Innovators at NASA’s Johnson Space Center (JSC) have developed simulation software for predicting and analyzing loads and elongations of elements of the load-bearing layer of an inflatable structure or module. This layer is typically composed of straps of high-strength material such as Kevlar® brand fiber or Vectran® liquid crystal polymer fiber. Because these straps exhibit non-linear behavior under load, analysis is complex, especially when there are rigid pass-throughs (doors, windows, fluid ports, hatches, connecting tunnels) incorporated into the inflatable structure. This innovation allows accurate analysis and design of the straps that connect to the rigid pass-throughs. JSC has applied for patent protection for this technology.
