Abstract

A diffractive sail is a solar sail whose exposed surface is covered by an advanced diffractive metamaterial film with engineered optical properties. This study examines the optimal performance of a diffractive solar sail with a Sun-facing attitude in a typical orbit-to-orbit heliocentric transfer. A Sun-facing attitude, which can be passively maintained through the suitable design of the sail shape, is obtained when the sail nominal plane is perpendicular to the Sun–spacecraft line. Unlike an ideal reflective sail, a Sun-facing diffractive sail generates a large transverse thrust component that can be effectively exploited to change the orbital angular momentum. Using a recent thrust model, this study determines the optimal control law of a Sun-facing ideal diffractive sail and simulates the minimum transfer times for a set of interplanetary mission scenarios. It also quantifies the performance difference between Sun-facing diffractive sail and reflective sail. A case study presents the results of a potential mission to the asteroid 16 Psyche.

面向太阳的理想衍射帆的最佳行星际轨迹

衍射帆是一种太阳帆，其暴露的表面覆盖着一层具有工程光学特性的先进衍射超材料薄膜。本研究考察了在典型的轨道到轨道日心转移中，面向太阳姿态的衍射太阳帆的最佳性能。当风帆标称平面垂直于太阳-航天器直线时，可以通过适当设计风帆形状来被动保持对太阳的姿态。与理想的反射帆不同，面向太阳的衍射帆产生很大的横向推力，可以有效地利用它来改变轨道角动量。利用最新的推力模型，确定了面向太阳的理想衍射帆的最优控制律，并模拟了一组行星际任务场景下的最小传递时间。它还量化了面向太阳的衍射帆和反射帆的性能差异。一个案例研究展示了对小行星普赛克的潜在任务的结果。
