Brief Description of Problem: Pharmacovigilance is a key area required for effective Force Health Protection. While good efforts have been made to address this problem, the traditional systems approaches used do not address underlying challenges such as data quality, unavailability and non-integration, and the expensive person-driven approaches to data mapping and integration inherent in traditi ...

There is a great need of gas turbine engines providing reduced specific fuel consumption (SFC), lower production and maintenance cost, and higher power to weight ratio. Innovative gas path seals are required to meet these goals and improve performance. Traditionally labyrinth seals have been used at various locations including at the hot turbine section of the engine. Significant amount of researc ...

This development work will explore innovative technologies to be added to textile fibers or fabrics used on the combat uniforms for the purpose of combat identification. The proprietary material will be designed to work over all frequency ranges from UV to beyond the 12 micron range. This work will investigate technologies that will allow materials to be instantly and intelligently recognized as ...

The project focuses on the development of an electrochemical variable buoyancy device for autonomous underwater vehicles. The approach is based on the electrochemistry of metal-gas batteries, wherein one electrode has a gaseous reactant and the other is a metal or metal oxide. The proposed electrochemical couple is metal hydride - hydrogen, which combines the metal hydride electrode of nickel meta ...

In response the U.S. Navy's desire to continuously improve its undersea weapons capabilities, Design By Analysis, Inc. of New Britain, Connecticut in conjunction with the University of Connecticut's Global Fuel Cell Center propose an auxiliary electrochemical power system for use in undersea weapon systems. This novel concept modifies an existing thermally propelled torpedo to include Proton Exch ...

An advanced vector hydrophone towed array is proposed for surface ship torpedo defense applications. Vector hydrophone promise to provide much-needed array gain in aperture-constrained systems. The additional gain results in significant increases in detection ranges and/or decreases in false alarm rates. A physics-based vector sensor array simulator will be developed in a modular architecture. ...

A critical design feature for a towed mine countermeasure platform is low drag. In this STTR we propose to integrate an efficient acoustic source within a low drag body to perform influence mine sweeps behind an unmanned surface vehicle. To develop the optimum system a trade-study is proposed during Phase I to examine electronically-powered transducers and novel hydroacoustic concepts. The tran ...

This project addresses the development of hybrid propulsion system technology for undersea weapons. The system will integrate a solid oxide fuel cell with a conventional engine or turbine. The proposed system is anticipated to have a superior range compared to conventional propulsion systems as the power for surveillance operations will be provided by a more efficient SOFC subsystem. The conven ...

Air Force seeks innovative permanent magnets for high temperature application in air and space vehicles. This requires the use of novel permanent magnets with high coercivity and saturation magnetization up to 450oC with an energy product of 30 MGOe. Inframat Corporation proposes to demonstrate the feasibility of fabricating an exchange-spring coupled Sm(Co,Fe,Cu,Zr)z/Co-Fe nanocomposite permanen ...

This program will develop a cost effective, highly repeatable process for fabricating spatially variable neutral density filters with very tight geometry. Three fabrication methods will be developed and evaluated. The first method consists of sputtering through a moving deposition mask. The mask is sheared relative to the part to achieve a rapid spatial change in optical density. The second method ...
