A shape of the satellite’s solar sail membrane is essential for unloading angular momentum in the three-axis stabilized attitude control system because the three-dimensional solar sail can receive solar radiation pressure from arbitrary directions. In this paper, the objective is the shape optimization of a three-dimensional membrane-structured solar sail using the angular momentum unloading strategy. We modelled and simulated the solar radiation pressure torque, for unloading angular momentum. Using the simulation system, since the unloading angular momentum rate is maximized, the shape of the three-dimensional solar sail was optimized using a Genetic algorithm and Sequential Quadratic Programming. The unloading velocity in the optimized shaped solar sail was greatly improved with respect to a conventional flat or pyramid solar sail.

卫星太阳帆膜的形状对于在三轴稳定姿态控制系统中卸载角动量至关重要，因为三维太阳帆可以接收来自任意方向的太阳辐射压力。在本文中，目标是使用角动量卸载策略优化三维膜结构的太阳帆的形状。我们为卸载角动量建模并模拟了太阳辐射压力扭矩。使用仿真系统，由于最大卸载角动量速率，因此使用遗传算法和顺序二次规划对三维太阳帆的形状进行了优化。相对于常规的扁平或金字塔形太阳帆，在优化形状的太阳帆中的卸载速度得到了极大的提高。
