The Defense Modeling and Simulation Office (DMSO) has developed the High Level Architecture (HLA) as one of the principle components of a DoD-wide Common Technical Framework for modeling and simulation (M&S). Unlike previous distributed simulation technologies such as DIS and SIMNET, HLA provides federation developers, via the Object Model Template (OMT), the means to define the structure and for ...

AeroSoft, Inc. proposes to develop, incorporate and validate transition and anisotropic turbulence models for improving the low-Reynolds number predictions for high-lift airfoil configurations. The turbulence-modeling package will use Menter's two equati

The proposed prototype Operational Trainer for the FFG-7 AAW Combat System will provide the US Navy with a means for training the FFG-7 AAW combat team to operate their equipment in condition 1 watch stations. Each watch station will be provided with the ability to train as they fight by allowing continuous on-board AAW training that includes all elements of the combat system with interactions as ...

Attachment areas in the regions of rotating components of gas turbine engines degrade due to fretting wear and fatigue. Plasma sprayed coatings are often used to protect these regions. A thin, dense, Ti(C, N) composite coating based on sol-gel process is proposed. The simple, cost-effective sol-gel process will coat complex shapes and will provide superior performance against fretting wear. Di ...

Measuring the inherent optical properties of the ocean has historically been a very difficult problem. The most widely used in-situ sensor has been the transmissometer, which measures the transmission of a light beam over a short pathlength in the water. More recently, sensors have become available that measure light absorption and optical backscattering. Absorption and beam attenuation are non ...

The objective of the proposed Phase I work is to demonstrate the feasibility of using the Choi-Williams distribution to estimate the time ¿ frequency distribution of transients of interest to the IUSS. The specific objectives are to develop a metric for IUSS images and to show that the Choi-Williams distribution of these images may be used for classification. The Choi-Williams distribution is ...

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 ...

The process of electro-explosion of metal wires, first practiced by Faraday was first developed by G. Ivanov of Russia in 1975 for the production of nanometer metal powder. Extensive R, D and E plus production was done on aluminum(Alex) and copper. Kg. quantities have been made of Sn, Zn, Fe, Ni, Ta, Mo, W, Ti, Zr, and Fe. The process can use any metal so long as it is available in wire of ...
