The proposed project will rectify the current bottleneck in the simulation of 3D magnetic fields around high-current pulsed power devices. In the existing software, fields in the air are approximated by an artificial magnetic diffusion equation, which is both computationally expensive and nonphysical. The proposed solution avoids any nonphysical quantities and relies on exact conditions for the qu ...

Understanding the response of solid rocket motors under cookoff and projectile impact scenarios is important to the safety of the military’s weapon arsenal. In this SBIR, CFDRC, teamed with Merrill Beckstead of Brigham Young University (BYU), propose to develop an improved modeling tool for simulating the response of solid rocket motors containing AP/HTPB/AL propellant to external heat and impa ...

Understanding the response of solid rocket motors under cook-off conditions is important to the safety of the military’s weapon arsenal. In this SBIR, CFDRC, teamed with Merrill Beckstead of Brigham Young University (BYU) and ATK Launch Systems, proposes to develop a software toolkit for simulating the response of solid rocket motors (SRM) to fast cook-off events. The complete software package w ...

CFDRC proposes to develop a comprehensive, high fidelity commercial quality simulation tool for modeling the Cold Hearth Melting (CHM) processing of Titanium alloys. The code will accurately predict the transient temperature distribution, flow patterns, skull shape, species evaporation, and particle fates in the hearth region for a given set of dynamic operating conditions. The foundation for this ...

The goal of the proposed research is to develop a unified computational framework integrating adequate physical models for simulating complex non-equilibrium plasmas. Plasma dynamics is characterized by disparate spatial and temporal scales each described by appropriate physical models. The project aims to classify possible scenarios and develop general recipes for clustering phase space to dynami ...

A coupled transport, fate and human effects model is proposed that may be used to better understand and minimize the occupational exposure encountered during the maintenance of aircraft and other associated weapons systems while improving their operational efficiency. In Phase I a Computational Fluid Dynamics-based, micro-scale transport and dispersion model will be integrated with lung deposition ...

Space-based systems have become indispensable elements of global communication, scientific research and military reconnaissance. The expenses associated with launching spacecraft are enormous and, once in orbit, any component failure may have catastrophic consequences. Extensive earth-based testing is essential to ensure a high success rate. To approximate the demanding conditions of space depl ...

The Active Resource Manager (ARM) will perform dynamic decision-making for self-managing networks. To accomplish this, ARM will access information from a wide range of network resources and cyber-defense sensors, and it will use this information to generate and maintain a situation awareness model. The situation model will consist of a structured, dynamic representation of significant situation p ...

Active Response is the capability for a computer network system to respond to cyber-attack defensively. When an attack is detected, the system takes appropriate steps to mitigate its effects. The proposed Active Response Console (ARC) will provide such a capability. The ARC will enhance Sentar's current computer network defense (CND) capability by integrating active response into its Work-Cent ...

This proposal will demonstrate the feasibility of producing diffraction-limited anamorphic microlens arrays for Shack-Hartmann wavefront sensors used on very large aperture astronomical telescopes with multiple off-axis laser guide stars. A high-quality lenslet arrays will be fabricated with gray scale mask lithography and reactive chemical etching. Four advanced gray scale photolithographic mask ...
