This SBIR Phase I project proposes to develop an accurate viscous CFD algorithm which can include various small gaps between both static and moving components into the analysis. It is not an easy task to model those small gaps in the current CFD codes due to the geometric proximity, especially for moving components. However, those small gaps may have a significant impact on the aerodynamic, aeroel ...

It is proposed to development of a large-scale production apparatus that produces single-walled carbon nanotubes (SWNT) and catalytic multi-walled nanotubes (MWNT) on a continuous process basis. A novel and flexible reactor design will be investigated. Theproposed reactor design will allow the control of production parameters including catalyst type and particle size, the type of carbon source, ca ...

"The Phase I effort made significant headway in the understanding of the catalytic formation mechanism of carbon nanotubes (CNT's). Armed with this knowledge a systematic evaluation of potential processes for large-scale CNT production was undertaken. Theevaluation of arc, hot plasma, catalytic chemical vapor deposition (CCVD), and several production approaches determined that CCVD approach hold ...

This Small Business Innovation Research Phase I project develops a coupled computational aeroelasticity and thermal response analysis tool that can be used to analyze and design ballistic reentry vehicles and Trajectory Shaping Vehicles (TSV). In Phase I, a well validated thermal response analysis module will be integrated into a well validated computational aeroelasticity code. In Phase II, a gas ...

Safety Dynamics, Inc. proposes the development of an acoustic recognition platform that can identify and locate specific sounds related the breaching of perimeters and secured areas. The acoustic technology in question is novel, and is based on fundamental principles of neurobiological systems, i.e., it incorporates mathematical models and system architectures designed to mimic how the brain reco ...

ACTIVATED STEEL FOIL FABRICATED INTO ELEMENTS TO BE PACKAGED AS EXPENDABLE DECOYS HAS SHOWN GOOD PERFORMANCE IN LOW IR SIGNATURE APPLICATIONS. THE PRESENT BATCH PRODUCTION PROCESS FOR THESE FOILS ENTAILS, IN PART, TWENTY HOURS OF FURNACE TREATMENT. A COMBINATION OF NINE SEPARATE OPERATIONS, LOW PRODUCTION RATES AND HIGH LABOR COSTS YIELDS A UNIT MANUFACTURING COST OF MORE THAN $250.00. WE PROPOSE ...

Combustion instability, or screech, occurs in many modern gas turbine systems, and is due to the complex physical coupling of the acoustic resonances in the combustion chamber with fluctuations in the heat release of the combustion process. These instabilities can produce large pressure fluctuations that can be severe enough to damage engine hardware. Next-generation gas turbines will increase the ...

The primary technical objective of the proposed effort will be to investigate integration of optical gain medium with thin-film lithium niobate on insulator (TFLNOI) optical waveguides. Recent developments in crystal ion-sliced (CIS) TFLNOI have enabled a new class of electro-optic modulators and photonic integrated circuits with tighter mode confinement, a compact footprint, ultra-high bandwidth, ...

Active clearance control promises considerable improvements in rotating component efficiencies and compressor surge margin. These improvements are essential to meet stringent performance requirements for next generation propulsion systems. The improvements are more pronounced for small engines, because clearance effect in small engines accounts for a bigger portion of rotating component losses tha ...
