Optimize process to meet the specifications and challenges associated with the UH-1 tail boom. This will entail performing testing and evaluation of the factors deemed most relevant. This could include, but is not limited to material property testing, tooling design, tooling trials, in-situ process modifications, labor and fabrication cost analysis. Some of the specific topics that possibly pre ...

Applied Physical Sciences Corp. (APS) will develop a deployable marine mammal mitigation system. The system will use vector hydrophones to passively detect, track, classify, and localize vocalizing mammals. Wavelet and conventional spectral analysis methods will be coupled to species-specific tracking algorithms. Behavioral clues from the acoustic data will be used to further reduce false alarm ...

Existing multistatic airborne ASW systems require high power sources and are unable to exploit the significant forward scattering strength of a submarine target due to the blinding presence of the direct blast. Time reversal (TR) is a recent method for focusing acoustic energy at a point using pairs of source and receive arrays. The TR focus provides a measure of propagation channel stability, al ...

The overall intent of this project is to develop a series of vector sensors for thin-line submarine towed array applications and down-select one for full evaluation via a comprehensive test campaign. Once the sensor is perfected, a production run of eight sensors will be performed so that a thin-line towed array section can be fabricated and tested. Each vector sensor under consideration will co ...

The overall intent of this project is to develop a triaxial pressure-acceleration vector sensor that is suitable for reliable acoustic path sensing. The sensor is intended to have a nominal size that is commensurate with an AN/SSQ-53 DIFAR sonobuoy wet-end transducer, have a 6 km submergence depth rating, and exhibit a noise floor of nominally 40 dB re 1 micro-pascals-squared per hertz. This is ...

A fully coupled fire simulation and thermal-mechanical response and damage prediction tool will be developed by enhancing, packaging, and integrating our existing solution modules as an add-on tool kit for a commercial finite element solver such as ABAQUS. This tool will for the first time be able to model the fluid-structure coupled response of an advanced ship structure to a fire environment and ...

More than 1,300,000 Level 1 commercial vehicle inspections - a safety-critical, time-consuming, often difficult and painstaking process, especially as regards the brake inspection component -- are performed every year in the United States, under all sorts of weather and lighting conditions. The current technology used adds to the complexity and error potential inherent in this important task. In ...

In both the commercial and military electronics markets, there is a continuing trend to reduce size, weight, and overall equipment costs, while at the same time increasing functionality and improving reliability of the electronic circuitry. Integrated circuit manufacturers have addressed this need by integrating greater functionality directly onto the silicon chips, thus yielding the System-on-Chi ...

Precision Combustion, Inc. (PCI) proposes to develop a breakthrough Microlith short-contact-time catalytic steam reformer (CSR) system for reforming logistics fuels to hydrogen for a 50 kWe fuel cell. This technology offers to achieve high efficiency in steam reforming in a system that is remarkably smaller and more lightweight than current steam reformers. In addition water requirement should b ...

The further development of a hearing protection system is proposed that allows the user to listen to ambient acoustic sounds at safe levels---sometimes known as a "talk-through" system. The system exhibits high noise attenuation properties due to double hearing protection. Directivity and frequency response is preserved yielding a very natural listening experience. The system is fully wireless, an ...
