  1. Naval Device Applications of Relaxor Piezoelectric Single Crystals

    SBC: Btech Acoustics, LLC            Topic: N02066

    This project is the development of a single crystal underwater acoustic modem transducer for Unmanned Underwater Vehicles (UUV) which is compact in size, operates at low to moderately low center frequencies, in a broad band frequency range to accommodate state-of-the-art binary, FSK and spread spectrum signaling schemes that promote covertness. The device exploits the high coupling coefficient an ...

  2. Validation Tools and Data for PHM Technologies

    SBC: SENTIENT CORPORATION            Topic: N04028

    Development of accurate and effective new diagnostic and prognostic capabilities for JSF PHM will require extensive data on both health and faulted systems states. While healthy signatures can be collected quickly and easily, faulted systems are only observed rarely, and duplicating faulted conditions with seeded fault tests is time-consuming and expensive. Simulation models for faulted conditions ...

  3. Physics-based Modeling of Acoustic Reverberation in the Littoral Environment

    SBC: Marine Acoustics, Inc.            Topic: N03T011

    Underwater acoustic modeling plays an essential role in the design, development, test, and operation of sonar systems. Active acoustic clutter can increase the sonar false alert rate or equivalently decrease the probability of detection/classification, and is a key issue in the development and utility of active sonar systems. The ability to predict reverberation and clutter is inseparably tied to ...

  4. Effective Diagnostics for Dynamic Operating Environments

    SBC: SENTIENT CORPORATION            Topic: N05104

    Fault detection and isolation algorithms are often developed with data from steady-state tests, and many algorithms perform well under these controlled conditions. However, when diagnostics are used in highly dynamic environments, sensitivities to changing loads or speeds become apparent. Vibration metrics tend to be particularly susceptible to operating condition variations. This sensitivity inte ...

  5. Innovative Materials/Concepts for Grease Lubricated Bearings

    SBC: SENTIENT CORPORATION            Topic: N05089

    Grease lubricated bearings are widely used in aircraft for driveshaft support, fans, and accessories. These components are a maintenance intensive item requiring regular replenishment or replacement. In addition, occasional failures occur and have resulted in loss of aircraft. Sentient Corporation, in collaboration with SKF/MRC bearings and Sikorsky Aircraft, will study and address the dominant fa ...

  6. Embedded Health Monitoring for Propulsion Control System Actuators

    SBC: SENTIENT CORPORATION            Topic: N05094

    The latent degradation of precision control system actuators affects dynamic performance and can push the performance characteristics of the actuator out of the regime needed for stable operation of the aircraft control system. Current system-level methods are not sensitive enough to actuator degradation and have no ability to isolate the fault to a specific sub-component or provide an estimate o ...

  7. TAC PROPOSES TO CONDUCT A STUDY TO EVALUATE THE COMPARATIVE EFFECTIVENESS OF VARIOUS FORWARD-LOOKING AUTONOMOUS SENSORS AND ALGORITHMS FOR TLAM-C.

    SBC: The Associated Corp            Topic: N/A

    TAC PROPOSES TO CONDUCT A STUDY TO EVALUATE THE COMPARATIVE EFFECTIVENESS OF VARIOUS FORWARD-LOOKING AUTONOMOUS SENSORS AND ALGORITHMS FOR TLAM-C. THE CURRENT TLAM-C USES A TERRAIN MAPPING RADAR ALTIMETER AND CORRELATES THE SENSED AREA AT KEY WAYPOINTS WITH A STORED DIGITAL REPRESENTATION OF THE TERRAIN AREA AT THE WAYPOINTS TO PROVIDE MID-COURSE AND TERMINAL GUIDANCE CORRECTION TO THE INERTIAL NA ...
