초록 ▼

The application of technically sensitive devices in outer space requires adequate protective shields or protective chambers which protect the payload against atmospheric radiation, thermal effects etc. The foldable structure according to the invention consists of a topological arrangement of flexible tubes which are joined to each other and form the skeleton of the shield or of the chamber. To these tubes there are attached membranes which serve as protective walls. The method of manufacturing a finished protective device uses such a foldable structure, whereby the structure is unfolded by inflation of the tubes and assumes the desired two-dimensional or three-dimensional form. The membranes are also stretched by the extension of the tubes and the interaction of the membranes and the tubes, such tubes acting as struts in the inflated condition, produces a stable structure. The foldable structure according to the invention and the method of manufacturing render possible that devices having dimensions of and more meters can be easily erected with high reliability. Since the structure in the unfolded condition is stabilized by the tubes, non-closed surfaces or protective chambers comprising hatches can also be manufactured in contrast to balloon-type bodies known so far.
