Abstract:Not Available Directed Energy Weapons (DEW) are rapidly becoming attractive due to their reusability and the fact that unlike mechanical weapons which rely on magazines of explosive shells, these weapons rely on power supplies. The most attractive aspect of DEW weapons lies in the fact that an… more
Abstract:Not Available To prevent high cycle fatigue (HCF) failure in turbine engines requires verification of analytical assumptions and substantiation of design adequacy as a key aspect of the engine design process, and realistic modeling of vibration in turbine engine requires extensive experimental data… more
Abstract:Not Available The Department of Defense has expressed a need for an inexpensive inertial navigation system (INS), based on small-size, low-cost inertial sensors. Earlier designs could not be employed in many practical applications due to their restrictive specifications (high cost and low accuracy)… more
Abstract:Not Available This Small Business Innovative Research Phase I project will develop a system that provides a positive indication to the catapult officer when an aircraft launch bar is properly seated in the catapult shuttle of an aircraft carrier. Improper launch bar seating has resulted in the loss… more
Abstract:Not Available The IR Devices, Modules, and Materials Group at Structured Materials Industries (SMI) proposes the development of high efficiency tandem cells based on antimonide materials for thermophotovoltaic (TPV) applications. The structure of this device will be a dual-junction monolithic… more
Abstract:Not Available In Phase I of the program, we will demonstrate fabrication of IR-transparent, dense, nanocrystalline (< 100 nm) aluminum oxide (Al2O3) discs by microwave sintering of nanopowder compacts. Such a material is a potential replacement for the more expensive sapphire (single crystal Al2O3)… 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.
