The computational grid generation process remains a troublesome bottleneck in development of aerodynamic databases for complex geometries and multi-body configurations. The ability of Cartesian-grid based methods to perform automatic mesh generation and dynamic mesh adaptation allows for substantially reduced manpower, time and cost. The advantages of octree-based Cartesian-mesh methods have been ...

The size of conventional split ring transducers is much smaller than a wavelength at operating frequency leading to a high Q resonance and limited operating bandwidth. The proposed work will investigate two different modifications to the split ring structure that allow its resonance frequency to be adjusted under active control so that it is always operated at or near its resonance. Because the ...

Etrema Products, Inc. and Applied Research Laboratory at The Pennsylvania State University demonstrated during Phase I that by utilizing the “delta-E” effect in magnetostrictive materials, the resonant frequency of a split ring transducer can be shifted by over 200 Hz for a low frequency transducer. A variable reluctance driver helps achieve source levels in excess of 210 dB with a potential ...

The purpose of this project is to determine if an Ultra-Wideband radar array sensor can be used as an effective perimeter security sensor to detect, track and classify targets. If this can be determined, then the next step will be to produce a proof of concept unit, then demonstrate and characterize the performance in a multitude of real life scenarios. If successful, this effort will result in ...

Phase I concluded that an Ultra-Wideband (UWB) radar array sensor, could be employed as an effective perimeter security device to detect, localize, track, and classify targets. It also concluded that as an enabling perimeter security technology UWB offers significant advantages over conventional IR and Microwave systems. A Phase II plan has been proposed. In this plan, a prototype perimeter sec ...

LIT will improve FPGA sanitization techniques, develop Tamper Detection (TD) technology, and begin developing an Anti-Tamper Integrated Circuit (AT IC). LIT will pursue National Security Agency (NSA) qualification of the developed products and technology as appropriate. In Phase I LIT developed techniques for sanitizing FPGAs and associated configuration memory. In Phase II LIT will develop impr ...

The Significant Optical Manufacturing Advancement (SOMA) program will capture the principles of Design for Assembly (DFA) and apply them to the fabrication of precision optical systems. This will provide the Navy with the ability to design optical systems that can be assembled efficiently for much lower costs. We will use the DFA discipline of axiomatic design coupled with optical design equations ...

The overall objective of this project is to develop a system-level prognostic modeling tool for predictions of the spread of chemical/biological agents in shipboard air systems. The intent is to integrate the tool with existing DC systems. The proposed system will be modeled as a set of interacting software components coupled through a simulation environment. To achieve execution speed and accurac ...

CFDRC has completed preliminary design of a next generation Ram Air Turbine (RAT) suitable for operation in the Navy’s next generation electronic warfare pod. The RAT will be capable of delivering 60 KVA at a sea level flight speed of 280 knots. The unit will also be capable of providing adequate liquid coolant to maintain electronic component operating temperatures below specified levels. Du ...

Photon-X is pleased to propose the next generation of corrosion detection devices to assist the Navy achieve its goal of reducing the impact of corrosion of aircraft maintenance cost. Our technology is an innovative integration of Spatial Phase Imaging (SPI) applied to both high-resolution video imaging and Terahertz (THz) imaging that captures full 3D volumetric analytical information of both sur ...
