Abstract:Gas Metal Arc Welding (GMAW) is the most widely used welding process. It is also the major process used in shipbuilding. In traditional GMAW and all its modifications, the current which melts the wire is the same as the current which heats the base metal. The base metal heat input is thus… more
Abstract:Orbital pipe welding systems are not true emulation of skilled welders who adjust welding parameters based on observation on the weld pool. This SBIR Phase II project aims at the development of commercial prototype systems which can adaptively adjust welding parameters based on an observation on the… more

Abstract:xxxIn-situ fiber placement is able to offer a wide and robust processing approach that is well suited for many aerospace structures. Flat, single curvature and large radius complex curvature parts can be effectively handled with the current in-situ techniques. However, there are limitations… more
Abstract:Commonly, composite rotor blade spars are fabricated by hand layups or other non-optimized, not fully automated procedures. These methods are labor intensive and require many de-bulking steps, making them expensive. The results are often inconsistent due to the nature of work done by hand. In our… more
Abstract:Increased performance and reduced cost structures, is the direction many aerospace companies work toward. Our objective in Phase I is to demonstrate our automated in-situ fiber placement processing technology can provide low cost manufacturing methods with thermoplastic composites while maintaining… more
Abstract:Optimize process to meet the specifications and challenges associated with the UH-1 tail boom. This will entail performing testing and evaluation of the factors deemed most relevant. This could include, but is not limited to material property testing, tooling design, tooling trials, in-situ… more
Abstract:A short-pulsed neutron generator is proposed for the detection of concealed high explosives. A recently developed RF-excited plasma neutron generator will be pulsed to produce the activating neutrons whose pulse length is 5-10 ns with a repetition rate of 100 kHz. Using the D-T nuclear reaction, we… more
Abstract:Refractive lenses can dramatically improve neutron instrumentation in DOE facilities. In previous experiments, compound refractive lenses (CRLs) were shown to be capable of imaging using thermal neutrons. However, a number of problems exist that prevent the full implementation of these lenses: the… more
Abstract:A pulsed neutron generator is proposed for the detection of special nuclear material. A recently developed microwave-excited plasma neutron generator will be pulsed to produce the activating neutrons whose pulse lengths vary from 100 microseconds to 2 ms with a fall time of less than 1 microseconds.… more
Abstract:The accurate detection of neutrons can make invaluable contributions to the physical, chemical, and biological sciences, and the DoE operates neutron user facilities to support these endeavors. The utility of prisms for neutron detection has long been established, but a single neutron prism has… more
Abstract:Aging and durability of aircraft in both the military and civilian sectors are becoming major issues as the existing fleet continues to age. Additionally, the increased use of composite structures in the civilian fleet, such as in the Boeing 787 Dreamliner and the Airbus A380, make the… more
Abstract:Establishing human presence outside the protective cover of earth's atmosphere is a challenge. On earth, the atmosphere does not only present breathing gas, it also acts as a thermal buffer and protects the biosphere from harmful radiation. Shielding of humans from harmful radiation during… more
Abstract:Any manned missions to extraterrestrial locations will require shelter structures for a variety of purposes ranging from habitat usage to biomass production. Such shelters need to be constructed in such a way to minimize stowed volume and payload weight. The structures must also be very durable… more
Abstract:The proposed Phase I program will demonstrate the feasibility of the in-space production of large aperture antenna structures. The use of a novel open cell foam, previously developed for NASA space antennas, will allow the deployment of reflectors at low cost and very low transport volume compared… more
Abstract:The threat of explosive-laden vehicles driving in close proximity to military installations has been a major concern since the attacks on the USMC headquarters in Beirut in 1983. The large quantity of explosive a single truck can carry combined with the sheer power of a heavy vehicle driven at high… more
Abstract:The Missile Defense Agency (MDA) is soliciting proposals for new missile materials to expand the capability of current air-to-ground missile systems. This expansion of capability dictates the development of lighter weight materials that are capable of short duration exposures to temperatures as… 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.
