摘要： 研究了利用气动力辅助异面变轨时初始降轨段的近地点高度对变轨性能的影响 ;利用序列二次规划方法 ,考虑了最大热流限制 ,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 ,指出随着近地点高度的增加 ,变轨调节能力下降 ,对初值的鲁棒性变差 ;而所需最少特征速度与要求的倾角改变量有关 ,一般利用气动力辅助变轨近地点高度不宜过大

Abstract: The effect of perigee height on aeroassisted orbital plane change is studied.Using sequential quadratic programming,trajectories which minimize the impulse required to change the orbital plane and maximize the inclination change are calculated for different perigee heights.In each case,the stagnation heating rate is limited.Results show that with the increment of the perigee height,the ability to change orbital plane and robustness to the initial conditions are both decreased.In general,the perigee height should not be too large in aeroassisted orbital plane change.
