The SKATE concept was designed to quantify skill levels of trainees, teams, or units, generate skill-appropriate training scenarios, and provide a continuous skill-level assessment of disparately skilled trainees, teams, and units in a joint training exercise while maintaining the overall integrity and realism of the mission itself. SKATE evaluates the skill level of an individual, teams, or unit ...

Applied Physical Sciences and the University of Maryland propose to develop a magnetostrictive transducer that harvests electrical energy from shipboard machinery while simultaneously suppressing vibration to improve the ship’s stealth characteristics and thereby improving the performance of hull mounted sonar systems. Analysis performed during the Base Effort will provide an initial design spec ...

Applied Physical Sciences (APS) and the Pennsylvania State University Applied Research Laboratory (ARL/PSU) will collaborate in the development of a novel sensor system to measure the low frequency acoustic pressures within a fluid-filled pipe. The proposed concept improves upon the Navy’s current Array Based Acoustic Measurement (ABAM) system for laboratory characterization of full-scale piping ...

Energy harvesting devices utilizing magnetostrictive materials are a logical choice for harvesting the high impedance (high force, low displacement) vibrations found aboard Navy ships. Force-based devices, enabled by magnetostrictive materials, can harvest energy over an extremely large bandwidth, approximately ±35 and ±70 Hz currently, making them more desirable in situations aboard Navy ships ...

A software tool for fracture evaluation and load deflection prediction of welded aluminum ship structures subjected to impulsive loading will be developed by enhancing and integrating an existing extended finite element method (XFEM) for dynamic fracture of thin shells in Abaqus. The software package will be able to model arbitrary crack paths as dictated by the physics of the scenario, completely ...

This Small Business Technology Transfer Research (STTR) Phase II proposal from Materials and Systems Research, Inc. (MSRI) and University of Utah (research institution) seeks to fabricate single-phase, polycrystalline tungstate ceramics with densities greater than 99.95% and a mean grain size of less than 1 um. These ceramics have been chosen because of their low thermal expansion and low elastic ...

Free-play nonlinearity of the control surfaces has a direct impact on aircraft’s dynamic stability characteristics. . It is impossible to design and manufacture a control surface with zero free-play. As control surface free-play increases, tighter limits must be imposed on the aircraft mission capability. Typically, researchers have utilized an oversimplified piecewise-linear torque-rotation rel ...

The proposed effort leverages the capabilities of data-driven and physics of failure (PoF) based prognostic techniques for electronic systems by combining them within a hybrid approach. Data-driven and PoF-based techniques both have shortcomings; combining them into a hybrid framework allows using their capabilities in a complementary fashion, and thereby providing a reliable way of prognostics an ...

The primary objective of the proposed effort is to develop a validated computational tool to predict the afterburning of non-ideal munitions containing metal and hydrocarbon fuels. The activities outlined devise a well-coordinated collaboration among researchers from Reaction Engineering International (REI) and the State University of New York at Buffalo (UB). The activities proposed will build on ...

Investigations into JP-10 combustion chemistry thus far can be characterized as preliminary. The detailed chemical kinetic mechanisms that have been published are limited in their ability to reproduce experimental data. The combustion chemistry of JP-10 is highly complex, involving hundreds if not thousands of species and thousands of chemical reactions. A detailed kinetic model capable of predict ...
