Thin-Shell Deployable Reflectors with Collapsible Stiffeners Part 1: Approach
Thin-shell deployable reflector structures that are folded elastically in a nearly inextensional mode have been recently realized, exploiting the recent availability of high-modulus, ultrathin composite materials. An inherent and significant limitation of this approach is that these structures remain “floppy” in their deployed configuration. This paper presents a general concept for increasing ...

Thin-shell deployable reflector structures that are folded elastically in a nearly-inextensional mode have been recently realized, exploiting the recent availability of high-modulus, ultra-thin composite materials.

متن کاملThin-Shell Deployable Reflectors with Collapsible Stiffeners: Experiments and Simulations
This paper presents an experimental and computational study of four deployable reflectors with collapsible edge stiffeners, to verify the differences in behavior that had been predicted in a previous theoretical study. The experimental models have different geometric configurations and are made of two different plastics. Both folding experiments and vibration tests in the fully deployed configu...
متن کاملDeployable Membrane Reflectors
This paper is concerned with the design of a new type of multi-purpose deployable membrane reflector. The reflector structure consists of a central expandable hub, a number of thin-walled foldable ribs connected radially to the hub, and a precision-shaped membrane supported and tensioned by the ribs. This concept is known as a collapsible rib-tensioned surface reflector. A methodology for the d...
متن کاملDeployable Reflectors for Small Satellites
A key limitation for future Small Satellite communications and radar missions will be available antenna reflector aperture. Two types of reflectors are dominant for satellite RF systems today, rigid, single-piece reflectors and deployable mesh reflectors. Single-piece reflectors are limited to the aperture that fits inside a launch vehicle without packaging the reflective surface. Mesh reflecto...
