Current technologies for biodetection employ typically large, cumbersome, power-guzzling and expensive devices. Integration of separate sampler and detection units often poses problems. They are not flexible enough for adapting to different threatscenarios, and are not capable of monitoring for a variety of possible agents. CFDRC proposes to develop and demonstrate a Microfabricated, Electro-immun ...

Elimination of high pressure and cryogenic propellant storage and feed systems for undersea vehicle fuel cells is of interest to the Navy. CFDRC proposes the development of a rechargeable oxygen generator based on microwave plasma decomposition ofsolid-state lithium perchlorate. The generator will employ the atmospheric microwave plasma torch technology recently demonstrated by the Plasma Science ...

In high F/A military gas turbine combustors such as JSF, localized pockets of carbon monoxide (and perhaps hydrogen) can exit the combustor, causing severe cooling challenges for designers of turbine inlet guide vanes. Instead of cooling the vane, coolingair can actually interact with the hotpath flow to release heat near the vane surface, resulting in catastrophic damage. In this SBIR, we propose ...

Monte Carlo simulations of rarefied gas dynamics are important for many applications. This project aims to substantially accelerate Monte Carlo (MC) algorithms and develop a rigorous and efficient computer code applicable for a wide range of Knudsen numberfrom rarefied to continuum flow regimes. This will be achieved by using implicit treatment of the collision processes, majorant frequency scheme ...

This proposal offers an innovative and efficient computational simulation tool for the prediction of missile plume transient events and associated missile unsteady flow fields. The proposed solution will enable simulating the complete range of flowfieldtransient effects resulting from time-dependent flow boundary conditions, prescribed body and thrust vector motion, and up to performing a complete ...

Simulation of time-dependent rheological behavior in an advanced Computational Fluid Dynamics (CFD) environment revealed that inclusion of a structural parameter within a modified empirical power law expression is capable of predicting the flowcharacteristics of thixotropic gels. Validation of the CFD based predictions was completed using a combination of published AMCOM test data and thixotropic ...

Reliable and sensitive aerial defense applications (missile seekers, avionics, remote sensing) demand that electronic components be resistant to ionizing radiation from nuclear weapons and upper atmosphere/terrestrial sources. CFDRC, in collaboration withHoneywell and Vanderbilt University, is proposing to develop electronic-hardening concepts at the process, device and primitive cell level to ach ...

The project objective is to develop an integrated, hierarchical, multi-resolution tool for comprehensive prototyping and evaluation of new propulsion systems together with the launch vehicle systems. The overall vehicle system and its adjuncts will betreated as a collection of interacting software components coupled by a computational environment. Full and reduced scale component modules will al ...

CFD Research Corp. proposes the development of an Advanced Multipurpose Pseudospark Switch (AMPS) e-beam source capable of efficiently generating high average/peak current, bright electron beams. The improvement in e-beam quality (over a classicalpseudospark) stems from the inductive preionization of the hollow cathode chamber, prior to main gap breakdown. The proposed device features similaritie ...

Infrared image generation for IR sensor development and testing are currently large workstations costing several hundreds of thousands of dollars. Performance and image resolution is the key limiting factors of using PC hardware for this task. Usingdistributed processing, and intelligent algorithms, along with the forthcoming advances in PC graphics hardware; the next generation of real-time image ...
