A simulation tool is proposed to model and simulate the wind fields, turbulence fields, and the unsteady dispersion of NCBR substances in urban areas on the building to city blocks scale. This Computational Fluid Dynamics (CFD)-based approach has beenshown to accurately simulate the urban wind and turbulence fields with minimal approximations, and has been demonstrated by modeling the flow fields ...

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 ...

Conformal antennas for VHF/UHF have multiple uses, but the Phase I effort by Sciperio was focused on the design of a SLICE band omni-directional UHF antenna for integration within a soldiers helmet. The Phase I results for this conformal concept wereproof of the feasibility of designing an antenna capable of being integrated within or onto the surface of a Kevlar helmet. The antenna consists of ...

The objective of this Phase II proposal is to build, test, and deliver a programmable fiber-optic delay line capable of delaying an instantaneous bandwidth from 4 to 12 GHz from 0 to > 20 msecs, programmable in 10 nsec steps. The proposed delay line willimplement DWDM fiber-optic technology to minimize optical fiber while achieving an infinite capture time. A recent study involving an experiment ...

This Phase II SBIR will result in the design, fabrication and demonstration of advanced components for a semi-active RF sensor for the EKV of the Ground based Midcourse Defense System (GMDS). The baseline concept is derived from the results of the Phase ISBIR titled Concept Development and Assessment of a Multi-Mode Seeker for the NMD EKV. That effort identified the key technologies required to pr ...

A Phase II program is proposed to address fundamental technical and cost risks associated with the Segmented Launch Vehicle (SLV) concept. The SLV is an innovative, largely unexplored approach that will significantly reduce the cost of delivering cargo toLow Earth Orbit. A family of vehicles is being developed to service small (4,000lbm), medium (30,000lbm), and large (100,000lbm) commercial and G ...

Lewis Innovative Technologies, Inc. (LIT) has, under Phase I efforts, developed an electronic relay design capable of serving as a replacement for N-130 relays used on Navy CVN 68 class ships . To accomplish this, LIT has developed and utilizedproprietary techniques (Patent Pending) utilizing MOSFET technology to control alternating current power. In addition, LIT has developed monitoring/trigge ...

Department of Defense is interested in development of small fighter-like vehicle for combined underwater and surface motions at high speeds. The vehicle requires carry weapons under water. The weapons may generate high additional drag, and drag reductionis the key aspect in design of its hybrid hull. Hydrofoil removes missiles from water at highest speeds, but the problem is to reduce the drag bef ...

The objective of this Phase II SBIR proposal is to develop increased capability and fidelity in ground hazard estimation modeling following the interception by a directed energy (DE) weapon of a missile containing a chemical or biological payload. Thisincreased capability will be accomplished primarily through a set of experiments that will provide more stringent bounds on unitary chemical source ...

In order to destroy maneuvering ballistic targets containing chemical, biological or nuclear warheads by means of PAC-3 or THAAD like systems, the accuracy of intercept should be within centimeters from the targeted aimpoint. The twofold objectives of thePhase II research is to continue to develop, optimize and mature the new advanced GNC algorithms, including estimators/differentiators, guidance ...
