Thin-film solar reflectors and methods |
摘要 |
Flexible, lightweight reflective sheets are positioned to concentrate solar radiation upon spacecraft solar panels. The sheets are positioned with inner and outer spring members which urge each sheet towards a planar configuration and further urge the sheet in a rotation away from a solar panel face. Restraint members in the form of tethers limit this rotation to place the sheet in a deployed position in which it defines an angle with the panel to reflect solar radiation onto the panel face. The increased incident radiation permits a reduction of the number of solar cells with consequent savings in spacecraft cost and weight. The spring members are configured to permit rotation to a stowed position behind the solar panel. In this position, the tethers are received into guides which are configured to initiate automatic deployment of the spring members and their reflective sheets.
