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 ...

A fully reconfigurable multi-carrier rf communications system requires a fast, versatile switch matrix, which will permit distribution of various signals between a set of antennas and a set of radios. This is carried out most efficiently in the digital domain, but requires the use of ultrafast circuits that can accurately process multi-GHz rf signals. Superconductor electronics can provide high- ...

An innovative program to develop high efficiency (>40%) MMIC power amplifiers at both Ka-Band and Q-Band for Phased Array applications.The power output for the Ka-Band is 2watts while the power output for the Q-Band amplifier is 1.5watts. A primary objective of the program is to produce these amplifiers at a very low cost in production that will make phased array systems more affordable. A key com ...

Scientific advances have made it possible to understand phenomena on the atomic, molecular, microscopic, and macroscopic scales. That increased understanding has led to the development of a variety of software packages that provide simulation capabilities on each of those scales. However, many new challenges in product developments require simulations at different scales and require functionality ...

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 ...

Based on the problem formulation for pursuit-evasion differential game with the payoff of the optimal capture time and innovative multi-pursuers multi-evaders differential game techniques developed in Phase I, Impact Technologies, in collaboration with the Georgia Institute of technology, propose to develop the design tool prototype for stochastic pursuit-evasion differential games with multi-pur ...

The Army has a strong need for very high-energy density (> 1000 WH/kg), light weight power sources for communications and other advanced electronic devices. The possible solution is replacing the battery with hydrogen based proton exchange membrane (PEM) fuel cell. However, hydrogen storage and handling is a problem. Direct oxidation fuel cell (DOFC) with a PEM is quite attractive alternative. How ...

The objective of this project is to commercialize the Dual Band Extended Depth of Field Telescope System that is an innovative optical detection and imaging system that allows battlefield imaging through smoke, dust and fog obscurants in the 10 micron wavelength range. The system employs a dual band, multi-mode, diffraction-limited, infrared and visible telescope that can operate either in a passi ...

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 ...
