The invention discloses an integrated foldable truss structure with the length of hundreds of kilometers, the integrated foldable truss structure with the length of hundreds of kilometers is overturned in multiple directions, one-dimensional unfolding in the length direction is finally achieved, and the length can reach hundreds of kilometers after unfolding; the integrated foldable truss structure with the length of hundreds of kilometers comprises a plurality of truss units, a plurality of connecting mechanisms and a plurality of locking and damping mechanisms, the foldable truss units are arranged in the rocket fairing in a stacked mode in the radial direction and the circumferential direction in a multi-row and multi-column neat arrangement mode or in a multi-row and multi-column non-neat arrangement mode. Each truss unit is composed of a plurality of truss subunits which can be unfolded in the length direction; the folding efficiency in the direction perpendicular to the radial direction of the rocket fairing is high, the smaller space of the rocket fairing can be fully utilized to achieve the higher folding ratio, and meanwhile after the rocket fairing is unfolded in the radial direction of the rocket, the integrated foldable truss structure with the length of hundreds of kilometers and the ideal working state can be rapidly achieved.

    本发明公开了一种长度百千米级一体化可折展桁架结构,该长度百千米级一体化可折展桁架结构通过多个方向的翻转,最终实现长度方向的一维展开,展开后长度能够达到百千米;该长度百千米级一体化可折展桁架结构包括多个桁架单元、多个连接机构、多个锁定和阻尼机构;该多个可折叠桁架单元沿着径向和周向,成多行多列整齐排列或成多行多列非整齐排列的堆叠状布设在火箭整流罩中;每个桁架单元由多个沿着长度方向可展的桁架子单元组成;本发明在垂直于火箭整流罩的径向方向的折叠的效率较高,能够充分利用火箭整流罩的较小的空间内实现更高的折叠比,同时在沿着火箭的径向展开后能够迅速达到长度百千米级一体化可折展桁架结构和理想的工作状态。
