针对大气层内非自旋质量矩控制飞行器,提出了一种采用圆环形滑道代替传统的直角正交滑道的布局配置方案。首先,利用牛顿第二定律及动量矩定理建立了基于此布局方案下的飞行器动力学模型,并且得到了弹体动力学的简化模型,通过数值仿真验证了该简化模型的正确性。与直角正交滑道相比,这种圆环形滑道布局的两个滑块可以为系统提供冗余防故障措施,可以大幅度地提高质量矩的控制能力。最后应用最优化理论得出了一种获得期望质心偏移的三滑块位置优化算法,解决了圆环形滑道滑块运动可能产生的碰撞问题。
In view of the non-spin moment of mass control aircraft in the atmosphere, a layout scheme using a circular ring instead of a traditional orthogonal quadrature slide is proposed. First of all, based on the second law of Newton’s law and momentum moment theorem, a dynamic model of the aircraft is established based on this layout scheme, and a simplified model of projectile dynamics is obtained. The correctness of the simplified model is verified by numerical simulation. Compared with the orthogonal cross-slide, the two sliders in the circular slide layout can provide redundant fail-safe measures for the system, which can greatly improve the control of the mass moment. Finally, a three-slider position optimization algorithm that can get the desired center of mass offset is obtained by applying the optimization theory, which solves the possible collision problem of the circular slide rail.
