  1. High Fidelity Helicopter Lag Damper Model for Comprehensive Rotor Analysis


    This research is dedicated to developing high fidelity lag damper models to significantly improve the accuracy of the analysis of the rotor lead-lag damper forces over a wide range of blade lead-lag motion amplitudes, temperatures, and frequencies in support of aircraft design and engineering applications. The model development will emphasize the dampers with various configurations (e.g., linear ...

  2. High Resolution Measurement of the Flow Velocity Field in a Supersonic Jet Plume


    Modern supersonic jet aircraft engines produce a high amplitude noise field with complicated characteristics due to turbulent behaviors of the hot jet. Researchers need better understanding of the turbulent structures in the jet plume to develop treatments to engines that might reduce the noise emissions. A significant obstacle to making these simulations practical and realistic for engine design ...

  3. Highly-controllable, Dense Carbon Nanotube Arrays for Ultracapacitor Applications

    SBC: ADA Technologies, Inc.            Topic: OSD10T004

    The Navy and the U.S. Military as a whole will be challenged to find innovative solutions to ever-rising peak power demands stemming from the introduction of electricity-driven vessels and new directed energy weapons in the coming decade. Circuit protection from voltage variation is also a concern both on large and miniaturized scales. To address these needs, ADA Technologies, Inc. (ADA), in colla ...

  4. Image Feature Extraction for Improved EW Classification

    SBC: Arete Associates            Topic: N11AT015

    The proliferation of inexpensive radar and communication devices has complicated the target identification problem for modern submarine EW systems. Arete Associates and ARL Penn State propose real-time software called Submarine Multi-Sensor Automatic Target Recognition (SMS-ATR). The approach leverages existing periscope imaging ATR algorithms to allow rapid integration of EW intercept data for ro ...

  5. Innovative Application of Urban ISR (Intelligence, Surveillance, Reconnaissance) Imagery for High Fidelity Training Devices

    SBC: CG2, Inc.            Topic: N09BT038

    The hindrances to full use of geospecific imagery are the labor required to create the databases, and limits on the rendering capacity of current image generators (IGs), both in polygon count and texture volume. Our solution is to create modeling tools to automate the application of ISR imagery on geospecific urban geometry and to use advanced rending techniques to visualize dense urban scenes in ...

  6. Large Eddy Simulations of Hot Supersonic Jets for Aeroacoustics

    SBC: CASCADE TECHNOLOGIES, INC.            Topic: N09T008

    LES will be used to calculate flow and noise issuing from realistic engine configurations such as realistic engine nozzle throats, serrated nozzles, straight ramp diffusers, and over/under expanded operation. Nozzle geometry and operating conditions can be specified by the government with the objective of validating noise prediction capability on the basis of realistic parameters. Where necessary, ...

  7. Low Cost and Safe Li2MSiO4 Cathode Materials for Pulsed Power Applications

    SBC: Chemat Technology, Inc.            Topic: N11AT035

    EM Railgun project in Navy demands safe, high energy and long cycle life Li-ion batteries. In this Phase I research, we will demonstrate the feasibility of Li2MSiO4 cathode materials for this application. Special thin coatings will be self-assembled on the nanosize particles to significantly improve the performance to achieve high capacity (>200 mAh/g) at>4V with extended cycle life. The sol-gel c ...

  8. Micro-Plasma Turbulence Velocimetry (uPTV)

    SBC: Wavefront            Topic: N11AT004

    Non-invasive methods are required to measure the turbulence in supersonic jet plumes in 3-D with high temporal and spatial resolutions. The turbulent supersonic jet plume changes rapidly both in space and time, and hence any viable approach must acquire the entire 3-D velocity field at even faster speed for comparison with the temporal and spatial velocity field solved in Large Eddy Simulations. ...

  9. Miniature Electromagnetically Controlled Assembler Robot Swarm: MECA-BOTS

    SBC: Arete Associates            Topic: N11AT037

    Arete Associates, in collaboration with the NanoRobotics Laboratory of Carnegie Mellon University, plans to design and demonstrate a desktop-sized assembly system utilizing a coordinated team of micro-robots. Called MECA-BOTS (Miniature Electromagnetically Controlled Assembler Robot Swarm), this system will be used to construct items and materials of interest to the Navy and the DoD. The micro-rob ...

  10. Modeling of pulse propagation in a four level atomic medium for gyroscopic measurements

    SBC: ROCHESTER SCIENTIFIC, LLC            Topic: N11AT005

    Precise rotation sensors are critical components for stabilization, navigation, and targeting applications. The most sensitive commercial devices are fiber optic gyroscopes based on the Sagnac effect. There is the potential to enhance the performance of these gyroscopes using media with large positive (''slow light') or negative (''fast light') dispersion. In order to ...
