SELF-RIGIDIZING EXPANDABLE-SANDWICH AEROSPACE SHELTERS AND SOLAR COLLECTORS.
ARCHER DANIELS MIDLAND CO MINNEAPOLIS MINN
The objectives of the program are 1 fabrication, space deployment, and rigidification of a large parabolic solar collector 2 fabrication and space deployment of inflatable, rigidizable space shelter structures. The first 10-foot diameter mirror was completed by addition of the plumbing attachments to the manifold for the rigidization task. However, due to some slight leakage between the inflated sandwich and mirror shell coat, it was decided that this unit will be rigidized in ambient conditions. The 4-foot diameter x 8-foot long cylinder was completed, including impregnation. However, deployment in the vacuum chamber was unsuccessful because the resin had already rigidified.
