阅读说明：本技术 一种离轨帆展开方法及其装置 (Off-rail sail unfolding method and device ) 是由 李晓明 王战辉 邹宇 任维佳 于 2019-11-29 设计创作，主要内容包括：一种离轨帆展开方法及其装置,包括非折叠帆(200)和折叠帆(300),非折叠帆(200)与折叠帆(300)可转动连接以形成驱使星体(100)离轨的离轨帆；折叠帆(300)包括能够在其呈折叠状态时用于折叠帆体的且在其呈展开状态用于支撑帆体的至少一个第一骨架(300a),在折叠帆(300)相对非折叠帆(200)的第一侧边转动至折叠帆(300)与非折叠帆(200)的第一夹角(α)为第一临界值的情况下,至少一个第一骨架(300a)中的一个或多个按照其能够与第一侧边并行的方式开始绕折叠帆(300)转动,并且折叠帆(300)相对非折叠帆(200)的第一侧边继续转动,从而第一夹角(α)继续增大至能够使得折叠帆(300)与非折叠帆(200)形成离轨帆的第二临界值。在发射前,折叠帆(300)就能够折叠好,以尽量减小体积；离轨帆展开状态下有足够大的面质比。(An off-orbit sail unfolding method and an off-orbit sail unfolding device comprise an unfolded sail (200) and a folded sail (300), wherein the unfolded sail (200) and the folded sail (300) are rotatably connected to form the off-orbit sail for driving a star body (100) to be off-orbit; the folded sail (300) comprises at least one first skeleton (300a) able to fold the sail body when it is in the folded state and to support the sail body when it is in the unfolded state, in the case where the folded sail (300) is rotated with respect to a first side of the unfolded sail (200) until a first angle (α) of the folded sail (300) with respect to the unfolded sail (200) is a first threshold, one or more of the at least one first skeleton (300a) starts to rotate around the folded sail (300) in such a way that it can be parallel to the first side, and the folded sail (300) continues to rotate with respect to the first side of the unfolded sail (200), so that the first angle (α) continues to increase to a second threshold enabling the folded sail (300) to form an off-track sail with respect to the unfolded sail (200). Before launching, the folding sail (300) can be folded to reduce the volume as much as possible; the surface-to-mass ratio of the off-rail sail in the unfolded state is large enough.)
