摘要:
研究了太阳帆航天器在哑铃形小行星引力场内的悬停探测可行性问题。哑铃形小行星代表了一类细长形的小行星,文中首先建立哑铃形小行星的简化动力学模型。针对可变反射面积的太阳帆,给出其在小行星引力场内的悬停动力学方程,并仿真求解了哑铃形小行星附近的太阳帆可行悬停探测区域。

Abstract:
The feasibility of hovering flight over elongated asteroids by using solar sails is investigated in this study. Elongated asteroids represent a family of natural elongated bodies. A simple approximate model is first constructed for these elongated asteroids. Dynamic equations of hovering flight are obtained for solar sails with the ability of active sail area control. Numerical simulations are made to illustrate the feasible area of hovering flight in the gravitational field of elongated asteroids.
