Low temperature (550 C) SOFC will be developed and characterized with a combination of impedance spectroscopy and high resolution microscopy (FIB, SEM, TEM, XEDS, EELS, SAED, CBED methods). Initial focus will be on a low temperature samarium doped ceria electrolyte and low temperature cathodes to include LSCuF, LSCoF-SDC, LSCuF-SDC, and SmSrCo-SDC. Key interfacial structure and aging effects wil ...

Compared to conventional power sources, fuel cell systems present such benefits as high efficiency, low emissions, long life, and near silent operation. Of the various fuel cell types, Solid oxide Fuel Cells (SOFC) have a number of advantages in hydrocarbon fuel applications because of their solid-state construction and high temperature operation. Presently, SOFCs operate in the temperature range ...

Soar Technology proposes to improve the efficacy of existing combat simulations by introducing a more realistic computer-generated adversary (OPFOR). To do this, we introduce GAMBIT - a novel system for dynamically generating and implementing asymmetric tactics supported by the use of genetic algorithms. Using GAMBIT, asymmetric tactics are generated offline given the initial conditions of a scena ...

Battery prognostic solutions tend to be tailored to the specific chemistry and application with years of characterization testing to fit the battery models to the actual battery performance. The effort laid out in this proposal is a collaboration between Qualtech Systems, Inc. (QSI) and the Energy Storage Testing Laboratories at the Idaho National Laboratories (INL). The proposed solution is a com ...

Preliminary development of a noise audit model for vector sensor towed arrays will be performed and is focused on tasks related to validating an analytical model of a thin-line array. An in-house numerical code known as the duct transmission line (DTL) modeling tool will be adapted for specific application to towed arrays having periodic impedance discontinuities. Flow noise mitigation technique ...

Current ASW missions require low frequency off-board sound sources that can operate monostatically or bistatically. Since these sources may or may not be recoverable, and may require a substantial number to cover the designated operating areas, the low frequency source transducers also need to be low cost. The team of Etrema Products and Applied Research Laboratory at The Pennsylvania State Univ ...

Heated plumes in a crossflow produce a thermal infrared signature and can impinge on temperature-sensitive systems downstream; both factors can degrade the performance and survivability of military assets. No validated code exists that can model heated jets from non-circular nozzles in a crossflow. Current CFD solutions are problematic due to the numerous expert modeling choices that they require. ...

The capability to deploy, maintain, and retrieve a network of small unmanned underwater vehicles from an unmanned surface craft is a vital missing link for the Navy as it increases its reliance on unmanned vehicles for littoral, minesweeping and other operations. To this end, Michigan Aerospace Corporation, in partnership with the University of Kentucky, proposes to develop a fully-autonomous depl ...

Steel and aluminum plates can be joined to PMC plates using patented Dynamic Polymer Composite (DPC) techniques. Dynamic Joining begins with an edge-weldment to a metal plate. This edge is then dynamically mated to a super-plasticized strip of a composite panel. Adhesive plays a minor role. The result is a lap-joint more capable of tension, moment, shear, and impact than any hand lay-up. Analysis ...

In this proposal ThermoAnalytics and Clemson University have jointly proposed to develop a modeling capability for two phase electronics cooling that would use the commercial thermal analysis package MuSES as a framework. Three high level tasks are defined in the work plan. In Task 1 component models for a microchannel heat sink and a spray cooling device will be developed. These will be drawn ...
