Pathfinder Photogrammetry Research for Ultra-Lightweight and Inflatable Space Structures

The defining characteristic of ultra-lightweight and inflatable space structures is that they are both very large and very low mass. This makes standard contacting methods of measurement (e.g. attaching accelerometers) impractical because the dynamics of the structure would be changed by the mass of the contacting instrument. Optical measurements are therefore more appropriate. Photogrammetry i...

Inflatable Tubular Structures Rigidized With Foams

NASA Tech Briefs, March 2010 Inflatable tubular structures that have annular cross sections rigidized with foams, and the means of erecting such structures in the field, are undergoing development. Although the development effort has focused on lightweight structural booms to be transported in compact form and deployed in outer space, the principles of design and fabrication are also potentiall...

Toward Rigidization of Inflatable Structures

Active rigidization of a simple structure demonstrates how internal resistive heating can be applied to cause permanent physical strengthening of inflatable structures. Rigidizing a real structure brings to light the issues associated with incorporating the rigidizable resincoated tow onto a separate substrate and provides a useful example of the strength gained through effective rigidization. ...

Deployment Simulation of Ultra-lightweight Inflatable Structures

Dynamic deployment analyses of folded inflatable tubes are conducted to investigate modeling issues related to the deployment of solar sail booms. The analyses are necessary because ground tests include gravity effects and may poorly represent deployment in space. A control volume approach, available in the LS-DYNA nonlinear dynamic finite element code, and the ideal gas law are used to simulat...

Initial performance assessment of hybrid inflatable structures

Inflatable technology for space applications is under continual development and advances in high strength fibers and rigidizable materials have pushed the limitations of these structures. This has lead to their application in deploying large-aperture antennas, reflectors and solar sails. However, many significant advantages can be achieved by combining inflatable structures with structural stif...
