Streamline Automation, LLC, with the support of United Defense, L.P. will develop tools for protecting software executables, and secure inter-unit networking. Modern weapon systems, such as Future Combat System (FCS) rely on a distributed network ofsensors, command elements and weapon platforms. Successful operation will require secure networking between them. In addition, the trend toward the ...

The development of new military gas turbine combustors that produce low emissions of CO, NOx, and unburned hydrocarbons (UHC) is a difficult challenge for designers. Simulation tools that predict emissions are needed to reduce the cost of producingimproved, low emissions combustor designs. In this SBIR, we propose to continue the development of combustion Large Eddy Simulation (LES) methods that ...

High resolution modeling of the aerosolization process for relatively large liquid jets is needed to quantify the dispersion of hazardous chemical or biological agents from damaged/punctured containers. A second application is the prediction of thedistribution of neutralization agents injected into clouds of hazardous chemical or biological agents. A high fidelity model is needed to provide accura ...

Three-dimensional (3-D) integrated circuits (ICs) can significantly improve circuit performance and offer the promise of integrating various technologies (memory, logic, RF, mixed-signal, optoelectronics)within a single block. Lack of 3-D design tools andheat dissipation froThree-dimensional (3-D) integrated circuits (ICs) can significantly improve circuit performance and offer the promise of int ...

Atmospheric pressure non-equilibrium plasma sources are being actively developed for a variety of industrial and military applications. Many of these applications employ ultraviolet (UV) radiation or active species (radicals) generated by the plasma. Theefficiency of plasma sources depends on the energy distribution of electrons which are mainly responsible for the production of radicals and excit ...

During trans-atmospheric flight, a spacecraft passes through both rarefied and continuum flow regimes, which are often described by different physical models. This project aims to develop a unified computer code that can automatically switch betweenkinetic and continuum models while maximizing computational efficiency and ensuring numerical stability. The efficiency of the method will be attained ...

CFDRC proposes to develop a numerical simulation tool uniquely capable of modeling spray cooling concepts for micro-gravity applications. The tool will include effects that are critical in microgravity and cannot be thoroughly investigated using gravitydominated ground-based experiments. The research will rely heavily on the tool to better understand the physics of spray cooling under micro-gravi ...

The project objective is to develop an integrated, hierarchical design tool for simulation of unsteady flows and prototyping of flow control strategies in high-speed combustors. The project directly addresses a need for mixed-dimensionality rapidprototyping software allowing system-level analysis that is not feasible using conventional full-scale CFD modeling. An advanced simulation environment wi ...

In this Phase II SBIR effort, CFD Research Corporation (CFDRC) will continue development of an advanced low emissions fuel injector for military engines that is based on CFDRC's lean direct fuel injector technology. The design produces a unique flamepattern caused by a bifurcated flow pattern, in which the pilot airflow separates from the main airflow and a recirculation zone is created between t ...

Current steady-state CFD combustion codes cannot predict transient combustion phenomena such as lean blowout (LBO) and ignition in gas turbine combustors. In this SBIR, we propose to develop an innovative analytical capability so that the combustordesigner can address operability issues. The key to predicting LBO/ignition is the use of time-accurate Unsteady Reynolds Averaged Navier Stokes (URAN ...
