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 ...

Face-to-face communication between crew members launching and recovering aircraft on a carrier deck is impaired by the high-noise environment. High-noise levels also mask the various audio cues that provide situational awareness. Effective communication and good situational awareness are keys to safe and efficient operations. Creare proposes a Talk Through Noise (TTN) system that will improve f ...

High-temperature (HT) polymer matrix composites (PMCs) are desired for many aerospace and military applications. Silicon carbide (SiC) fibers provide a potentially attractive reinforcement for HT PMCs for applications ranging from propulsion systems to structures for the orbiting space plane. The sizings routinely added to commercial SiC fibers are not compatible with the new HT matrix resins. ...

Superconducting degaussing, propulsion and power systems offer potential weight, size and performance advantages over conventional systems. High temperature superconductors enable superconducting operation at higher temperatures, reducing the size and complexity of the cooling system. Many of the required technologies for these systems are commercially available. However, new connector technology ...

Powder production is often the rate limiting step in thermal battery production. The current powder production technique for lithium-based alloys and electrolyte is costly, labor intensive, time consuming, and leads to highly variable product. Because of the extremely reactive nature of these materials, advances in this area are difficult because of the special care that must be taken in the sele ...

An aqueous-based finish (sizing) was developed in Phase I to improve the carbon/vinyl ester interfacial bond. The finish is composed of a reactive coupling agent, a low viscosity vinyl ester resin, a free radical inhibitor, and a surfactant. The reactive finishes substantially improved the carbon/vinyl ester interface compared to unsized or FOE sized materials. Failure mode analysis shows that ...

Desire to operate gas-turbine engines at higher gas temperatures, beyond melting points of metal airfoil components, for improved engine efficiency and performance, drives demand for more durable, less conductive ceramic thermal barrier coatings (TBCs) that insulate metals from hot gas streams. Particularly for aircraft, TBCs must withstand the most demanding temperature gradient and stress from ...

Advanced propulsion systems for the Joint Strike Fighter (JSF) aircraft require the use of advanced materials for longer life, reduced weight, and increased performance. Ceramic matrix composite (CMC) materials have the potential to realize these benefits; however, the high cost of finished CMC components make wide implementation impractical. To reduce these costs, new, innovative fabrication te ...

The smaller warcraft envisioned by The Electric Warships and Combat Vehicles Future Naval Capability need to reduce the size and weight of all shipboard systems. Wireless sensors offer enormous potential for meeting these needs by eliminating heavy, costly and failure-prone wiring. Government wireless systems must include an effective security system to prevent attacks on sensitive data and the ...

The Navy intends to start using a significant quantity of composite structures in surface ship construction in an effort to decrease costs as well as to reduce the visibility of the ships to radar. The large size of the target structures necessitates the use of low temperature, non-autoclave processing techniques such as Vacuum Assisted Resin Transfer Molding (VARTM). In the recent past, most m ...
