设计参数对气动力辅助异面变轨性能的影响

较全面地研究了利用气动力辅助异面变轨时的两个设计参数，即质量面积比和最大升力系数对变轨性能的影响。利用序列二次规划方法，考虑了最大热流限制，建立了优化模型。通过对最大倾角改变量和最少特征速度两类问题的优化计算，指出对较小的倾角变量，可通过降低质量面积比或提高最大力系数来满足变轨能力要求，当倾角改变量较大时，应以降低质量面积比为主。

Effect of design parameters on aeroassisted orbital plane change

The effect of design parameters, i.e. mass to area ratio and maximum lift coefficient, on aeroassisted orbital plane change is studied in this paper. Using sequential quadratic programming, trajectories which minimize the impulse required to change the orbital plane and maximize the inclination change are computed for different parameters. In each case, the stagnation heating rate is limited. Results show that by either decreasing mass to area ration or increasing maximum lift coefficient could achieve a small inclination change. When the inclination change is large, it is better by decreasing mass to area ratio.
