Abstract:Not Available This SBIR project proposes to develop a fuel pulsing Lean Direct Injection (LDI) nozzle that reduces nozzle blowout equivalence ratio (phi) and reduces NOx emissions by 90% compared to ICAO 1996 standards. In contrast to high frequency (> 10,000 Hz), low
Abstract:Not Available The Navy has made applying Commercial-Off-The-Shelf (COTS) technologies to the development of naval combat systems a critical priority. Under this new development paradigm, as combat system data processing components become obsolete or requirements grow, faster and less expensive COTS… more
Abstract:Not Available Ultra-Wideband (UWB) antennas for Unmanned Aerial Vehicles (UAVs) have been a challenge for some time, due to size and weight requirements. Such antennas can aid a number of missions in a cost-effective manner, including Synthetic Aperture Radar (SAR), Foliage Penetration (FOPEN),… more
Abstract:Not Available Conducting Materials Corp. Proposes to support the antimalarial structure-based discovery efforts at Walter Reed Army Institure of Research, Division of Experimental Therapeutics. Specifically, serine hydroxymethyltransferase, an enzyme intimately linked to the metabolic functions… more
Abstract:Not Available Essential elements of today's highly mobile military services are effective mobile and temporary shelters. Increasingly, there is a demand for large, easily deployed, temporary shelters for many aspects of military activities. Current shelters are generally not well insulated… more
Abstract:Not Available Portable shelters and tents used by the U.S. Army in field operations for maintenance of vehicles and aircraft, as hospitals, and as billeting for personnel have no built-in insulation capability and rely on huge environmental control units (ECU) to establish a reasonable working… more
Abstract:Not Available Composite tubes for cryogenic cold-to-warm support structures with an isogrid structure will be developed that have lighter weight, lower thermal conductance, and equivalent compressive strength to those currently in use. Previous attempts to produce composite isogrid tubes, using the… more
Abstract:Not Available DSR proposes development of new innovative display formats that will facilitate multi-disciplinary and multi-sensor presentation of data in surface combatant combat systems. The results of this Phase I effort will provide prototype displays that efficiently present, manage, and… more
Abstract:Not Available Innovative device designs and novel growth and fabrication techniques will be investigated to provide a significant improvement in the operational characteristics of A1GaN/GaN high electron mobility transistors (HEMTS). Three novel GaN-based HEMT structures based on the strain… more
Abstract:Not Available There is a need for a fundamentally sound and experimentally validated methodology and software for life prediction for ceramic matrix composite (CMC) propulsion system components and attachments with environmental barrier coatings (EBCs). The present proposal is for a reserach and… more
Abstract: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… more
Abstract:Lean burn spark engines are a promising technique to further reduce both NOx and hydrocarbon/carbon monoxide (HC/CO) engine emissions. Higher lean burn levels improve HC/CO oxidation while simultaneously reducing NOx formation. The NOx reduction is due to cooler flame temperatures. While the lean… more
There are several categories such as “By Agency”, “By Year”, “By State” etc.
Select a checkbox within a category to refine your search results.
Each of your selections is listed in the “Narrow Search Filters” bar. You can uncheck these selections to remove them.
Search for Either Criteria
When you select multiple values within a category, the results will include values that match either of the selections.
For example, selecting “2005” and “2007” in the “By Year” category will display results that include either 2005 OR 2007 in the results.
Narrowing the Search Results
You can refine your search results across categories. To narrow down your results, select multiple values across different categories. The results will only include values that match the selections across the categories.
For example, selecting “2005” in the “By Year” category and “NASA” in the “By Agency” category will only display the results that contain both “2005” AND “NASA” in the results.
