This SBIR Phase I will formulate and test a metal/WS2 Composite Dry Film Lubricant.The variables which will affect the result are the carrier gas temperature, the impact velocity on the substrate and the ratio of WS2 to metal.Three different metals are being explored to increase chances of success. Harder, higher melting point metals like Ti64 are more challenging for the Cold Spray technique, but ...

The fusion welds of dissimilar refractory metals suffer from many limitations including shrinkage cavities, solidification cracking, embrittlement due to impurities, inferior strength and ductility, increased fabrication cost etc. GenNext Materials and Technologies, LLC proposes to develop dissimilar refractory metal friction welds for fabricating hollow cathodes free from these limitations.nbsp;n ...

Ground-based sun photometers provide an important consistent global long-term aerosol data record that is used to better understand aerosol impact on climate, improve aerosol transport models and bound lidar-derived aerosol products. Since sun photometers only provide aerosol information during the day, even thoughnbsp;there is scientific interest, there is very little information on aerosols at n ...

Small satellites such as CubeSats are in need of responsive propulsion, but are limited due to their size. Though single pulse, AP/HTPB fueled solid rocket motors exist in the market, greater mission flexibility is to be had from a motor with the capability of a second ignition in the same volume constraints. Digital Solid State Propulsion (DSSP) proposes research into the technology to not only t ...

A recent breakthrough in combustion stability analysis (UCDS) offers the means to accurately predict the combustion stability of a scramjet. This capability is very important due to the extreme scramjet operational environment, which makes cut-and-try development approaches impractical. With UCDS, it is now possible to accurately predict the scramjet pressure oscillation amplitudes, along with c ...

Cities must perform detailed assessments of sidewalks and streets, including curb ramps, pedestrian signals, crosswalks, street furniture, and other components to determine compliance with the Public Rights-of-Way Accessibility Guidelines. However, current assessment methods are inadequate or unreasonable due to time and resources required. The objectives of this project are to: 1) develop elect ...

In the Open-source microscopic traffic simulation models project, a component based software framework is proposed to re-engineer CORISM data struture and CORISM interface. Under the architecture combing the innovative framework and the legacy CORISM, prototype of the open source traffic flow simulation models will be developed and demonstrated in the Phase I. In addition, areas identified by th ...

THE PRIMARY PURPOSE OF THIS PROJECT IS TO REDUCE THE REQUIREMENTS FOR INITIAL ALIGNMENT ACCURACY WHEN BRINGING A PAIR OF CONNECTORS TOGETHER PRIOR TO MATING THEM. THIS WILL BE ACCOMPLISHED BY INVESTIGATING THE USE OF A TAPERED OR CONICAL DESIGN TO INCLUDE A PRELIMINARY LATCHING FEATURE TO CAPTURE AND TO CAUSE ALIGNMENT OF A PAIR OF COMPLEMENTARY CONNECTORS. THE INVESTIGATION WILL TAKE INTO CONSIDE ...
