Abstract:TUI proposes to complete the development of two novel technologies that will enable pico-satellites in LEO to efficiently close the link with standard issue handheld radios on the ground. The first technology is a dual-band software-defined radio (SDR) that will provide UHF SATCOM to soldiers on the… more
Abstract:The technological systems on which today's war-fighters depend, reflecting today's society, are vulnerable to the effects of sudden high-energy events from our Sun. Because the propagation speed for sudden increases in X-rays from a solar flare is the speed of light, it is necessary to… more
Abstract:ABSTRACT: Thermospheric densities are critical in determining orbital drag for providing collision avoidance warnings for manned and unmanned spaceflight, accurately cataloging orbiting objects, predicting reentry times, and estimating satellite lifetimes, on-board fuel requirements, and attitude… more
Abstract:ABSTRACT: With the increasing age of current military aircraft fleets and current operational and budget environment, there is a need to increase structure reliability and availability while, at the same time, reducing maintenance costs. This is critical especially when some fleets need to be… more
Abstract:High order mode (HOM) absorbers are very important to stable operation of accelerators. It has
been very difficult, especially for superconductor radio frequency (SRF) accelerators, to find a suitable HOM absorber material that not only can function at cryogenic temperatures and
Abstract:SK realistic estimated timeline of 18 months maximum, hopefully sooner, will allow for design, engineer and testing modifications to be addressed. SK learned from Phase II that even the simple modifications can result in hours of engineering and design work. The successful completion of the DOTWASH… more
Abstract:ABSTRACT: State of the art Orbital Transfer Vehicle systems and GEO transfer missions require the demanding combined requirements of both high Thrust-to-Power (greater than 150 mN/kW) and high specific impulse (greater than 3000 s), all at constant power. The 9 kW PROTEAN system is a two-stage… more
Abstract:ABSTRACT: Orbital transfer missions require a demanding combination of lightweight, flexible operation and high Thrust-to-Power (greater than 120 mN/kW) electric propulsion. Adding Neutral Entrainment (NE) to a pulsed electromagnetic thruster has the potential to dramatically increases the total… 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.
