Shipboard structures employing composites typically use glass/vinyl ester (VE) manufactured with vacuum assisted RTM. This composite system offers reduced weight, no corrosion and improved signature performance but lacks the fire performance characteristics required for shipboard use. Phenolic resins (PH) provide outstanding fire performance but are difficult to process and offer lower structur ...

Nanophase metal particles are becoming increasingly important in areas such as powder metallurgy, catalysis and energetic materials. One of the more important nanophase metals is aluminum . Although several promising routes for the production of this material exist, not one of these synthesis techniques have successfully addressed the issue of the oxidation of these same nanoparticles, which lea ...

Ultrafiltration membranes offer great potential for compact, low cost clean-up of Navy surface ship graywater and blackwater. A major limitation of these ultrafiltration membranes is significant loss in flux with time associated with membrane fouling from proteins, polysaccharides, and other waste products. Backflushing can only be used to a limited extent. Chemical treatments are undesirous si ...

Elsicon Incorporated proposes to develop an optical demultiplexer appropriate for use in high bandwidth fiber-optic communication systems. The demultiplexer will be capable of reducing an optical input bit stream with an aggregate bit rate of greater than 100 Gbits/sec down to a 1 Gbit/sec baseband rate. Therefore, by distributing the full serial data stream among an array of these devices, ultrah ...

The US Air Force plans to develop and demonstrate an aero-propulsion engine for hypersonic flight to Mach 8. This program focuses on use of hydrocarbon fuels and expendable engine designs for long-range cruise missile applications. A critical element for realization to the Air Force's hypersonic vehile mission is advancement in supersonic combustion ramjet engine technology. Development of conc ...

Substantial operational savings and cost reduction can be met for gun barrels and liners with development of materials, processes and/or components/equipment that exhibit wear and erosion protection characteristics greatly improved over current materials and methods. Utilizing self-propagating, high-temperature synthesis (SHS) techniques, functionally-graded property, gun barrel/liner production m ...

As pulsed power devices mature a requirement emerges for the efficient coupling of the power source of remote locations. For certain applications this coupling can take the form of existing high power switch/conditioning technology coupled with a suitable transmission line. For mobile, remote or harsh environments standard connection techniques are too bulky and require too much set-up time to b ...

This project enables and incentivizes adaptation of IEEE Draft Standard 1076.1 (VHDL AMS) by mixed signal (analog/digital) engineers by providing a feasible, low risk migration path for existing SPICE like models (equivalence), then adds capability beyond that of SPICE (incentive). Specific work items include "black box" VHDL AMS source code generator technology, SPICEcompatible analog solver tech ...
