Abstract:US Navy efforts to develop effective torpedo countermeasures have yielded mixed results, but improvements are on the horizon. However, the relatively small number of sensors on each ship limits the military utility of the torpedo defense picture currently available to ship commanders. For effective… more

Abstract:Industrial hydrogen production relies primarily on natural gas and hydrocarbon feedstocks to drive the various reaction chemistries that lead to hydrogen generation. Carbon dioxide, the ultimate co- product when such feedstocks and processes are employed, necessarily becomes a major contaminant of… more
Abstract:The U.S. DOE is very interested in promoting on-board vehicular hydrogen storage systems that will enable a driving range of greater than 300 miles while meeting packaging, cost, safety, and performance requirements. State-of-the-art hydrogen storage vessels that meet these requirements are… more
Abstract:ABSTRACT: Cavitation which leads to head falloff and feed system instabilities are a constant source of problems for the low net positive suction head (NPSH) pumps that are needed for advanced liquid rocket engines. Head falloff limits the pumps capability to deliver propellant at the required… more
Abstract:On today"s battlefields, vehicles are at risk of encountering improvised explosive devices (IEDs). Fortunately, not all of these result in complete vehicle loss. Following events at both ends of the severity spectrum, Battle Damage Assessment and Repair (BDAR) and event reconstruction efforts… more
Abstract:The work to be conducted under this proposed effort will include design, analysis, and manufacture of composite sabot/pusher assemblies for US Navy specified sub-caliber gun launched HVP flight configurations. The overall scope of work will be divided into a Base, Option 1, and Option 2 efforts… more
Abstract:Creating information products to answer"Tell Me About"questions requires the ability to identify key pieces of information relevant to a complex set of information requirements. Complicating matters, these key pieces of information exist in multiple modalities scattered across data stores,… more
Abstract:Modern military and commercial aircraft include numerous RF systems and associated antennas serving a multitude of functions. The designed free-space performance of these antennas can be degraded by their installation on the airframe due to interactions with the platform, and the co-siting of so… more
Abstract:Modern military systems contain numerous avionics and electronic systems that must perform to very high standards in hostile environments in the presence of numerous potential sources of electromagnetic interference (EMI). On airborne platforms for example, there could be dozens of RF systems… more
Abstract:ABSTRACT: A key problem in the rapid and lower cost development of spacecraft is that the various devices that comprise the spacecraft bus do not typically provide a single standard interface and/or communications protocols. This forces a design-to-order paradigm in which a spacecraft bus is… more
Abstract:In Phase 2, Diffraction LTD, in collaboration with Optics 1, proposes to develop a variable magnification clip-on thermal imager (VM-COTI) that will be compatible with a variety of weapon and head mounted optical systems ranging from 1X night vision goggles (NVGs) to 5X ACOG scopes. The VM-COTI… more
Abstract:ABSTRACT: Environmental protection coatings are required to provide oxidation and hot corrosion protection to hot section turbine components. Unfortunately, the current generation of such coatings can degrade the fatigue resistance of the coated alloy. It is increasingly recognized that, due to… more
Abstract:ABSTRACT: Thermal barrier coatings (TBC) are currently employed to protect gas turbine engine components. Thermally exposed TBC systems have been observed to be affected by moisture. This spallation mechanism, Moisture Induced Delayed Spallation (MIDS), occurs at room temperature while the coatings… more
Abstract:The goal is to develop external mechanical filters to eliminate signals above 2 kHz from accelerometers. Dominca"s patented layered-media approach will be used to develop filters for high-shock accelerometers used in explosive and impact events. Layered-media theory has been applied… more
Abstract:Inductive pickup loops are one of the primary magnetic diagnostics in modern fusion concepts. To convert the voltage measurement from the inductive pickup loop to a measurement of magnetic field, the loop voltage must be integrated. While simple in principle, in practice several factors make the… 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.
