Abstract

This paper investigates the heliocentric time-optimal rendezvous performance of Sun-facing diffractive solar sails with various deflection angles and acceleration capabilities. Diffractive solar sails, which generate tangential radiation pressure force, are proposed and schematically designed to achieve diverse radiation pressure distributions. The radiation pressure force model and the time-optimal control problem for these innovative Sun-facing diffractive solar sails are established. Utilizing an indirect method and the optimal control law, we explore typical heliocentric rendezvous scenarios to assess the variational trends of transfer time in relation to different deflection angles and acceleration capabilities. The results for Sun-facing diffractive sails in specific rendezvous missions are compared to reflective sails with the same area-to-mass ratio, focusing on transfer trajectory and attitude control. Our findings reveal that diffractive sails exhibit significant advantages over reflective sails, particularly in the context of normal acceleration, paving the way for more efficient space exploration.

具有不同偏转角的面向太阳的衍射太阳帆的最短会合时间

本文研究了具有不同偏转角度和加速能力的面向太阳的衍射太阳帆的日心时间最佳交会性能。衍射太阳帆产生切向辐射压力力，本文提出了衍射太阳帆的设计方案，以实现不同的辐射压力分布。为这些创新的面向太阳的衍射太阳帆建立了辐射压力力模型和时间最优控制问题。利用间接方法和最优控制法则，我们探索了典型的日心交会场景，以评估与不同偏转角度和加速能力相关的转移时间的变化趋势。我们将特定交会任务中面向太阳的衍射帆与具有相同面积质量比的反射帆的结果进行了比较，重点关注转移轨迹和姿态控制。我们的研究结果表明，与反射帆相比，衍射帆具有显著优势，尤其是在正常加速度方面，这为更高效的太空探索铺平了道路。
