充气空间结构有可能大大减少空间探索任务所需的大型载人压力容器的发射体积。通过使用高比强度的纺织品材料，还可以节省质量，并减少在密集包装状态下发射结构的设计损失。自20世纪50年代后期以来，人们一直在研究可充气纺织品结构，NASA和工业界的几个主要开发项目有助于推进该技术领域的最新技术。本文讨论了充气纺织品结构的设计、分析、结构试验和潜在应用。特别是，本文将讨论多层纺织品外壳（内层、气囊、结构约束层、微流星体轨道碎片保护层、隔热层和原子氧层（用于低地球轨道））的设计以及美国航天局过去二十年来进行的材料和模块一级测试的结果。最后，目前利用可扩展的航天器结构进行了讨论，以及潜在的未来应用，包括气闸和栖息地的月球轨道平台网关，月球和火星的表面。
Inflatable space structures have the potential to significantly reduce the required launch volume of large crewed pressure vessels for space exploration missions. Mass savings can also be achieved via the use of high specific strength softgoods materials, and the reduced design penalty from launching the structure in a densely packaged state. Inflatable softgoods structures have been investigated since the late 1950’s, and several major development programs at NASA and in industry have helped advance the state-of-the-art in this technology area. This paper discusses the design, analysis, structural testing, and potential applications for inflatable softgoods structures. In particular, this paper will discuss the design of the multi-layer softgoods shell (inner layer, bladder, structural restraint layer, micrometeoroid orbital debris protection layers, thermal insulation layers, and atomic oxygen layer (for low earth orbit) and the results of material and module-level testing that has been conducted over the past two decades at NASA. Finally, the current utilization of expandable spacecraft structures is discussed, as well as potential future applications including airlocks and habitats on the Lunar Orbital Platform-Gateway, and the surface of the Moon and Mars.
