ABSTRACT: Optical Sciences Corporation (OSC) and the University of Alabama in Huntsville"s Center for Applied Optics (UAH/CAO) will demonstrate the feasibility and present a plan for developing optical instrumentation for the monitoring, mitigation, and removal of cryodeposits accumulated on optical and mechanical surfaces in cryogenic-vacuum radiometric calibration chambers. OSC will investigat ...

ABSTRACT: We propose development of an efficient physics-based computational capability for real-time radar location of targets in cluttered environments. Our effort will focus, in particular, on air traffic targets in static natural environments that include dynamic effects such as spinning wind turbines. The proposed methodology models radar signal scattering in cluttered environments on t ...

The project will remove a key difficulty that currently hampers many existing methods for computing unsteady electromagnetic waves on unbounded regions. Numerical accuracy and/or stability may deteriorate over long times due to the treatment of artificial outer boundaries. We propose to develop a universal algorithm and software that will correct this problem by employing the Huygens'principl ...

ABSTRACT: Stability phenomena that are of vital interest in liquid rocket motor development involve a confluence of diverse physics and interactions across many system components. Any comprehensive, self-consistent numerical model is burdened by a very large computational mesh, stiff unsteady processes which limit permissible time step, and the need to perform tedious, repeated calculations for a ...

ABSTRACT: NextGen Aeronautics Inc. proposes use of rapid prototyping (RP) technologies, design process improvements, and novel sensing technologies to significantly reduce time and cost of transonic aeroelastic wind tunnel model development and improve their direct correlation to CFD data. The use of modern RP technologies will allow for model design variations such as variable modulus (stiffness ...

ABSTRACT: Adversarial installations, such as those housing the means for nuclear weapons production, are increasingly being constructed in heavily fortified locations and often using ultra high performance concrete (UHPC) as the construction material. As such, the U.S. Air Force has considerable interest in further developments of ultra high performance concrete (UHPC) to maintain an advantage o ...

ABSTRACT: Experimental testing of dynamic models has been performed for more than 50 years and a wealth of data exists for individual models. However, this data is often either restricted as proprietary or is not suitable for CSE tool validation as a result of incomplete model or test information. Mainstream Engineering proposes to design, fabricate, and test a scaled fighter for aeroelastic ...

ABSTRACT: Under this collaborative effort, Creative Aero Engineering Solutions (CAES) and its academic partner University of California Los Angeles (UCLA) are pleased to team on the research entitled"Scaled Transonic Dynamic Aeroelasticity through Wind Tunnel Testing (ST-DAWTT),"consisting of a novel approach for characterizing the transonic aeroelastic environment of a full-scale fighter in the ...

ABSTRACT: Tanner Research, Inc., in collaboration with University of Maryland, will determine feasibility and plan for development of technology based on insect visual sensing and processing, which will integrate three modes related to navigation and guidance: motion detection from imaging sensing; polarization sensing and processing to implement a celestial compass; and ocellar sensing and proce ...

Lithium-air battery consists of a lithium anode electrochemically coupled to atmospheric oxygen through an air cathode. The major advantages of lithium air batteries are that air cathode active material, oxygen, is not stored internal to cell system and lithium anode being extremely lightweight metal with a highest theoretical specific energy density. This energy density is well comparable with t ...
