Ruggedized Solar Panel for Use on a Kinetically Launched Satellite
Ruggedized solar panels for use on top of a satellite configured for a kinetic space launch are disclosed. The solar panels are able to maintain structural integrity and functionality of the solar cells under high acceleration forces generated during kinetic launch, including acceleration forces of >5,000 times Earth's gravity in a single direction of loading. The solar panels are ruggedized to withstand this level of acceleration force during launch via stiffening mechanisms, such as lamination of the solar panel into a sandwich panel structure, and/or use of support beams under a solar panel. Further, a high-specific-stiffness composition of the solar panel aids the solar panel in remaining flat during launch so it does not deflect inwards and damage the solar cells.
