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 ...

EOSPACE proposes to develop a Compact Array of Analog Modulators and Integrated Laser Source (CAAMILS) module for use in a wide-bandwidth analog ladar scene projection system. Under Phase I, EOSPACE used its unique, exceptionally low loss, lithium niobate (LiNbO3) integrated electro-optic waveguide technology to fabricate a practical and cost-effective, yet state-of-the-art, ultra-low-loss, high- ...

Advancements in military communications technology will enable better information gathering and decision making, but they require reliable, robust, quiet, and highly portable electrical power. The Free-Piston Stirling Engine generator system that is the subject of this proposal has excellent potential to meet these needs better than any identified alternatives. Stirling Technology Company’s (STC ...

The purpose of this project is to develop a complete geographic text processing system for tagging place names in text files and visualizing the results in a map display. While tools exist for automatically identifying place names in text, this effort focuses on significantly improving the current capabilities within the context of an end-to-end system. In Phase I, we developed a functional protot ...

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 ...

Lithium oxyhalide batteries offer energy densities several times higher than thermal batteries. Like thermal batteries, lithium oxyhalide batteries have unactivated storage lives in excess of 20 years and are mechanically rugged. Some of the main advantages that lithium oxyhalide batteries offer are flat discharge voltage profiles and potentially long operating lives. However, battery performanc ...

The projected cost for the Mentis Sciences, Inc., (MSI) prototype PAC3 radome is 1/6th of the total cost of the present system. A Pareto analysis of the current MSI process indicates that the two largest costs in radome production are the direct labor associated with fabrication and the cost of the raw materials. In Phase I MSI demonstrated that COTS paint spraying technology reduced the direct ...

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 ...

Advanced space-borne infrared detectors require cooling at temperatures near 10 K. Cooling loads for these detectors will range from 0.25 W to 1.0 W at 10 K, with additional loads at higher temperatures. A multistage cooler, capable of cooling multiple loads, will offer large potential gains in system efficiency and weight. Turbomachine-based Brayton cryocoolers are ideal candidates for these m ...

DNA microarray technology, in combination with statistical and predictive modeling tools, could be used to evaluate thousands of genes against distinct gene expression patterns induced by chemical/biological agents to provide early identification and speed therapeutic intervention. The overall objective of this Phase II effort is to leverage existing public domain resources and commercial tools t ...
