  1. Matched Filter Chaos Communications

    SBC: TORCH TECHNOLOGIES INC            Topic: A11aT002

    A plan is presented to demonstrate the feasibility and practicality of a radio-frequency Hayes-Corron (H-C) chaos-based communication system employing an optimal spread-spectrum chaotic communication theory to achieve superior low-power, low-probability of interception, multiple-user access, and portability goals. By integrating three concepts: 1) chaotic spreading sequence generation, 2) Hayes en ...

  2. High Fidelity Obscurant Modeling for Sensor Simulations

    SBC: Gleason Research Associates, Inc.            Topic: A11aT004

    A particle-systems approach is proposed for rendering obscurants in tactical missile scene generation. Obscurants are currently rendered using arrays of voxels, small homogeneous cubes containing concentration and temperature data. Voxels have been highly successful but they require huge data files and are very slow to render. The particle systems would not replace voxels for high-fidelity applica ...

  3. High Fidelity Obscurant Modeling for Sensor Simulations

    SBC: SIMULATION TECHNOLOGIES, INC.            Topic: A11aT004

    A technique that enables new methods of obscurant modeling with faster rendering while maintaining or improving physical fidelity is proposed. the proposed technique not only exhibits the qualities of voxel based obscurants, but matches real-world data as well. The main objective from Phase I efforts will be a specification for the technique of generating physically correct and efficient obscuran ...

  4. A Priori Error-Controlled Simulations of Electromagnetic Phenomena for HPC

    SBC: COMPUTATIONAL SCIENCES LLC            Topic: A11aT015

    The project will remove a key difficulty that currently hampers many existing methods for computing unsteady electromagnetic waves in unbounded regions. The accuracy and/or stability of the simulations may deteriorate over long times due to the treatment of the outer boundaries via artificial boundary conditions. We propose to develop a universal algorithm and software that will correct this probl ...

  5. Dual Fuel Use of JP-8 and Hydrogen for Improved Compression Ignition Engine Performance

    SBC: STREAMLINE AUTOMATION, LLC            Topic: A11aT023

    With the advent of more efficient hydrogen reforming systems, a practical hydrogen source has lead to investigations on the operating characteristics of diesel (JP-8) engines with a hydrogen/syngas additive. Several sources have reported that higher thermal efficiencies and lower pollution occur when hydrogen is added to the fuel stream. The objective of this proposal is to experimentally quanti ...

  6. Improve pyrotechnic smoke formulations that produce low flame

    SBC: Polaris Sensor Technologies, Inc.            Topic: A11aT026

    The objective of this research is to develop materials that may replace the current generation of visible smoke formulations used by the U.S. military. In particular the materials must produce low flame so that they do present a fire hazard, have relatively low toxicity, and are efficient. The efficiency is defined in a figure of merit that combines fill factor, yield factor, extinction coeffici ...

  7. Fast Algorithms for Generating Hardbody Thermal Histories

    SBC: AEGIS TECHNOLOGIES GROUP, INC., THE            Topic: MDA10T003

    The AEgis Technologies Group proposes to develop an innovative real-time thermal solver solution to model hardbody thermal histories. This thermal solver solution will consider the relevant phenomenology associated with MDA targets and other associated objects requiring thermal histories. Modeling of complex objects and advanced features such as model ablation and dynamic surface areas will be co ...

  8. An Accurate 3D Real-Time Simulation Tool for Generating Hardbody Thermal Histories

    SBC: CFD Research Corporation            Topic: MDA10T003

    Existing thermal analysis tools for optical signature generation are employed in an off-line manner, and are inadequate for new closed-loop real-time system simulations being pursued by MDA. This STTR project aims to develop and demonstrate an innovative simulation tool for the automatic generation and subsequent computation of reduced thermal models for accurate, real-time analysis of complex 3D ...

  9. Physics Based Modeling Tools for Next-Generation Lithium Ion Battery Performance and Lifetime

    SBC: CFD Research Corporation            Topic: MDA10T004

    The MDA is developing satellite based systems that could benefit from ongoing developments in advanced materials for lithium ion batteries. Unfortunately, the driving applications for much of the new materials research have less abusive operational cycles than the frequent cycling, and sporadic pulse loads to deep discharge, of MDA satellite applications. Physics based models of battery performa ...

  10. Highly-Scalable Computational Algorithms for Solving Aerostructural FSI Problems on Emerging Parallel Machine Architectures

    SBC: CFD Research Corporation            Topic: AF10BT13

    ABSTRACT: Traditional multidisciplinary solvers function by solving the individual governing equations on computer clusters. In the case of aero-elastic Fluid-Structures Interaction (FSI) simulations, individual solvers have disparate requirements for optimal performance. CFD codes use iterative schemes and distributed memory, while CSD codes, use direct linear-solvers and utilize shared memory t ...
