Large spaceborne antenna reflectors using inflatable space rigidized structures
Abstract
Center and offset fed reflectors for space applications were studied. Stiffness and temperature distribution of scale models of a 10 m inflatable reflector were examined. A feasibility study of a 20 m reflector for the QUASAT very long baseline interferometry mission was performed. A manufacturing concept for a large offset antenna was developed. The studies indicate that large inflatable antennas with good performance, high stiffness (3.17 Hz lowest frequency at 20 m aperture) and thermal stability (0.4 mm rms worst case at 20 m aperture) are feasible. Manufacturing accuracy and packaging efficiency can be achieved at low cost.
