| 摘要: |
| 主要针对空间系绳系统辅助返回的大气层再入条件进行了计算及相关影响因素的分析。首先描述了系绳辅助返回过程，再次建立了系统在轨道坐标系下的动力学模型、舱体回摆模型，给出了再入条件的计算过程。分析了不同轨道高度下绳长、最大偏离角、系绳质量、切断角对再入条件的影响以及满足再入条件下，不同轨道高度下的绳长范围。基于以上分析，给出了再入速度与轨道高度和绳长、最大偏离角与绳长、再入角与最大偏离角和绳长的解析表达式，给出了再入条件与绳长的二阶关系表达式，并进行了验证。该研究为今后利用系绳系统来实现辅助返回的相关参数的选择提供了一定的参考，为空间系绳系统辅助返回技术的研究提供了重要的理论依据。 |

| Abstract: |
| The atmospheric reentry conditions for a space tether-assisted return system are calculated,and its influ-ence factors are analyzed based on the space tether-assisted deorbit system.The space tether-assisted return processis described,its dynamic model and the backswing model of the capsule in the orbit coordinate system are estab-lished,and the results on the calculation of reentry conditions are given.The influence on reentry conditions bytether length,maximum deviation,tether mass,cut angle and the range of tether length that meet the reentry condi-tions under different altitudes are analyzed.The analytical expression among reentry velocity,altitude and tetherlength,the expression between maximum deviation angle and tether length and the expression among reentry angle,maximum deviation angle and tether length are obtained.Finally the second order expression between reentry condi-tion and tether length is obtained and verified.This study has reference value for choosing the parameters of a futuretether-assisted return system and calculating its return conditions. |
