Abstract:ABSTRACT: Operating in a Service-Oriented Architecture (SOA) environment is risky because there is limited ability to gauge the quality of information, especially information that has been transformed multiple times as it flows within the SOA. To address this problem, CFDRC built METSI (Metadata… more

Abstract:ABSTRACT: Unsteady aerodynamic loading and flow separation on modern high speed aircraft weapons bay doors can excite aircraft structural modes and lead to buffet, flutter, or fatigue-induced failures. Rigorous numerical simulations, wind tunnel and flight tests are typically carried out to… more
Abstract:ABSTRACT: Electromagnetic (EM) devices are used increasingly in society, with applications in communication, medicine, security, and defense, among others. To study safety and potential health hazards of EM devices, high-fidelity voxelized anatomical body models have been used in conjunction with… more
Abstract:ABSTRACT: Establishing adequate access controls that limit access to information without adversely denying access is critically needed by our warfighters in today"s complex battlefield environment. To address this need, CFDRC is proposing an innovative method called CAPSA (Controlling Access… more
Abstract:ABSTRACT: The objective of this program is to tailor and focus the capabilities of an existing software package for prediction of the rapid transient events following ignition of rocket-propelled munitions, as well as the firing of small caliber weapons. These events differ from missile plumes in… more

Abstract:Tungsten and its alloys are candidates for plasma facing component heat sinks and armor due to their low sputtering rate, high melting point, high thermal conductivity, high strength at elevated temperatures and low tritium inventory. However during service, the plasma facing components will be… more
Abstract:Current strategic solid rockets motors, such as the SM-3 third stage rocket motor (TSRM), employ highly aluminized propellants with gas temperatures of approximately 6,500F. Carbon-carbon nozzle throats and carbon cloth phenolic (CCP) exit cones are commonly used to manage the propellant exhaust. … 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.
