Abstract:Vertical Line Arrays (VLAs) have the potential of significantly improving the performance of underwater acoustic systems in shallow water scenarios. Realizing this improved performance in a low storage volume, cost effective system is dependent on an Integrated Hydrodynamic Deployment System which… more
Abstract:Aircraft which travel at high Mach numbers require a very large internal heat sink to protect the engine and airframe from high heat loads. Endothermic fuels are attractive for hypersonic propulsion systems because they increase the fuel heat sink capacity. We propose to develop a compact and… more
Abstract:We propose development of an innovative system for converting the energy content of refuse to electricity. The key element of the system is a supplementary-fired exhaust-heated gas turbine that has a thermal efficiency of 50%. The engine has two combustors: (1) an exhaust-heating combustor that is… more
Abstract:This project will develop a long duration, open circuit respirator with several key advantages over existing technology: it provides cool, fresh breathing air for long periods (potential up to 2 hours) with an open circuit system, it assures positive faceplate pressure, and it is very lightweight.… more
Abstract:Decompression sickness (DCS) presents a risk of serious injury or death and affects the operational readiness and capabilities of NASA military and civilian astronauts, aviators and divers and other individuals who are exposed to moderate environmental pressure transients. During this project,… more
Abstract:Future spacecraft will require reliable, passive thermal control systems. Capillary pumped loops (CPLs) are currently limited by the performance of conventional capillary evaporators because their heat transport capacity and their heat flux capability are low. We propose to develop a reliable CPL… more
Abstract:This proposal addresses the development of a novel permanent magnet motor for a miniature centrifugal compressor. The compressor is a critical component in a low capacity, vibration free, long life cryocooler. Key features of the development include the incorporation of a permanent magnet in a… more
Abstract:Recent developments in orifice pulse tube refrigerator (OPTR) technology have made these devices competitive with Stirling cycle cryocoolers for long-life spacecraft service, but further improvements in efficiency, capacity, miniaturization, and reliability are required. We propose an innovative and… more
Abstract:Current fabrication techniques for millimeter wave (MMW) waveguide assemblies are inherently costly and poorly suited to realizing economies of scale. Improved processes for manufacturing these components at reasonable costs are required to exploit recent advances in MMW technology. In this project… more
Abstract:The use of robot technology in many military and private sector applications has been limited due to the application-specific nature of available robot hardware and control software. the use of robots with multiple sensors, kinematic redundancy, and mobile bases has been restricted because of the… more
Abstract:Saphikon, Inc. has successfully demonstrated 12 x 24 inch sapphire sheet growth using the Edge Defined Film Fed Growth (EFG) technique. Therefore the focus of this program is to identify and demonstrate solutions to the technical problems imposed by the strict specifications of the "electronic… 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.
