The objective of the proposed research is to use chemistry to modify single-walled carbon nanotubes (SWNTs) and engineer the interfacial interaction with polymers to synthesize composite materials with enhanced mechanical, electrical and thermal properties. We will conduct research on the synthesis and properties characterization of SWNT-reinforced composites based on epoxies and vinyl esters. Our ...

This proposal is a joint effort between Qualtech Systems, Incorporated (QSI), the Institute for Software Integrated Systems at Vanderbilt University (VU), and Hamilton Sundstrand (HS) in Rockford, IL. QSI and VU have the combined knowledge and experience in successful development of a novel solution to aircraft system and subsystem prognostics and maintenance tools and have developed state-of-the- ...

The objective of this project is to develop an integrated condition monitoring, fault diagnostics and prognostics scheme for power electronic converters and electromechanical devices, e.g., advanced induction motors, specifically targeting the DD(X) platform and subsequently expanding the scope for addressing the needs of other defense-related and commercial applications. An additional goal of th ...

Hemp-based clothing are excellent for outdoor active wear, due to high strength, UV-protective qualities, mold resistance, and excellent moisture absorption and desorption. While academic research on hemp-based textiles in the US is increasing, it has naturally also become an area of interest to competing countries. Specifically, China is outperforming the US in hemp fiber technological advanceme ...

Hepburn and Sons LLC proposes to design a ground fault detection system for 440VAC three phase radial Navy shipboard power distribution, while teaming with their partner Florida State University, Center for Advanced Power Systems (FSU CAPS). Existing Navy ground fault detection systems can detect and locate single line to ground faults on a given phase, but a second ground fault on a separate phas ...

Both acoustic and electromagnetic waves exert forces of radiation on targets in their path of propagation. The radiation force (pressure) results from the change in wave momentum due to scattering by the target, averaged over one period of oscillation.  Modulated radiation pressure (MRP) utilizes the acoustic radiation force by using a double-sided suppressed carrier modulated (DSB-SCM) incident ...

High power semiconductor devices suffer from difficulty in dissipating heat and thermal stresses. Silicon carbide-based power modules, in particular, have increasingly challenging heat loads despite their high efficiencies. In general terms, the module packaging methods used to improve cooling (moving metal heatsinks closer to the die) also increase thermal stresses, and the methods used to reduce ...

Light absorption by aerosols is a key component to atmospheric extinction, and affects a number of processes relevant to the Navy. Satellite and other remotely sensed measurements can be strongly impacted by aerosols, obscuring targets and/or confounding interpretation of data products. Directed energy applications, including weapon and communication systems, are also impacted by absorption, which ...

MARi, LLC and Carnegie Mellon University are partnering to combine state of the art multimedia content tagging algorithms together with granular levels of task and Sailor analytics to ensure that knowledge objects can quickly move through a semi-automated, custom approval pathway - getting the latest and best information to the right person at the right time.  Knowledge sharing systems designed f ...

Hepburn and Sons LLC teamed with North Carolina State University (NCSU) proposes an analysis of alternatives (AoA) to design and optimize a megawatt class, solid state transformer rectifier (SSTR) supporting maintainability of U.S. Navy shipboard power infrastructure. The design will convert 13.8kV AC to +-850V DC with modular, line-replaceable units (LRUs) that are compact and lightweight such th ...
