The concept of passive surface error control via tension is explored for flexible square panels and for a rectangular array of such panels suspended with four catenaries. The panels are 1 mm thick 1 m square graphite-epoxy composite plates with a fou

Theoretically discussed and analytically compared are four structural paradigms for the isotropic stretching of circular membrane apertures with three-point tensioning of regular (120 deg) symmetry. These are 1) a film triangle with parabolic catenar

A low-cost rigid foam-based concentrator technology development program was funded by the DOE SunShot Initiative to meet installed cost goals of $75/m2 vs. current costs of ∼ $200–250/m2. Phase 1 of the project focused on design trades and cost a
