大面质比太阳帆航天器Lissajous轨道转移研究

Research on the Lissajous Trajectory Transfer of Large Area Mass Ratio Solar Sail Spacecraft

考虑在Lissajous轨道上工作的太阳帆航天器,会受到地球阴影或太阳风等影响,造成航天器无法工作的情况,利用太阳光压作为推力提前进行Lissajous轨道转移。由于光压参数(锥角、钟角和光压因子)会改变平动点位置,利用新旧平动点流形拼接的方法,让逃逸航天器转移到新Lissajous轨道上,实现日地L2点的拟周期轨道转移。仿真结果证明除了改变锥角、光压因子外,钟角也能实现轨道转移,且光压因子对拟周期轨道的影响会比另外两项大。文章创新点在于首次利用三维人工平动点实现异宿Lissajous轨道转移,为太阳帆航天器在日地平动点周期轨道的转移以及躲避地球阴影等方面提供了参考。

Considering that the solar sail spacecraft working in the Lissajous orbit will be affected by the shadow of the earth or the solar wind,which sometime makes the spacecraft unable to work,we try to use the solar light pres⁃sure as the thrust to carry out the Lissajous orbit transfer in advance.Because the solar pressure parameters(cone angle,clock angle and solar pressure factor)will change the position of the libration points,we propose the idea of splicing the old and new libration point manifolds to transfer the escape spacecraft to the new Lissajous orbit to a⁃chieve orbit maintenance.The simulation results show that besides changing the cone angle and the solar pressure factor,the clock angle can also achieve orbit transfer,and the influence of the solar pressure factor on the periodic orbit is greater than the other two.This study provides a reference for the solar sail spacecraft in the aspects of peri⁃odic orbit transfer,orbit maintenance and avoidance of the earth's shadows.
