  1. Improving the Physics of Applied Reverberation Models

    SBC: ADAPTIVE METHODS, INC.            Topic: N13AT026

    The proposed effort will enhance the capability of the Acoustic System Performance Model (ASPM) and its implementation of the ASEPS Transmission Loss (ASTRAL) model by adding to it a treatment of several physical phenomena. Research in recent years has demonstrated that sea surface forward scatter consists of coherent and incoherent components with both having profound impact on reverberation. The ...

  2. Innovative Unified Damage Mechanisms-Based Model to Predict Remaining Useful Life for Rotorcraft Structures

    SBC: TECHNICAL DATA ANALYSIS, INC.            Topic: N14AT002

    Recent studies by the PI and the Co-PI of this STTR effort have shown that aluminum alloys and stainless steel in Low Cycle Fatigue (LCF) fail upon reaching a critical entropy; claimed to be an intrinsic material property. The critical entropy has been used as damage metric for prediction of remaining useful life (RUL). Also, similar entropic concept has previously been applied to LCF of composite ...

  3. Situational Awareness as a Man-Machine Map Reduce Job

    SBC: DECISIVE ANALYTICS CORPORATION            Topic: N13AT024

    This effort is focused on the development of a system called Situational Awareness via Mixed-initiative Universal Recognition, Analysis, and Inference (SAMURAI). SAMURAI will provide a single cloud-enabled end-to-end workflow covering the full range of data analysis from data ingest to situational assessment and decision support. As part of this workflow SAMURAI will provide the ability for automa ...

  4. Developing and validating a model to understand mixed lubrication regions for fluid-film bearings

    SBC: Xdot Engineering And Analysis, PLLC            Topic: N12AT010

    Seawater lubricated propulsor (i.e., stern tube) bearings are one of the most important bearings aboard a ship. The performance and life of these bearings directly affects the vessel's operational capabilities, life cycle costs, and overall availability. In a single shaft vessel such as an Ohio class SSBN, any failure of this bearing is extremely problematic. In certain applications such as submer ...

  5. Compact robust testbed for cold-atom clock and sensor applications

    SBC: Coldquanta, Inc.            Topic: N13AT018

    Our goal in this Phase II effort is to construct and test a compact, robust testbed for generating laser-cooled strontium atoms on a mobile platform. The focus of the Phase I effort was designing and fabricating an ovenized strontium source that also serves as a 2D+ MOT cell. In Phase II, we will integrate the strontium source into an all-glass-and-silicon vacuum system maintained by a miniature i ...

  6. Flight-Certified Lithium-ion Battery

    SBC: PROGENY SYSTEMS CORPORATION            Topic: N15AT001

    Progeny Systems Corporation and University of Colorado Colorado Springs team proposes to develop Naval Aviation Flight-Certified Lithium (LI)-ion Battery (NAFCLiB) to provide a safe, reliable, modular and scalable high energy density, long life, low self-discharge battery pack monitored by a robust physics-based battery management system (BMS) suitable for flight certification and employment on N ...

  7. Novel Multi-scale/Multi-physics Integrated Tool for the Prediction of Manufacturing-Induced Defects in Autoclave Composite Airframe Parts

    SBC: TECHNICAL DATA ANALYSIS, INC.            Topic: N15AT003

    Composite materials have emerged as the materials of choice for increasing the performance and reducing the weight and cost of military aircraft. Nevertheless, manufacture of composite parts still poses numerous difficulties which can result in premature curing, degradation in thin cross-sections, incomplete curing in thick counterparts or build-up of internal stresses. Experimental investigations ...

  8. Innovative Physics-based Modeling Tool for Application to Passive Radio Frequency Identification System on Rotorcraft

    SBC: Applied EM Inc.            Topic: N15AT005

    Tracking dynamic components of rotorcraft is crucial to component life assessment and overall fleet management. The Navy is pursuing an effort to collect the component information directly off the aircraft through the use of passive RFID (pRFID) tags and a novel reader/gateway system to communicate with the ground station. Finding an optimum pRFID tag/antenna reader system arrangement without a co ...

  9. Towed Magnetic Anomaly Detection (MAD) Aerodynamic Modeling and Simulation for Rotary Wing Platforms

    SBC: Area I, Inc.            Topic: N15AT009

    The Area-I team proposes to leverage its expertise and extensive design, analysis, and simulation tools to evaluate the design space of towed magnetic anomaly detection (MAD) systems with the goal of understanding the design trends and requirements in developing a new, lightweight rotorcraft-towed anti-submarine warfare (ASW) system that is optimized to take advantage of smaller state-of-the-art M ...

  10. Experimental Noise Measurement System for Ship Sonar Design

    SBC: ADAPTIVE METHODS, INC.            Topic: N15AT015

    Hull mounted sensor arrays are an important tool used to determine localized threat assessment. The location of these arrays on the ship is critical. They must be placed at the quietest location on the hull to minimize own-ship noise which can interfere with array sensitivity. To determine these quiet locations, Adaptive Methods has proposed incorporating vector sensing modules which can be tempor ...
