Traditional weapon systems often fail to meet the requirements of close combat typical of the previously discussed engagement, where insurgents often blend in or store weapon amongst friendly or non-combatant forces, to shield them from precision strike munitions of a technologically superior force. This type of warfare has led to an increased focus on the use of less-lethal weapons, to reduce let ...

In an effort to development more robust optical system coatings DTRA, in collaboration with Sandia National Labs, is working to characterize the degradation of optical materials for space systems when exposed to high intensely EUV/ cold x-rays. The experiments utilizes the Double Eagle z-pinch facility which generates high current, high voltage arc pinch plasma to produce an intense EUV and cold x ...

Space platforms are complex dynamical systems and there are many reasons to model them from ground telescope imagery as well as from space-based sensor platforms. One key motivation is to determine the operational state and configuration of the vehicle. Key questions such as did the solar panels fail to deploy, did the object begin to tumble unexpectedly may be addressed by a sufficiently detaile ...

Production of hydroxylamine nitrate (HAN) and hydroxyethyl hydrazine nitrate (HEHN) is of great concern for the manufacture of AF-315E. Current stockpiles of heritage ingredients held by AFRL are being depleted and those manufacturers are no longer in exi

Current and future explosive munition weapon systems development relies heavily on explosives detonation performance characterization and computational hydro-code simulation research conducted by DoD and DoE research communities. This work in turn relies

This Phase II STTR effort is focused on generating the data necessary to identify the phenomenology that produces carbon deposition within kerosene film cooled rocket engines.This data is essential to guide the model development and validation process.Program outputs will be both data and a physics-based model for carbon deposition.

ABSTRACT: While the state of the art in both single-image reconstruction algorithms and multi-view structure from motion algorithms have advanced considerably in recent years, little work has been performed which leverages the constraints relied upon by both approaches. When an area of interest is imaged from a long distance with little angular diversity in viewpoint, multi-view constraints alon ...

ABSTRACT: Flow Modeling and Simulation, LLC (FMS), proposes to develop a computational software tool, herein designated AUG3D, that is intended to provide physics-based, multi-level, validated computational simulations of turbine engine component flow fields, particularly those associated with thrust augmentors, i.e., afterburners. This tool will be ideally suited for closely integrating physica ...

ABSTRACT: VSI proposes a flexible sensor estimation framework for airborne calibration processing of image streams over long time periods. The components of the framework will consist of existing software and libraries. The plugin-based framework provides flexibility to switch the components easily. The core of the framework is a belief propagation engine to globally optimize the sensor parameter ...

ABSTRACT: The SCRAMSIM computer code will be able to perform analysis for engineering design, stemming from a low order Reynolds Average Navier-Stokes (RANS) to high order (4th or higher) LES using accurate subgrid scale models (SGS). It will also solve thermal non-equilibrium mechanisms, conjugated heat transfer, general finite-rate chemistry using several databases for hydrocarbon/hydrogen-air ...
