The manufacturing process for defense systems—from aircraft to vehicles to ships—is extremely complex and fragmented, often demanding unique materials and processes, complex certification requirements and specifications, and specialized tools and equipment. The almost inevitable result: lengthy production timelines and high costs. The manufacture of diverse small parts for military systems could be made simpler, faster, and less expensive with the development of a tailorable composite feedstock material and a single tailorable forming method.
DARPA published its Young Faculty Award (YFA) 2018 Research Announcement today, seeking proposals in 26 different topic areas—the largest number of YFA research areas ever solicited.
Manufacturing by assembly provides the flexibility to freely combine materials and components and is fundamental to creating devices from cell phones to appliances to airplanes. However, assembly processes are currently not practical at the nanoscale. The A2P program was conceived to deliver scalable technologies for assembly of nanometer- to micron-scale components—which frequently possess unique characteristics due to their small size—into larger, human-scale systems.
Certain natural processes perform par excellence computation with levels of efficiency unmatched by classical digital models. Levinthal’s Paradox illustrates this well: In nature, proteins fold spontaneously at short timescales (milliseconds) whereas no efficient solution exists for solving protein-folding problems using digital computing. The Nature as Computer (NAC) program proposes that in nature there is synergy between dynamics and physical constraints to accomplish effective computation with minimal resources.
The capabilities and technical specifications required for Department of Defense (DoD) platforms are constantly changing due to unanticipated circumstances, needs and emerging threats. However, complex development and design cycles and the associated high costs of structural design changes for current technologies significantly limit our ability to rapidly and affordably evolve such systems.
