Improved capacitor technologies are required for future power electronics and pulsed power systems being considered by the Navy as part of the All Electric Ship initiative. Using a single electrical generation system to supply power to both drive and auxiliary ship systems will enable much more efficient use of power, allow for damage tolerant distributed power systems, and provide high energy pu ...

High altitude airships (HAA) require regenerative fuel cell systems that can supply high current during nighttime operations with daily charging and discharging cycles for long periods of continuous operation. These fuel cells must be lighter in weight, and have higher charging and discharging efficiency while operating at high altitudes with no maintenance during operation for extended periods of ...

In this SBIR program Nanohmics propose to fabricate high breakdown strength flexible dielectrics films for use in high voltage capacitors from sputter deposited amorphous oxides. Previous work at Nanohmics has demonstrated a room temperature sputtering technique to deposit exceedingly high quality flexible amorphous nitride films at room temperature with properties similar to their single crystal ...

Stress-rupture life is a significant design issue for fiber reinforced composite pressure vessels subjected to long term pressurization. The considerable scatter in stress-rupture life exhibited by fiber reinforced composites, coupled with the lack of reliable life prediction methods, have led to the requirement for low operating pressures in relation to the design burst pressure. This leads to ...

Due to the inefficiencies associated with Directed Energy (DE) weapons, a large amount of waste heat is generated that must be removed quickly to maintain a constant temperature operation. To remove such a high heat flux, an efficient heat transfer device/mechanism and a designer thermo-fluid are necessary. Nanofluids and Phase Change Materials (PCMs) have been developed to increase the thermophys ...

With the recent events of September 11th, there is an urgent need for continuous surveillance of the US border. High altitude airships (HAAs) will have the ability to loiter above stationary targets at altitudes over 70,000 feet, however, they will require power systems capable of sustaining long term flight while requiring no refueling. Lynntech Inc.'s patented unitized regenerative fuel cell ( ...

A SOF Tactical Repeater will be a small, rugged, lightweight, programmable, easily deployed, software radio repeater that can be awakened via RF, by an authorized user, from a passive sleep mode. One or more antennae should be deployed away from RF shadowing, with line of sight to all users. In Phase I, Lambda Science will develop emplacement / antenna deployment methods, standby / wake-up metho ...

Because many chemical and biological toxins selectively target respiratory endothelial cells, a biosensor using these cells in combination with Electric Cell-substrate Impedance Sensing (ECIS) technology has many useful applications for detection and early warning monitoring of a broad range of toxic agents. In the Phase I SBIR program, Agave BioSystems was highly successful in demonstrating that ...

MaxPower's Phase I program will involve development of new cathode materials and new electrolyte solutions to significantly improve gravimetric energy densities and rate capabilities. With these objectives in mind, the following details the approaches MaxPower will take in its Phase I program. To improve gravimetric and volumetric energy densities and rate capabilities, the Phase I program will sy ...

Despite the extensive research expended on developing high Tg resins for composite filament winding applications, these resins require heated processing which limits their general acceptance in current production facilities. New filament winding matrix resins are therefore under development to overcome this limitation. TRI/Austin developed preliminary hybrid resin formulations in Phase I that are ...
