The Navy continues to incur very high costs and lost service time due to unanticipated maintenance and repair or replacement of unreliable outboard sonar and other hardware on submarines, surface ships, minehunting systems and towed arrays. TRI/Austin will develop innovative new primer and potting compound materials to reduce water permeation, mitigate cathodic delamination failures, and to elimin ...

Navy operations in congested littoral areas or when transiting straits is very challenging for force protection because of heavy traffic ranging from small pleasure craft and fishing vessels, to very large cargo ships and barges that are navigating in close proximity. Constructing and maintaining the track picture over long periods of time under these conditions is particularly difficult because t ...

The primary objective of this effort is to develop a tractable computational tool to assess the probability of ignition within aircraft combustors and augmentors during routine igniter and/or system design analysis. This computational tool will provide for the off-line assessment of ignition probability given flowfield simulation data, characteristic igniter geometric and physical parameters, and ...

The arresting system is a critical component to ensure mission readiness and pilot safety during landing operations on an aircraft carrier. The Advanced Arresting Gear (AAG) Water Twister is the most critical mechanical component for absorbing kinetic energy from landing aircraft and as such it is necessary to ensure its reliability and health status. Issues have previously been identified with th ...

A Reactive Solids Tool concept will be developed which can be interfaced with a modern high-fidelity Computational Fluid Dynamics code to predict sand and ash behavior in high temperature combustor environments, and the potential for deposition of solid and molten particulate on gas turbine internal surfaces. This effort will utilize state-of-the-art knowledge of the material, chemical, morphologi ...

Neutron coincidence counters are currently based on 3H technology. A worldwide 3He shortage plus the need for significant improvements in performance necessitate the development of a new class of neutron detectors. We propose the use of boron-coated straw

A significant challenge in extracting event attributes from unstructured text is that events possess a wide array of attributes which affect decision making. In a single document, an author may describe events that have happened (realis), did not happen or could have happened (irrealis), and that may happen in the future. They may describe events which reflect a generic class of occurrences, or a ...

Tissue engineering technology is of particular import to the Army for the matter of producing tissue replacements for the repair and regeneration of various organ systems (liver, heart, muscle, lung, etc.) for wounded patients. Unfortunately, the production of masses of tissue with thicknesses greater than ~1 mm presents a challenge due to diffusion limits of nutrients into the tissue and waste ou ...
