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 ...

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 ...

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 ...

An Adaptive Multiwaveform (AWF) LADAR design will be developed; the critical technological components tested; characterized and laboratory experiments conducted and modeled to clearly establish feasibility. In Phase I, using high-speed InGaAs and electron-initiated avalanche photodiodes (eAPDs) and high performance amplifiers, the combined effects of varying the waveform’s temporal amplitude, ph ...

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 ...

To better quantify the benefits from the advanced microlens technology developed in the Phase I we plan to have microlenses installed in three astronomical telescopes. In Phase II we are planning to complete the fabrication of the remaining 4 microlenses needed for Gemini telescope and ,also fabricate microlenses for SOR telescopes in New Mexico (NGAS)and Hawaii. This will provide a direct evalua ...

This proposal is for the development of an architecture for asymmetric and anti-terrorist simulations and the application of that architecture in the design and development of multiple user-friendly, PC-based, artificially intelligent asymmetric combat simulation systems. This effort will utilize a number of existing, mature computer wargames and will focus on enhancements to those game systems u ...

During Phase I CFDRC defined the performance and a roadmap for reduced operational costs of existing and new launch platforms using a Bi-propellant Air-Turbo-Rocket (BATR) as first stage propulsion. Specific applications include the Orbital Sciences Pegasus launch vehicle and an innovative Nano Satellite Launch Platform (NSLP). Phase I concluded that the BATR’s specific thrust (200 lbf-s/lbm) ...

Akita is a software-based situational awareness system that aids in the protection of sensitive applications by using inherent system characteristics to generate unique encryption/decryption keys. Similar to biometrics taken from humans, digital metrics can be used to create a unique fingerprint of a compute system, or network. The fingerprint generated can be used to unlock protected data or app ...

We propose to develop an advanced modeling tool to predict and to alleviate cavitation related turbopump instabilities. An existing “full cavitation model” developed by the proposing team and used in commercial CFD codes will be used as the starting point. The model will be improved by: a) introducing Eulerian-Lagrangian coupling for bubble dynamics; b) introducing a multi-scale model to st ...
