Deployable reflector
A reflector is provided according to various embodiments. The reflector may include a backing structure having various configurations. The backing structure, for example, can comprise a plurality of trusses, flexible couplings, stiffeners, and crossbeams in any number of arrangements.
1. A reflector comprising:
a reflector having a deployed configuration and a stowed configuration, wherein in the deployed configuration the reflector comprises a three dimensional geometry and in the stowed configuration the reflector comprises a plurality of pleats, wherein the reflector includes a front surface and a back surface;
a stiffener coupled with the back surface of the reflector; and
a backing structure coupled with stiffener, the backing structure comprising:
a plurality of rigid panels coupled with the stiffener such that in the stowed configuration each of the plurality of rigid panels is positioned within a valley of one of the reflector surface pleats; and
a plurality of crossbeams comprising a shape memory material and disposed between two of the plurality of rigid panels, wherein the plurality of cross beams form pleats in the stowed configuration.
2. The reflector according to claim 1 , wherein the stiffener comprises a plurality of stiffeners.
3. The reflector according to claim 1 , wherein the stiffener is not integral with the reflector.
4. The reflector according to claim 1 , wherein the backing structure comprises a plurality of trusses and the stiffener extends across a horizontal portion of the reflector in a substantially perpendicular orientation relative to the trusses.
5. The reflector according to claim 1 , wherein the stiffener is coupled with the back surface of the reflector at a plurality of discrete locations.
6. The reflector according to claim 1 , wherein the stiffener comprises a shape memory polymer.
7. The reflector according to claim 1 , wherein the stiffener comprises a plurality of stiffeners coupled with the back surface of the reflector and the backing structure.
8. A deployable reflector system with a backing structure comprising:
a reflector having a deployed configuration and a stowed configuration, wherein in the deployed configuration the reflector comprises a shape, and in the stowed configuration the reflector comprises a plurality of pleats, wherein the reflector includes a front surface and a back surface;
a plurality of stiffeners coupled with the back surface of the reflector; and
a backing structure comprising:
a plurality of trusses, wherein at least one of the plurality of trusses is coupled with at least one of the plurality of stiffeners;
