Structures used in space applications demand the highest levels of stiffness for their mass whilst also performing in a hostile environment. To partly address these requirements and so as to also pack efficiently for stowage during launch we propose a new type of compact telescopic morphing lattice space boom. This boom stows within a 1U CubeSat volume and is lightweight being only 0.4 kg. The boom has a total length of 2 m in its deployed state which is 20 times its stowed height. The device comprises two multi-stable cylindrical composite lattices that are joined telescopically. These lattices nest inside one another in the stowed configuration, with the objective of improving packaging efficiency. Notably, prestress and lamina orientation are used to smoothly change shape from being compact when stowed to being extended when deployed. The lattices in the boom have been designed to maximise deployment force and to be self-deploying by tuning manufacturing parameters. As a result, only a small, lightweight mechanism is required to regulate deployment speed of the lattice boom. By reversing its direction, this mechanism can be used to retract the lattice boom to its stowed configuration, thereby enabling two-way reconfigurability.

在太空应用中使用的结构要求其质量具有最高水平的刚度，同时还要在恶劣的环境中工作。为了部分满足这些要求，并在发射过程中有效地收起行李，我们提出了一种新型的紧凑型伸缩变形格形空间吊杆。该动臂收起的体积为1U CubeSat，重量仅为0.4千克，重量轻。动臂在展开状态下的总长度为2 m，是其收起高度的20倍。该装置包括两个可伸缩连接的多稳态圆柱形复合格子。这些格子以收纳构造彼此嵌套在内部，目的是提高包装效率。值得注意的是，预应力和薄板取向用于将形状从收起时的紧凑形状转变为展开时的伸展形状。动臂中的格栅经过设计，可以最大程度地发挥展开力，并可以通过调整制造参数进行自我部署。结果，仅需要小型，轻便的机构来调节桁架的展开速度。通过反转方向，该机构可用于将桁架臂缩回至其收起状态，从而实现双向可重构性。
