摘要: 摘要: 针对月地返回轨道周期较长、不确定性较大的特点,结合我国主、副着陆场的分布情况,提出一种通过在月地返回轨道中实施双脉冲机动,以实现在应急条件下将再入平面调整至原再入平面以外的异面再入落区方法.应用一种迭代算法实现了在月地系统复杂引力场中求解Lambert问题的精确解;而后,结合最优的必要性判定条件以及模拟退火算法,应用一种交互式脉冲优化方法,可求得双脉冲机动的最优解为0.025 2 km/s,满足工程实际约束.

Abstract: Abstract:Aiming at the characteristics of Lunar exploration mission, to enhance the safety during reentry process and avoid adverse weather conditions which may appear on the main landing site, an impulse maneuver strategy in trajectory is put forward and optimized, which particularly aims at some emergency situations happening in prime landing site after transearth injection and having to land in backup landing site. Firstly, a practicable iteration method is proposed, which takes perturbation into account in solving Lambert problem. Subsequently, combining with Primer Vector and Simulated Annealing method, an interactive optimization is proposed, and the optimal energy consuming is 0.025 2 km/s, which is able to meet the constraints of engineering.  

Key words: Keywords:Lunar return; landing site transfer, Lambert problem, interactive optimizatio
