Shipboard structures employing composites typically use glass/vinyl ester (VE) manufactured with vacuum assisted RTM. This composite system offers reduced weight, no corrosion and improved signature performance but lacks the fire performance characteristics required for shipboard use. Phenolic resins (PH) provide outstanding fire performance but are difficult to process and offer lower structur ...

Ultrafiltration membranes offer great potential for compact, low cost clean-up of Navy surface ship graywater and blackwater. A major limitation of these ultrafiltration membranes is significant loss in flux with time associated with membrane fouling from proteins, polysaccharides, and other waste products. Backflushing can only be used to a limited extent. Chemical treatments are undesirous si ...

Accurate performance prediction is crucial to the simulation, analysis and flight testing support of rotorcraft. In this regard, current analysis tools inadequately model key phenomena like blade dynamic stall, rotor tip loads, and rotor downwash because of their failure to predict the true unsteady three-dimensional nature of the aerodynamic environment near the rotor. Continuum Dynamics, Inc. ...

The project examines the concept of frequency selective antenna management and supplemental transmit antennas on tactical aircraft which allow continuous jamming and support maneuvering. The project examines tactics and coordinated techniques responding to crew actions and cueing techniques to prompt optimized maneuver synchronization. Phase 1 identifies the threats, the techniques, and estimate ...

Recent advent, and significant progress made in the wide-band-gap semiconductor technology offer today a promise for a superior high power phase shifter. More specifically, emerging Gallium Nitrate (GaN) HEMT devices are shown to operate in extreme temperatures (~600C), exhibiting high breakdown voltages (~100V) and high current densities (~1.5A/mm). In order to meet these challenging technical re ...

The objective of this proposal is to demonstrate the feasibility of an innovative design that utilizes ozone to break the oil-in-water emulsion stability in bilge water by oxidation. Ozone, a very strong oxidant, is capable of reacting with many substances by either directly or indirectly attacking the bonding substrates. This process can convert surfactant coated oil into a non-polar sensitive ...

There are immediate needs for fast and cost-effective detection of concealed information or intent in homeline security applications such as border control, critical facility access. Unfortunately, traditional polygraph is not suited for this type of fast screening applications because it requires invasive contacts and extra time to administer. To meet today demand, new modalities have to be studi ...

The US Navy continues to research and develop advanced automation technologies to reduce the manning required to operate the next generation of combatants, without compromising platform survivability. One of the most manpower-intensive activities is damage control, during which time critical systems are shut down or re-routed to keep the ship operational. Sailors have typically been the only mea ...

To mitigate the parasitic characteristics of radio channel, an intelligent RF control plane is desired. Spectrum Management for shipboard wireless modems, consideration for on shore equipment support, emphasis on exiting Wireless LAN protocols (802.11) with consideration for ultra wideband and even IR WLANs, are all required for maximizing radio functionality without having to maximize radio exper ...

The inexpensive RPG has caused havoc with US armored vehicles since WWII. Therefore, MSI has conceived of an active protection system that consists of six evenly spaced stationary horizontal gun tubes, able to shoot projectiles containing thousands of tungsten balls toward an RPG firing, as detected by infrared sensors between gun tubes. The frangible ogive that contains the balls is designed to ...
