Abstract:We propose to develop sensor technology capable of high resolution imaging of electromagnetic radiation in the energy spectrum spanning the ultraviolet to x-rays. Phase I calls for the fabrication of small scale image sensors. These sensors are fabricated from CMOS arrays, coated with selenium and… more
Abstract:An effective process for recycling plastics and composites used in aircraft does not currently exist. As a result, scrap and used materials are disposed of in landfills. A chemical recycling process is proposed that will allow the components of these waste materials to be converted to valuable… more
Abstract:A novel tertiary recycling process is proposed for investigation as an economical means for reclaiming scrap aircraft transparency materials. Early development work has shown that this process can convert a wide variety of polymers and composites into low molecular weight hydrocarbons at… more
Abstract:A modified engine cycle based on the early intake valve closing of the Miller or the Adkinson cycle is proposed to meet the needs of the future Military Advanced Diesel Engine. The concpet involves the principle of short, effective compression with long expansion ratio to provide high brake thermal… more
Abstract:Current designs for rural safety mailboxes combined with a lack of safety design regulations, produce a hazardous situation for errant rural motorists. When impacted, rural mailboxes have been shown to dislodge from their posts and penetrate automobile windshields. In addition, rural residents are… more
Abstract:Adroit Systems, Inc. (ASI) is proposing to develop the concept of a geometric vector that is updated by deeply integrated avionics sensor data. Deep integration is a technique of sensor fusion that promises greater performance and robustness than possible with cascaded frameworks. Many of today's… more
Abstract:An important aspect in the design of aircraft structure and aeropropulsion components made of high temperature composite materials is damage tolerance and life prediction. Many components contain joints between composites and metals. There is a need to develop methods for predicting life of such… more
Abstract:A novel coating technology is proposed for the protection of naval weapon components. Diamondlike nanocomposites constitute a new class of materials that exhibit unique combinations of technologically interesting properties including high adhesion to vertually any substrate (including metals,… more
Abstract:A new class of thin film materials, diamond-like nanocomposites (DLN), have been developed that represent a significant advance over "conventional" diamond-like carbon coatings. The co-efficient of friction of DLN is a fraction of that for DLC and diamond, and the temperature stability much higher… more
Abstract:Pulse power batteries based on the high-temperature Lithium-Metal Sulphide (LiMS) system are of interest for miliary applications. However, improvements in minimized size, maximized power density, maximized life, and reduced cost are needed to meet all Army requirements. Many of the battery… more
Abstract:OHMIC CONTACTS ARE KEY TO THE IMPLEMENTATION OF SILICON CARBIDE (SIC) HIGH POWER, HIGH TEMPERATURE DEVICES. TO DATE, CONTACTS TO SiC MADE USING CONVENTIONAL TECHNIQUES HAVE DEMONSTRATED NEITHER LOW CONTACT RESISTANCES NOR LONG TERM STABILITY. IN PHASE I WE WILL DEVELOP LOW RESISTANCE SILICIDE BASED… more
Abstract:Infrared sensors and sensor arrays are widely used in military and commercial applications such as night vision, medical diagnosis and weather mapping. Expensive quantum effect sensors, such as HgCdTe systems, must be cooled to liquid nitrogen temperatures and are difficult to produce with uniform… more
Abstract:Structural composites have many applications to 2500 Degrees F and beyond, in oxidizing environments. Oxide fibers within intermetallic or oxide matrices are the top candidate systems for satisfying these conditions. Suitable fiber/matrix interface coatings are critical, but their development has… more
Abstract:The ability to control large amounts of power (1-150kW) is necessary in applications ranging from aerospace to consumer electronics to industrial power systems and transportation. In order for silicon and gallium arsenide devices to meet such high power densities, tens of devices must be combined to… 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.
