The US Navy is seeking improved capabilities to quickly and efficiently generate 3-D target templates (or “site models”) to support such operational systems as the Tomahawk Command and Control Systems (TC2S), Distributed Common Ground Station-Navy (DCGS-N), and collateral damage assessment (e.g., CDET and FastCD). There are two parts of interest. The first is to extract valid and reliable 2-D ...

During Phase I, the Blackhawk hanger bearing and oil cooler fan bearing applications were studied in detail, including analysis of vibration and temperature data from used oil cooler bench tests (conducted by Sikorsky) and used hanger bearing bench tests (conducted by Sentient). This data, along with an analysis of operational and environmental conditions, has allowed us to identify the probable r ...

We propose to develop multiresolution representations and algorithms for synthetic terrain environments. They will be used for representing large terrain models as well dynamic and atmospheric simulations. Our ultimate goal is to increase the validity of the simulation by incorporating the multiple models at varying resolutions. We will use the OneSAF simulation Product Line Architecture Framework ...

Vessels of all types have a limited useful life and must ultimately be dismantled or scuttled as artificial reefs, with wastes properly disposed. The Navy is seeking a means of removing hydrocarbons from inactive ships prior to ship dismantling or sinking as an artificial reef. The Phase I project investigated the use of a biological/mechanical system that was capable of removing free-phase oil w ...

Bearing failure in satellite applications is related to lubricant starvation rather than fatigue, and health monitoring systems for these applications must be able to observe subtle changes related to lubrication state. Phase I included an experimental study to identify candidate monitoring approaches, and the data collected confirmed that cage motion characteristics and instability are highly sen ...

Ultra-high performance multi-function RF electronics are required by the United States Department of Defense to enable next generation radar and sensor networks in response to an increasingly diverse array of threats to our military and our homeland. An elegant potential solution is that of gallium nitride (GaN) RF electronics, which has shown great promise on currently available yet foreign subs ...

Insuring the safety and control of littoral waters is problematic because of the difficulties of surveillance. The preferred methods of surveillance in the ocean are acoustic. In littoral waters, acoustic methods fail because noise from the surf and reflections from the shallow bottom convolute acoustic signatures beyond our capacity to discern them. Water absorbs light, reducing the effectiven ...

Innovative Materials Technologies, Inc. (IMTT) is proposing a Flat Geometry Remote Field & Super Sensitive Eddy Current (FG RFEC & SSEC) technique for the inspection of fastener holes in thick multi-layer structures. Inspection of fastener holes in thick multi-layer structures described in the Topic AF04-134, is a big challenge to all existing or emerging nondestructive inspection (NDI) techniques ...

Three-dimensional woven and braided fiber architectures provide important advantages to composites, including suppression of delamination, high damage tolerance, improved through-the-thickness properties, simplicity and cost-effectiveness of manufacturing complex composite structural components. However, in order to diversify applications and reach high volumes of utilization of these materials in ...

Development of accurate and effective new diagnostic and prognostic capabilities for JSF PHM will require extensive data on both health and faulted systems states. While healthy signatures can be collected quickly and easily, faulted systems are only observed rarely, and duplicating faulted conditions with seeded fault tests is time-consuming and expensive. Simulation models for faulted conditions ...
