Small Business Innovation Research Program (SBIR) Phase II

Sunflake Extra Linear

Combining our proprietary Pyramid Hinge Array, with other novel mechanical and geometric solutions, we propose a disruptively compact, robust structure for Lunar Solar Power Generation ndash; The Sunflake XL array, and Ultra Compact Quad Tower (UC4T) nbsp; Sunflake XL delivers a 175msup2; ultra compact Lunar Surface Solar Array, capable of delivering 50kW of power. The solar array raises up to 10 meters off the ground (achieving a total height of 17m). Sunflake XL rotates for optimal sun tracking, while the UC4T provides a stable vertical structure. nbsp; Combined together with the tower and rover-deployment system, the entire package will deliver a performance of 113 W/kg and 26 kW/m3. The system is ultra compact, lightweight, stable, and retractable. nbsp; Most important, it is based on our proven pyramid hinge technology, making it a reliable and robust solution. The novel design combines the strength, compactness, and durability of the Pyramid Hinge, with linear expanding array elements, adding a new dimension of scalability to our Sunflake solutions. The novel mechanisms can also be re-configured for different deployable solutions: antennas, reflectors, or radiators. nbsp; With a linear arm segment measuring only 2.6 m, the new design opens a new spectrum of opportunities for pyramid-hinge based designs. nbsp; In Phase I Folditure validated the design, packing efficiency, scalability, and retractability of the mechanism, through detailed mechanical drawings, analysis, and a functional prototype. nbsp; In Phase II we propose to fully develop the kinematics and structure. We plan to engineer, and build a very large-scale high fidelity kinematic prototype, while further developing, and applying the best available technologies. The design will be also proven through FEM analyses, and environmental testing. We also propose to field test the prototype deployment, with anbsp;lunar rover. This project is very well aligned with our area of expertise: developing super-compact novel folding solutions.

The goal of phase II is to continue the R&D efforts initiated in Phase I. Funding is based on the results achieved in Phase I and the scientific and technical merit and commercial potential of the project proposed in Phase II.
