Despite advances in automated instruction, virtual environment (VE)-based shiphandling trainers still significantly depend upon expert mariners, with individual instructors typically working with only a single active student at a time. This bottleneck makes it difficult to realize the full benefit of VE training systems. Promising support technologies, such as the Conning Officer Virtual Environme ...

Rechargeable lithium ion battery systems can provide power throughout the aircraft, including engine or Auxiliary Power Unit (APU) starting, avionics, emergency, and other systems. Because of their high specific energy/power and potential thermal instability, they can present hazards if improperly designed, tested, handled, or stored. To address the thermal safety issue of Li-ion batteries, EIC La ...

TeraDiode is developing a low Size, Weight, and Power (SWAP) multi-band MWIR/LWIR laser module for NAVSEA under SBIR funding. TeraDiode is employing high power Quantum Cascade Laser (QCL) bars in this laser module and WBC to combine the multiple wavelengths. The laser module is very compact and has three wavelength bands in the MWIR and LWIR as well as high power per band (>10 W per band average p ...

ABSTRACT: ASTM standards exist currently to characterize various combustion characteristics of flammable chemicals such as flammability limits, flash point, minimum ignition energy, and auto ignition temperature. There are no such well-accepted characterization protocols for hot surface ignition temperature measurements. This is partly due to a large variation in the (i) test setups used in the li ...

During the course of this proposed Phase II program, Metamagnetics Inc. will continue the efforts toward development of a compact solid-state High Power Radio-Frequency (HPRF) source by building upon the results obtained from our Phase I effort, whereby a proof-of-feasibility demonstration of an innovative c (NLTL) for the generation of HPRF signals was achieved.This proposed system will be capabl ...

Defending against state-of-the-art cyber attacks such as Advanced Persistent Threats requires rapid, automated, and accurate prioritization of cyber alerts to provide timely and comprehensive cyber-situational awareness. Context Aware INference for Advanced Persistent Threat (CAIN for APT) will address this important operational need by developing, evaluating, and transitioning our innovative case ...

Marine Expeditionary Units (MEUs) are often first responders, addressing crises such as natural disasters and regional instability. Crowdsourcing provides a powerful potential tool to help MEU analysts collect and analyze information in new operational settings, but Marines need tools to manage crowdsourcing. MapReduce addresses a similar distributed parallel processing problem, without the divers ...

ABSTRACT:During a Phase I effort, Physical Sciences Inc. (PSI) successfully developed a nonflammable ionic liquid (IL) based electrolyte that can be used as a drop in replacement in commercial cells for Air Force applications. The proposed program will continue to optimize the performance of this electrolyte and demonstrate the ability to construct safer Li-ion pouch and cylindrical cells. During ...

ABSTRACT:The damage tolerance approach is used widely in the aerospace industry and has a physics-based foundation in fracture mechanics. The fatigue crack growth rate can be determined by calculating the SIF (stress intensity factor) and knowing empirically derived material parameters. Similitude is achieved for different loads, different crack sizes, and different crack shapes. The down side to ...

Plain, self-lubricating spherical bearings operating in high levels of airborne abrasive contaminant particle environments, such as desert regions, are subject to accelerated wear of their PTFE (Polytetrafluoroethylene) liner systems. Accelerated bearing wear has been observed in fielded aircraft and leads to increased maintenance costs, Flight Safety Risk and reduced operational availability. The ...
