Abstract

The paper considers the possibility of cargo relocation without fuel costs along a tether connecting two heavy space stations by a spacecraft with a controlled solar sail. The spacecraft’s relative motion dynamics is studied within the context of a model problem that assumes that the stations describe one heliocentric orbit, the solar sail is a perfect reflective flat panel, and the tether realizes an ideal unilateral handrail constraint that restricts the spacecraft relative motion to an ellipsoid. It is noted that, if the distance between stations is sufficiently small and the ratio of the sail area to the spacecraft mass is on the same order of magnitude as in already-implemented space missions, solar radiation is the main factor that influences the spacecraft’s motion in the orbital frame of reference. The problem of searching a set of pairs of points, between which relocation with a permanently oriented sail is possible, is solved for the pairs that belong to the intersection of the ellipsoid boundary and the plane of the stations’ orbit. The duration of the spacecraft relocation between the ellipsoid poles is estimated for the case of the sail oriented orthogonally to the solar rays. Also, the duration of the fastest relocation between poles is computed using special sail orientation control laws, including the case of zero initial and final velocities.

太阳帆沿扶手约束运动的模型问题

摘要本文考虑了通过带有可控太阳帆的航天器沿连接两个重型空间站的系绳进行无燃料成本的货物搬迁的可能性。该模型假定空间站描述一个日心轨道，太阳帆是一个完美的反射平板，系绳实现了一个理想的单边扶手约束，将航天器的相对运动限制在一个椭圆形内。据指出，如果站点之间的距离足够小，并且帆板面积与航天器质量的比例与已执行的空间飞行任务的比例相同，太阳辐射就是影响航天器在轨道参照系中运动的主要因素。在椭球边界和空间站轨道平面的交点上寻找一组点对，在这些点对之间用永久定向帆板进行重新定位是可能的，这个问题是针对这些点对解决的。在帆板方向与太阳光线正交的情况下，对航天器在椭球体两极之间重新定位的持续时间进行了估算。此外，还利用特殊的帆板定向控制法计算了两极之间最快重新定位的持续时间，包括初始速度和最终速度为零的情况。
