TLDR
In this paper, a method for stowing a unitary flexible antenna reflector 10 in a confining envelope and deploying the reflector from the envelope is described, which includes the steps of: a) applying a deforming force to diametrically opposed positions 16 and 18 near an edge of a reflector, b) maintaining the reflected object in a deformed state until deployment, and c) releasing the reflectored object from the deformed position.Abstract:
A method for stowing a unitary flexible antenna reflector 10 in a confining envelope and deploying the reflector from the envelope. In a most general sense, the invention includes the steps of: a) applying a deforming force to diametrically opposed positions 16 and 18 near an edge of the reflector 10 to place the reflector in a deformed state; b) maintaining the reflector 10 in the deformed state until deployment; and c) releasing the reflector 10 from the deformed state. In a specific embodiment, the step of maintaining the reflector 10 in a deformed state includes the step of attaching a restraining element between the diametrically opposed positions on the edge of the reflector which is released on deployment.read more

Deployable structures classification: A review:
GE Fenci,Neil G. R Currie +1 more
TL;DR: A critical review of existing attempts at classifying deployable structures identifying connections between different families through their mechanical and structural behaviours concludes that a clear, comprehensive, consistent and unified classification of deployable structure is currently missing within the field.

High Strain Composites
TL;DR: High strain composites as discussed by the authors is a field of research that encompasses structures that undergo large deformations through composite materials capable of large strains, such as carbon fibers and composites with relatively stiff matrix materials and soft or softenable matrix materials.

Spacecraft antenna reflectors and stowage and restraint system therefore
George T. Hayes,Louise B. Brydon +1 more
TL;DR: In this article, a dual-band reflector is attached to a spacecraft body for deployment between a stowage position in which it is pivoted and restrained up against a face of the spacecraft body and the flexible annular reflector areas partially flexed there around.

Self-deployable solar cell panel
TL;DR: In this article, a pair of semi-rigid solar cell panels are curved under stress and latched in arcuate edge abutting fashion about the exterior of a spacecraft body, and upon release of the latched ends flatten into tangency at opposite sides of the spacecraft body.

Folding dish reflector
TL;DR: In this paper, a folding parabolic reflector antenna for reception of microwave signals is proposed, which includes a single sheet of resiliently elastic reflecting mesh supported by a radial framework of normally straight resiliently flexible spokes of tapering cross section.

Deployable membrane shell reflector
TL;DR: In this paper, a flexible reflector shell is deployed by remote signal and formed an underlying structure upon which the reflector unrolls, and magnetic strips and auxiliary retaining mechanisms align and retain it on the underlying support and urge it to a position from which it can accurately reflect eletromagnetic radiation.
