AN/PSC-2 DIGITAL COMMUNICATION TERMINAL (DCT) REQUIRES A POWER CONVERTER THAT CONVERTS 115 VAC TO 8 VDC FOR ABOARD SHIP USAGE. THE HIGH TEMPERATURE AND HUMIDITY CONDITION ON THE SHIP, COMBINING WITH THE POSSIBLE SALTY ATMOSPHERE CAN GREATLY LOWER THE RELIABILITY OF ANY ELECTRONIC DEVICE BECAUSE OF THEIR CORROSIVE ACTION ON THEM. THE PROPOSED CONVERTER IS BELIEVED TO SURVIVE THE HARSH ATMOSPHERE CO ...

THE OBJECTIVE OF THIS RESEARCH IS TO INVESTIGATE NEW FAULT TOLERANT ALGORITHMS AND MODELING ENVIRONMENTS FOR USE IN RELIABILITY DESIGN AND EVALUATION OF MODEL MULTIPROCESSOR NETWORKS SUCH AS FLIGHT CONTROL SYSTEMS AND HIGH-RELIABILITY COMPUTER SYSTEMS FOR NUCLEAR PLANT SAFETY SYSTEMS AND OTHER MISSION-CRITICAL WEAPON PLATFORM COMPUTERS. EMPHASIS IS PLACED ON FAULT TOLERANCE RELATED TECHNIQUES WHIC ...

PROPOSED IS AN OPTICAL CORRELATOR OR CONVOLVER CAPABLE OF ACCEPTING RASTER SCANNED IMAGERY AT VIDEO RATES, AND CORRELATING WITH A LARGE LIBRARY OF REFERENCE IMAGES.

For the U.S. Navy, Creare is developing a Compact Swaging Machine (CSM) to attach arresting gear Purchase Cable terminals on ship. Our CSM utilizes three innovative features to dramatically reduce the size and weight of the swaging machine to make it usable in a shipboard environment: (1) a high pressure hydraulic system which minimizes the actuator size, (2) an efficient swaging schedule which re ...

Wave Computation Technologies and Duke University will develop minimally coupled, co-mingled E and B field antennas through numerical and experimental investigations based on first-principle theories. The project objectives are to (a) develop the simulation capability for modeling superconducting quantum interference filter devices and the related B field antennas, (b) make appropriate designs of ...

The Tai-Yang Research Company in partnership with the Center for Advanced Power Systems at Florida State University proposes to develop a warm-to-cold electrical termination for a cryogenically cooled high temperature superconductor cable. The termination will be optimized for the requirements defined by the Next Generation Integrated Power System. The proposed termination will include a novel met ...

Future military communication systems will rely on advanced superconductor digital electronics. These electronics will require efficient cooling at low temperatures near 4 K. Pulse-tube cryocoolers are a candidate cooling technology for this application. We propose to improve the efficiency of the pulse-tube cryocooler by addressing one of its primary performance limitations, namely the performanc ...

The performance of modern combustion systems used in propulsion devices (such as gas turbine main combustors, augmentors, and rockets) is largely dependent on the mixing of fuel and oxidizer. This mixing process, often involving a liquid jet emanating into a gaseous flow followed by subsequent breakup and atomization, is critically important to many performance metrics including thrust, efficiency ...

In miniature gas turbines for UAV applications, traditional bearings exhibit a typical lifetime of only 25 hours due to excessive axial loading. Mainstream proposed a passive permanent magnet thrust bearing to alleviate this problem and increase service life to over 1000 hours. Since this type of bearing is non-contacting, it can operate at very high rotational speeds with minimal heat generation ...

Unnecessarily high battlespace fuel consumption degrades operational capability, increases force balance problems, exposes refueling convoys to high risk, and increases operating and support costs. Currently, military shelters are cooled by vapor compression air conditioners powered by diesel electric generators. Diesel generators, which are overwhelmingly used for shelter cooling at forward bases ...
