bluntness. It's importance for designing re-entry body. |
