The present disclosure relates to deployable structures, methods and apparatus for deploying deployable structures, and associated manufacturing methods. Such deployable structures suitably include components for spatial structures, such as supports for solar arrays, antennas, or other similar systems. The deployable structure includes grid elements arrangeable in a stowed configuration and a deployed configuration. The grid element (200) comprises: prestressed strips (306, Figure 3a) arranged in a clockwise helix; a pre-stressed strip (308, Figure 3a) arranged in a counter-clockwise helix; and a plurality of fasteners (310, Fig. 3a) for rotatably coupling the strips to each other at a plurality of locations distributed along the length of the strips. The plurality of fasteners are disposed at unequal pitches along the length of the strip such that the grid elements, when deployed, bend into a curvilinear deployed configuration.

    本公开涉及可展开结构、用于展开可展开结构的方法和设备以及相关联的制造方法。这样的可展开结构适当地包括用于空间结构的部件,诸如用于太阳能阵列、天线或其它类似系统的支撑件。所述可展开结构包括可布置成处于收起配置和展开配置的栅格元件。所述栅格元件(200)包括:以顺时针螺旋布置的预应力条带(306,图3a);以逆时针螺旋布置的预应力条带(308,图3a);以及多个紧固件(310,图3a),用于在沿所述条带的长度分布的多个位置处将所述条带可旋转地彼此联接。所述多个紧固件沿所述条带的长度以不相等的间距设置,使得所述栅格元件在展开时,弯曲成曲线的展开配置。
