The solicitation request is for a structural and mechanical innovation, with a deliverable of an elevated Lunar Surface Solar Array design capable of delivering 50kW of power. We propose modifying and integrating Folditures proprietary Pyramid Hinge Array design, with novel linear extension mechanisms, as a solution for a large scale re-deployable Lunar Surface Solar Array Structure - Sunflake Extra Linear Array (Sunflake XL). Combined with a modified UCTT base, the design would deliver a disruptively compact, robust structure for Lunar Solar Power Generation. The design is scalable, modular, and can be integrated for transport/deployment with a lunar rover. In contrast, traditional designs require heavy structural support, and complex locking mechanisms. These are weak points prone to failure, that add substantial weight and volume, pack inefficiently, and are mostly not retractable. In Phase I we propose to fully develop a working mechanical design for the array structure, while applying the best available technologies. The design will be proven through a detailed 3D model, calculations, and physical models of specific details. This work will be the foundation for prototyping in Phase II. Anticipated
Benefits: The Sunflake XL could be used on any Human Lander, or future Lunar Outpost. It could be modified for other Planetary missions, and can also be deployed on Orbit Stations or Satellites. Sunflake XL is designed for multiple actuations. It can also be easily modified for spring-loaded single actuation. Because of its light mass, and proven Pyramid Hinge reliability, it could prove effective on mid to large scale satellite missions. Any other current of future missions that require lightweight portable high efficiency PV energy could be of interest. A modified Sunflake XL array, could be used in a variety of terrestrial applications. It would make an extremely compact and portable design. A stand-alone system could be deployed, programmed to track sun angles, and retract remotely. We are exploring DOD and other applications for remotely re-deployable pop-up PV power generation, suitable for challenging terrain.
