Abstract:A critical aspect of operating and maintaining an offshore wind turbine is turbine access. By facilitating crew access to turbine in most any weather, repair and maintenance tasks can be performed in a timely manner. This enhances turbine availability which in turn increases annual energy… more

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:Tethers Unlimited, Inc. (TUI) proposes to develop a system for towing micro Magnetic Anomaly Detection (MAD) sensors from unmanned and manned rotary-wing aerial vehicles such as the Fire Scout MQ-8C VTUAV. In prior efforts, TUI successfully developed a prototype lightweight winch, fiber-optic cable,… more
Abstract:TUI proposes to develop the"Remote Anchoring Module"(RAM), a launch-able anchoring system that can quickly set an anchor and tagline at a remote location without the need for manual emplacement. The RAM device will enable Army Combat Service Support engineers to rapidly, safely, and… 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: Coordinate Registration (CR) of OTHR targets requires accurate real-time ionospheric modeling coupled with HF propagation calculations to convert radar-measured target signal delays and beam steers to geographical position. Our team is the developer of one of the most sophisticated… more
Abstract:ABSTRACT: Chrome plating is used extensively for aerospace and industrial applications because it is wear resistant, corrosion resistant, has a good surface finish and has good adhesion. Aircraft use chrome plating on landing gear components because of these characteristics. However these coatings… 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

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.
