Abstract:DESCRIPTION (provided by applicant): Melanoma is the most common form of cancer in young adults1, and its incidence is rising at a rate higher than any of the seven most common cancers2, increasing 45% between 1992 and 20043. Plexxikon and Roche are codeveloping a BrafV600E inhibitor (i.e.… more
Abstract:To address the issue of heat transfer from the rocket motor nozzle exit cone into the metal support housing MSI proposes to apply a well-developed, highly insulating interlayer material, quartz polysiloxane Qz/Ps, between the exit cone surface and the metal substructure surface to maintain that… more
Abstract:This Statement of Work (SOW) defines the support required for a multi-task effort related to the design and fabrication of a ceramic resin matrix composite nosecone to fulfill Block IIB mission requirements. MSI will develop composite material component designs that fulfill the aerothermal and… more
Abstract:Diode-Pumped Alkali Laser Systems (DPALS) have great potential for missile defense and other applications. These systems require a uniform, steady, flowing mixture of helium and rubidium vapor at elevated pressure and temperature. Significant challenges exist because rubidium is a very reactive… more
Abstract:Next generation aircraft systems will include weapons, sensors and actuators requiring large amplitude pulse power capability which will exceed the continuous power delivery capacity of most aircraft. Compact, lightweight and efficient power conversion and thermal management systems are required to… more
Abstract:To accelerate advances in cognitive science, and to facilitate the invention of novel brain-centered technologies, tremendous benefit would be gained by expanding the accessibility of Electroencephalography (EEG) to non-traditional users. A key driver for expanding accessibility is lowering cost… more
Abstract:Despite over 100 years of research, decompression illness (DCI) remains the mission-limiting factor in the design and execution of combat dives. Divers may spend over an hour decompressing after spending as little as ten minutes at the target depth. While decompressing, the diver is limited in… more
Abstract:Chemical, biological, or toxin attacks in military and civilian settings are a serious and growing concern. Standard first aid for exposure to many chemical warfare agents and toxins includes the immediate administration of relevant antidotes using an autoinjector. When an attack occurs, prefilled… more
Abstract:Soldiers recovering from mild traumatic brain injury (mTBI) or relearning how to walk on a prosthetic lower limb often struggle with their balance. Of patients recovering from acute blast-induced mTBI, almost all (90%) report unsteadiness. These balance deficits affect ability to return to duty… more
Abstract:Effective Army-scale mobility predictions in austere environments require knowledge of soil strength conditions at high spatial resolution (100 m or less). The Army"s knowledge of the battlespace is greatly hindered because available weather-scale near-surface soil moisture data, a primary… more
Abstract:Small unmanned aerial systems (UAS) are a critical element in current military operations, and their use will increase substantially in the future. The propulsion system is a key design constraint in any UAS, and current small gas turbines for these vehicles are limited by the conventional… more
Abstract:Power system upgrades for next-generation ground combat vehicles require technology advances such as higher operating temperature, greater power density, and increased functionality. Silicon Carbide (SiC) based power electronic devices offer advantages over silicon devices, especially for high… more
Abstract:ABSTRACT: Current separable thermal mechanical interfaces (STMIs) found in advanced digital processing electronics are unable to efficiently remove dissipated heat from the active electronics, limiting electrical performance far below their capability. The standard approach produces high thermal… more
Abstract:ABSTRACT: The Air Force uses specially designed facilities to perform ground testing of infrared detector focal plane arrays at Arnold Engineering Development Center (AEDC). The current approach for cooling the detectors down to 8 K utilizes liquid helium. The systems to transport and store the… more
Abstract:Diode-Pumped Alkali Laser Systems (DPALS) have great potential for missile defense and other applications. Proper design of these systems is challenging because many interrelated processes impact their performance and critical kinetic rate coefficients are not well known. In response, our team… more
Abstract:ABSTRACT: The efficient, effective balancing of jet engine rotors and subassemblies continues to be a challenge for key aerospace applications. While manufacturing methods for balancing have improved significantly over the last ten years, measurement methods and procedures and fixturing have not… more
Abstract:ABSTRACT: Accurate determination of the distance between fastener holes and part edges is critical to ensure structural integrity in military aircraft. These measurements are particularly important as part flanges are reduced and tolerances are tightened to save weight and increase performance. … more
Abstract:Hybrid turboelectric aircraft with gas turbines driving electric generators connected to electric propulsion motors have the potential to transform the aircraft design space by decoupling power generation from propulsion.

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.
