综合相关文献,提炼出调相轨道设计,入轨精度对调相的影响评估和可变推力下入轨精度改进效果分析等快速交会对接关键技术问题。对比天宫和国际空间站的对接模式差异,比较分析了3种备选快速对接调相轨道的优缺点,给出了合理可行的实现建议。仿真分析表明,圆调相轨道、增大轨道差和双调相轨道配置有利于快速交会对接的灵活实现。通过对调相轨道和入轨精度匹配性的量化分析,提出了运载火箭进一步提高入轨精度的实现方法,为快速交会对接方案提供了有益参考。
Based on the relevant literature, the key technical issues of rapid rendezvous and docking, such as the design of phase-modulated orbit, the impact assessment of orbital accuracy on phase modulation, and the analysis of the effect of orbital accuracy improvement under variable thrust, are refined. Comparing the differences between docking modes of Tiangong and ISS, the advantages and disadvantages of three alternative fast docking phase-and-shoot orbits are analyzed and compared, and the reasonable and feasible suggestions are given. The simulation results show that the flexible circular orbit, the increased orbit difference and the dual-phase orbit configuration facilitate the flexible realization of the rendezvous and docking. Through the quantitative analysis of the matching accuracy between phase-modulated orbit and orbit, the method to realize the orbital accuracy of the launch vehicle is proposed, which provides a useful reference for the rapid rendezvous and docking.
