航空航天公司的 DARPA-航空航天 PICOSAT 项目将在短期内部署薄膜太阳能电池阵列作为其小型卫星的电源。该阵列的部署机制是独特的，因为由于可用空间极其有限，它无法使用传统的吊杆、铰链、闩锁或挡块。为了以最紧凑的方式装载薄膜太阳能电池阵列，建议使用由极其柔韧的金属制成的挠性铰链。在本文中，超弹性钛镍合金在结构、铰链和展开能量装置中的先前使用被扩展为包括将展开结构锁定到位的闩锁的功能以及将电流从电池带回卫星的电气总线。通过用单个元件执行所有这些功能，可以降低阵列的复杂性和成本，简化组装过程并提高可靠性。
The Aerospace Corporation's DARPA-Aerospace PICOSAT project will, in the near term, deploy a thin-film solar array as a power source for its small satellite. The deployment mechanism for the array is unique because it cannot employ conventional booms, hinges, latches, or stops, due to the extremely limited room available. In order to stow thin-film solar cell arrays in the most compact manner, a flexure hinge made of an extremely flexible metal has been suggested. In this paper, the prior use of the superelastic Ti-Ni alloy for the structure, hinge and unfolding energy device, is extended to include the function of a latch that locks the deployed structure in place and the electrical bus which carries current from the cells back to the satellite. By performing all these functions with a single element, the complexity and cost of the array is reduced, the assembly process is simplified and the reliability increased.
