"The goal of this project is to characterize the magnitude and transmission paths of bone-conducted noise, and then to use this information to design an effective Noise Reduction System (NRS) for use in crew helmets. US Navy personnel working on the decksof aircraft carriers operate in a very high noise environment and are at considerable risk for hearing damage. There is no technology available ...

"Barrel erosion, which is produced by the combination of hightemperature and pressure with aggressive propellant combustionproducts, and the action of the projectile, results in decreasedmuzzle velocities, increased projectile yaw, and decreasedaccuracy. New material designs are needed to mitigate erosion ingun barrels, which limits service lifeCeramic composites are a leading material candidate ...

The Advanced Lighting System Affordable Technology (ALSAT) effort proposes to develop a low cost, high power, full color spectrum and full dimming level standardized LED light engine/fixture that is form, fit, function compatible with existing shipboard lighting configurations. The light engine/fixture will employ active real time spectral control that will provide repeateable and standardized out ...

"The goal of the proposed Phase I effort is a feasibility study on the design and development of an innovative, fail-safe, controllable magneto-rheological fluid (MRF) smart pad for shock and vibration mitigation of Trident submarine based vertical launchweapon systems. The objective of this project is to explore the design feasibility of the proposed MRF shock absorber system which consists of a ...

Human biometric recognition systems are essential in the automated personal identification and verification applications market. This market spans the commercial and military sectors to include a myriad of identification applications from secure entrance, to time card clocks, to bio-certified delivery systems, to automobiles that recognize their drivers, to money transaction systems, to weapons th ...

"Turbine blade tip failure is one of the most critical issues facing future development of gas turbine engines. This proposal describes an inexpensive method to deposit a highly effective micro heat exchanger made from a MCrAlY alloy on the tip of ablade. The combination of the very efffectively cooled tip and the excellent mechanical and oxidation resistant properties of MCrAlY alloys will a ...

A precision air-drop capability is required to allow the re-supply of Special Operations Forces (SOF) behind enemy lines. The covert nature of these operations makes it important that the drop occur with low visibility. Furthermore, a wide range of dropparameters will give the drop-aircraft the freedom to avoid detection. Creare proposes a novel AutoRotating Air Delivery System (ARADS) that wil ...

"Special forces personnel are often subjected to physically abusive conditions during transit to and from operation sites. At best, these conditions result in accelerated fatigue and reduced mission performance, and at worst, in injuries such as musclestrain or stress fractures. It is our hypothesis that by maintaining optimal body postures during transit, the net shock levels on muscles and bon ...

The objective is to modify and test gas turbine engines presently installed in/on marine craft to demonstrate that by adapting technology used on street legal vehicles can be used to reduce the heat and noise levels in marine craft. Whether or not the IR15dB level or lower, and the above water acoustic/noise level to 60dB level or lower can be achieved, is a matter that can only be demostrated by ...

As the U.S. Navy moves toward greater shipboard electrical loads, advances in transmission, distribution, and protection technologies are becoming more important. In particular, as fault currents increase due to the use of generators with greater voltage and fault currents, circuit breakers with insufficient breaking or short duration carrying capacity are put at risk. Finally, as the U.S. Navy ...
