High-fidelity representation of terrain morphology is a critical requirement for accurate modeling and simulation of infrared background scenes. The current state of the art in terrain representation for missile seeker systems and other military applications is based on digital elevation models, which are relatively coarse in resolution and have smooth contours that do not resolve the presence of ...

Both the Deep Skirt and Advanced Skirt System material used on Landing Craft Air Cushion (LCAC) experience significant wear during normal operations, which require expensive, time-consuming maintenance repairs. The US Navy is looking for innovative new material and manufacturing method for skirt systems to improve it durability and reduces Total Ownership Cost (TOC). Rubber skirts experience two m ...

Upgrades to the E-2D Advanced Hawkeye inadvertently resulted in higher acoustic loading at its propellers blade pass frequency (BPF). This frequency overlaps with vibrational modes of the standard fixed-wing aircrew helmet, the HGU-68/P. As a combined result, E-2D pilots are experiencing exceptionally large vibrational and acoustic (noise) loading, potentially compromising aircrew performance and ...

Traditional manufacturing methods for producing warheads, propellants, and pyrotechnic systems are timely and costly. Additive manufacturing (AM) approaches offer one path of alternative manufacturing technologies. Among various technologies, powder bed fusion (PBF) is one promising approach. Hewlett Packards Multi-Jet Fusion printers utilize a unique PBF process that presents a desirable solution ...

Navy vessels, along with other military, civil, and commercial equipment and structures, are routinely stripped by abrasive blasting in preparation for re-coating. Using existing nozzles, blasting generates continuous noise levels up to 145 dBA, and even with correctly worn double hearing protection, blasting operators are at risk of hearing damage. Noise induced hearing loss has become the most c ...

Hyperbaric and hypobaric environments are known to have profound effects on the physiology of animals and humans. These effects can limit mission capabilities or, in some cases, even be life threatening. In other cases, these environments can induce very beneficial, sometimes life saving health effects. Even though the health effects of hypo/hyperbaric exposure have been observed for many decades, ...

Scientific Solutions, Inc. (SSI), teamed with BAE Systems and Southall Environmental Associates, Inc. (SEA), proposes to investigate the feasibility of using commercially available active sonar to autonomously identify and track marine mammals from transiting SURTASS-LFA surface ships at ranges out to and beyond 2,000 yards. Active sonar has been proven effective to detect and track marine animals ...

Chemiresistors are an important class of electronic sensors that detect the presence of analytes/chemicals via a change in the resistance of a sensor element. A typical interdigitated electrode array is deposited onto an insulating substrate with metallic electrodes that have feature sizes in the 5-500 m range. The metal electrodes are typically sputter coated onto the substrate, using lithogra ...

Solid oxide fuel cells have long suffered from degradation due to impurities in the fuel and complexities associated with dissimilar materials and high operating temperatures.This degradation lowers the usable cell power output and requires ancillary equipment for fuel sulfur removal and reformation.A unique microstructure for the tubular anode will be produced using a novel freeze-casting techniq ...

Responsible waste disposal has become an important challenge as the world population has grown, concern about the environment has increased, and energy costs have risen. Landfills are unsustainable and have potential to contaminate groundwater, while incineration consumes fuel and can produce hazardous airborne emissions. In response, we are developing a plasma gasification system that will enable ...
