ABSTRACT: IRradiance Glass, Inc. proposes a Phase I STTR program in conjunction with the University of Central Florida to demonstrate the feasibility of the design, development, and production of high numerical aperture (NA) cylindrical lenses for use in the mid- to long-wave infrared optical region by extruding chalcogenide glasses into a micro-lens shape (~2mm wide x 2 mm high x 3 mm long) with ...

ABSTRACT: The rapid continued development of unmanned air systems (UAS) is enabling new mission types, in-creased mission effects, and increased airman safety. However, these advances also present numerous challenges to airman-machine interaction, tactics development, and defense. The rapid development pace has produced a situation where new technologies are outpacing the knowledge of how best to ...

Ultra-high-performance concrete (UHPC) offers superior properties for structural applications. Existing UHPC design and production methods employ special materials and mixers. This project is developing mix design and fabrication methods for reliable production of UHPC with local materials and facilities. The Phase I project devised material selection criteria, proportioning methods and mixing pro ...

ABSTRACT: Information systems continue to progress in terms of collecting, characterizing and assessing information. While this evolution has provided unprecedented intelligence capability to the U.S. and our allies, it has also raised unique challenges in the area of information security and disclosure risks. In particular, the intelligence community (IC) currently lacks the ability to understand ...

ABSTRACT: Energetic composite materials comprise crystalline energetic particles embedded in a polymer matrix. There is a need to gain insight into the microstructure and damage mechanisms of energetic composites via nondestructive evaluation. Applications of x-ray computed micro-tomography to resolve the microstructure of energetic composites are challenged by the low density gradient between th ...

ABSTRACT: To unlock the power of cooperating teams of autonomous cyber-physical systems (CPSs), humans must be able to effectively, reliably, and safely task them using high-level goals. SIFTs Playbook interface approach provides goal-based tasking for multi-agent autonomous missions. SIFTs Cooperative Intelligent Real-time Control Architecture (CIRCA) automatically synthesizes and verifies r ...

ABSTRACT: Designing propulsion devices and munitions for precise operational performance demands control and manipulation of energy released by explosive materials. It is well recognized that the initiation of energetic materials in explosives applications depends sensitively on hot-spots that originate from various heterogeneities at the meso (particle)-scale such as voids, defects, dislocations ...

ABSTRACT: The next generation of hypersonic and reentry vehicles being designed for the Department of Defense (DoD) applications will require advanced Thermal Protection System (TPS). While new TPS shields are under development, a key difficulty is the ability to predict and diagnose TPS performance. ElectroDynamic Applications (EDA) has been developing an optical diagnosticfor use during testi ...

ABSTRACT: The proposed Phase I efforts seek to develop a dual-mode Hybrid ChemicalElectric Propulsion thruster concept design based on the extensive microwave torch/arcjet experience of PSU and Hall and ion experience of EDA. The primary focus of the Phase I effort will be demonstrate the operation of an ionic liquid microwave thruster in the high-T/P regime and the basic operation of a Hall and ...

ABSTRACT: Under this collaborative effort between A Brown Design, Michigan State University, and Raytheon, a novel phase shifter design is proposed. The phase shifter design builds upon existing RF MEMS capacitive technology by co-integrating MEMS switches with metamaterial unit cells. The metamterial unit cell design is versatile and allows significant degree of freedom in integration and design ...
