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: 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: Ultra-high performance concrete (UHPC) materials with outstanding material properties offer significant promise to transform infrastructure design and service life. Evolution of UHPC into a mainstream construction material would benefit from the resolution of issues relevant to the restrictive selections of finer aggregates/fillers, large heat of hydration and thermal stresses, high aut ...

ABSTRACT: In this Phase I STTR project, we propose to demonstrate the feasibility of developing a low cost, compact, time-domain terahertz (TD-THz) spectrometer specifically for the characterization of semiconductor materials over a range of temperatures, electric fields, and magnetic fields. In phase I, we will configure fiber optic coupled TD-THz instrumentation to make measurements on a sampl ...

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 ...

ABSTRACT: Michigan Aerospace Corporation, in cooperation with the University of Michigan"s Department of Atmospheric, Oceanic, and Space Sciences, will refine existing upper atmospheric models and apply them to the problem of predicting satellite drag. The primary goal of this Phase 1 project is to run a fully validated version of University of Michigan"s Global Ionosphere Thermosphere Model (GI ...

ABSTRACT: We will design, fabricate and test a quantum processing unit (QPU) based on a symmetric ion trap chip. The trap will provide trapping depth similar to that obtain with macrosize Paul traps. In addition to the ion trap, this chip will incorporate integrated optical systems which will deliver the light fields required by the elementary quantum processing unit (or quantum sensing unit). ...
