The proposed research combines an innovative eigenvector method with other electromagnetic techniques to produce a hybrid approach towards solving the EM coupling to satellite cavity problem. The physical structure is divided into an exterior region and one or more interior regions. The exterior region is modeled with method of moments (MOM) and or hybrids of MOM with the uniform theory of diffr ...

The nuclear weapons community has traditionally focused on the next generation or level of weapon capability complimented by gathering and analysis of actual test data. Now, with the cessation of actual weapons testing, there is an increased need to use the actual test data in modeling techniques to better understand the phenomenology and potential effects of nuclear weapons. The first phase of ...

Under the proposed research an Interface-Driven Design Manager (IDM) for CAD packages will be developed to greatly reduce the design cycle time for aircraft structures. The IDM represents a first attempt to fully integrate powerful new interface element and design management technologies into the CAD environment. These emerging technologiies have the potential for making multidisciplinary design ...

Recent efforts in the target vulnerability community (fixed ground targets, mobile ground targets, and aircraft) have focused on enhancing the blast and fragmentation modeling from weapon detonations. This includes modeling propagation of the detonation effects from the weapon through their interaction with the target geometry, to the development of loads on and response of the target structure. ...

Warhead design calculations and weapons effectiveness estimates require a methodology to predict structural response and the associated damage to air targets from reactive munitions. The objectives for the proposed Phase I study effort are to develop candidate launch conditioning, reaction initiation and reaction rate methodology, to incorporate existing ballistic, blast and quasi-static pres ...

Turbulence of gas flows by its very nature is one of the most difficult things to model and measure. We propose to develop a new way of measuring the turbulence and to compare these measurements to predictions using the k-epsilon model. Typical measurements, in the past, use smoke, Schlierin or shadow graph techniques to visually infer turbulence characteristics. These features are either motio ...

The objective of this work is to develop analytical techniques to characterize wear and gouging phenomena of slippers at speeds up to hypersonic and demonstrate means to evaluate or reduce slipper wear/gouging. Specifically, we will develop analytical techniques that can be used to predict slipper wear patterns and gouging phenomena throughout the sled velocity regime to Mach 10. This will inclu ...

The use of advanced composite materials in all applications has increased dramatically, but the methods for managing and processing have remained unchanged for thirty years. Advanced, mulitple sensor technology has been demonstrated to reduce process time and costs. AvPro proposes to develop a single sensor system to provide multiple data inputs. It would be a means to validate models for proce ...

The process described in this proposal has the potential to dramatically reduce the costs of removing nitric oxide (NOx), carbon monoxide (CO), dry particulate matter (DPM,soot), Volatile Organic Compounds (VOCs), unburned products of combustion, and other hazardous air pollutants (HAPs) that may be effluents from AF maintenance or training operations, and stationary diesel powered ele ...

A need to control the fugitive emissions of hazardous vapors, volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) has been identified in operations at Army plants and depots. The High Mesa Technologies (HMT)/Coyote Aerospace team proposes to meet this need using proven silent discharge plasma (SDP) techniques, developed by the Electric Power Research Institute and Los Alamos Nat ...
