Inefficiencies in radar transmitters lead to issues with power generation, heat removal, reduced lifetime, and cost of operation. A high power RF amplifier with high efficiency would be very useful in military and commercial applications. Auriga is proposing to investigate two methods for improving the efficiency of S and X-band amplifiers. Gallium Nitride (GaN) devices will be used to satisfy the ...

Automated assessment and forecasting of aircraft health status has become a prime requirement for safety, reliability, and cost streamlining for 21st century’s aviation sector. Presently, a variety of flight data, functionality, performance, and maintenance information are being collected and some are stored in databases, but an integrated health management (HM) system that utilizes all these in ...

Mayflower Communications Company, Inc. (Mayflower) proposes a Topology Management technology, the Prioritized Unbalanced Traffic Total Yield (PUTTY), to meet the Navy objective, namely, to develop advanced approaches for readily deployable Topology Management algorithms that address the complexity of mobile Ad Hoc Mesh Communication Networks constructed of directional antennas, and demonstrate its ...

Navy pilots have landed for years by capturing a heavy steel cable designed to stop them safely on carrier decks. Multiple cable sets strung across the flight deck are responsible for transferring enormous aircraft deceleration loads to below-deck hydraulic arresting engines. Current steel cables are very heavy, and must be changed after a relatively low number of landings. As the highly lubricate ...

Q-Peak has recently developed “eyesafer” high-power, efficient, thulium (Tm)-doped, 2050-nm-wavelength silica fiber (Tm:fiber) lasers that have the potential to scale up to the power levels needed for shipboard defense. The longer wavelength cannot pass through to the retina and hence presents a greatly reduced eye hazard. Requirements for laser beam quality depend on the nature of the threat ...

Acoustic cloaking – the ability to direct sound completely around an object – is an exciting possibility. Potential military applications include making underwater objects invisible to threat sonar and creating quiet zones where, for example, otherwise noisy manned underwater operations can be safely carried out or where battlefield noise can be contained. Commercial applications are almost li ...

Physical Sciences Inc. will develop a BN/Si3N4 fiber interface coating that can be applied uniformly to fibers in a woven fabric and provide toughening in SiC fiber reinforced ceramic matrix composites (CMCs). Using traditional CVD precursors such as BCl3, NH3, and SiCl4, we will demonstrate a rapid, self-limiting, scalable vapor phase deposition process to create coatings of uniform thickness thr ...

The need for atmospheric pressure, temperature and wind (PTU+wind) vertical profile data over the data sparse open ocean remains a significant problem. Ship-based upper air stations provide synoptic observations but also act as homing beacons for the fleet. Few air-deployed dropsondes are deployed—usually only in hurricanes by specially-equipped WP3 and C-130 aircraft. Future advances in the acc ...

Setting and evaluating spot factor requirements are key steps in the delivery of ship-compatible aircraft to the Navy. However, the current process of generating spot factor results is labor intensive. Templeman Automation LLC (TALLC), in cooperation with Magestic Systems Incorporated (MSI), proposes an automated solution to spot factor and maximum density calculations optimizing the effectivene ...

The proposed shipboard medium voltage AC to DC converter system will allow for various input and output levels based on a power dense, efficient, low cost, high quality output, and modular design expandable up to 6MW. A 450kW power conversion module uses advanced power switching devices and a uniquely designed isolation transformer. The 13.8kV module front-end is connected across a series cascad ...
