To meet NASArsquo;s need for compact, low-cost and autonomous deployable solar array systems to support near-term Lunar and future Martian exploration objectives, Roccor proposes to continue developing thenbsp; Articulating Solar Panel Energy (ASPEN) system by replacing the z-folded membrane PV blanket baselined for use in the CTSA architecture with an array of discrete modular thin-substrate solar panels supported by cables to enable panel articulation in unison much like ldquo;Venetian blindrdquo; blades. Significant advantages of articulated PV panels include more efficient power generation, lower procurement costs, and reduced mass and stowed volume.The ASPEN array technology is compatible with all central-column-tensioned-membrane solar array architectures including Lockheedrsquo;s Flexible Substrate Solar Array (FSSA), Roccorrsquo;s Flexible Substrate Resilient Array (FSRA), and NASArsquo;s CTA/CTSA.nbsp; Key improvements and advantages of the proposed Phase II ASPEN technology include:Discretization of the membrane blanket into an array of panels to simplify and reduce manufacturing costs, allow individual panel replacement, upgrades, or system expansion.Decoupling load bearing tension elements from the solar cell substrate enables use of less massive tensioning cables and mechanisms, and ability to tailor tension to achieve desired deployed stiffness.Panel louvering offers a second solar panel articulating axis, in addition to axial, which can potentially improve sun tracking for lunar, Martian, or zero-G satellite applications.The ability to louver the panels perpendicular to the mast enables simplistic and autonomous retractability.Roccorrsquo;s proposed Phase II program would deliver a sub-scale engineering demonstration unit of the ASPEN technology for application to both lunar and Martian surface operations.
