This project will investigate candidate space-time coding schemes to be incorporated in a multiple-input multiple output two-way communication system that operates within an urban warfare environment. The main objective is to increase channel capacity to achieve high-quality video transmission using narrow signal bandwidths, typically deployed for voice channels. The investigation will determine t ...

Advanced Cooling Technologies, Inc. (ACT), in partnership with the University of Nevada-Reno (UNR), is developing a high performance metal hydride heat storage and dissipation technology for high power lasers. The proposed technology incorporates heat pipes for passive acquisition and dissipation of high heat flux heat loads and metal hydrides for storage of the heat loads during the laser operati ...

Recent developments have made clear the strong potential of Micro Air Vehicles (MAVs) for a wide range of surveillance and tactical reconnaissance functions, particularly if the challenging but critical hovering capability can be achieved. Implementation of a practical hovering air vehicle at very small scales, however, requires breakthroughs in understanding of the complex flow environment of su ...

Boron has significant potential as a high energy density fuel in munitions and propellants. Its superior energy density makes it attractive as a fuel component in conventional solid propellants, as well as fuel slurries for ramjet applications. For a ramjet ducted rocket, theoretical density impulses of 1600-1800 sec-g/cm3 have been reported, 45% higher than the best hydrocarbon formulation. Bo ...

As part of the trend over the years of polymers replacing metals, substituting metallic wing skins with shape memory polymers (SMPs) that have excellent mechanical properties provides an opportunity to develop a new kind of morphing aircraft that can fulfil the needs of future military missions. Additionally, SMPs that can exert large recovery and regenerative stresses are needed for a broad range ...

ABSTRACT: The innovation proposed is a computationally-tractable, physics-based, portable turbulent combustion modeling strategy for application to a wide range of Air Force aero-propulsive systems, including augmentors, liquid rockets and scramjets. This modeling strategy will be implemented within an Application Programming Interface (API) library suitable for easy integration within Air Force ...

ABSTRACT: Due to scarcity of spectrum, Dynamic Spectrum Access (DSA) becomes a needed technology to improve the utilization of electromagnetic spectrum for DoD satellite communication. However, current DSA approaches are developed for terrestrial communications without addressing the unique challenges for SATCOM environments such as error-prone spectrum sensing, high mobility, and large coverage. ...

ABSTRACT: Coordinating and sharing information across multi-level security (MLS) networks are of great interest in many military applications. However, it is very challenging to accomplish those goals due to the heterogeneous security classifications of different network domains. The recent proposed cross-domain solutions (CDS) provide initial steps to make such applications possible. However, th ...

ABSTRACT: Global Engineering and Materials, Inc. (GEM) along with its team member Columbia University propose to develop a simulation tool for modeling mixing process of multi-particle composite systems and generating the ultimate microstructure. A combined theoretical, numerical, and experimental approach will be developed to create a high fidelity software product with a reduced order modeling ...
