摘要: 薄膜太阳帆(FSS)是集推进、发电和姿轨控功能于一体化的超大型挠性太阳帆式航天器,通过调整薄膜反射率产生可变推力和力矩,实现其姿态和轨道运动控制。结合薄膜太阳帆在地球同步轨道运行时的受力特性进行了轨道漂移分析。通过建立薄膜太阳帆动力学模型及受力模型,提出了调整帆面角度轨道修正方法以及基于薄膜光压力矩角动量卸载的长期在轨对日定向面内双轴动量轮稳定控制方法。通过系统仿真验证表明所提的轨道修正和对日定向控制方法是合理有效的,可使薄膜太阳帆长期在定点位置维持对日定向。

Abstract: The film solar sailcraft (FSS) with variable reflectivity is a huge flexible spacecraft capable of propulsion, electric power generation, and attitude and orbit control. The FSS can generate force and torque for attitude and orbit control via varying film reflectivity. In this paper, the orbit drifting motion is analyzed according to the force characteristics of the FSS on the geostationary orbit, and the dynamics model and force and torque model of variable film reflectivity for the FSS are built respectively. Based on the proposed models, an orbit correction method is presented to change the attitudes of the FSS. A stable and reliable attitude control method with double momentum wheels fixed in the plane of the FSS is also proposed. The momentum accumulation of the wheels for attitude control can be unloaded by the solar torque produced from variable film reflectivity. The mathematical simulations show that the proposed methods are reasonable and fit for engineering applications, enabling the FSS to work at a fixed longitude position over a long period of time.

Key words: film solar sailcraft, geosynchronous orbits, attitude and orbit control, super large flexible spacecraft, film reflectivity
