摘要
介绍了太阳帆航天器在进行探月飞行时,非理想帆面的推力计算;重点分析了在轨长时间运行时空间环境对帆面光学系数及轨道漂移的影响.计算结果表明,太阳帆光学性能的退化对总推力、特征加速度和光压数的演化不可忽视,高精度深空探测轨道的设计要考虑空间环境因素.
Based on a non-perfect reflection model of light pressure propulsion, the effects of space environment on the optical coefficients and orbit drifting of solar sail spacecraft carrying out long-term mission of lunar exploration were analyzed. The results suggest that the optical degradation of solar sails can not be neglected in studying the evolution of total propulsion, characteristic acceleration and lightness number. The role of space environment must be included in high-precision trajectory design of deep-space missions.
