The Acoustech Corporation as the prime contractor and the Pennsylvania State University - Applied Research Labc-atory as the subcontractor propose to design, manufacture, and test an underwater acoustic intensity probe containing a geophone and two-hydrophones encased in a neutrally buoyant package. The results of this proposed effort are anticipated to be highly successful since the researc ...

While circuit simulation tools have revolutionized the art of RF and microwave design, these tools are only as good as the component values they employ. The increased demand for reduced design cycles and easier to manufacture systems has generated the need for accurate and reliable tools. Current circuit simulation tools use component models that do not always account for parasitic coupling, non ...

This SBIR program will address the modelling, fabrication, and testing of single crystal composite transducers. Comprised of single crystal relaxor-PT piezoelectrics, both single element and array configurations will be investigated for high performance medical ultrasonic imaging transducers. In collaboration with TRS Ceramics, Inc., single crystal relaxor PT piezoelectrics will be integrated in ...

As a consequence of the under-developed current state of Congnitive Systems Engineering (CSE), the resulting decision support systems (DSSs) are therefore weakened/lessened in terms of effective support to the users. A radical advance in the practicality and efficiency of CSE as an integral component of an overall system development process is an essential breakthrough. This proposal outlines a ...

For this Phase I SBIR program, high volumetric efficiency, energy storage capacitors are proposed using phase change ceramics. These materials are nonlinear dielectrics that make use of electric field induced antiferroelectric to ferroelectric phase transition to store more energy per volume than is possible with linear dielectrics (10 J/cm3 compared to 2 J/cm3). Furthermore phase change materia ...

The focus of this research is on designing an instructional environment for aiding the acquisition of concepts involving dynamic spatial reasoning needed for air combat maneuvering (ACM). The key ACM concepts involve movement in time and space, which are difficult to communicate in lectures, print media or conventional CAI incorporating text and static graphics. CHI Systems proposes to combine i ...

The systematic upgrade of a two-phase (gas/particle) missile propulsive Navier-Stokes code, CRAFT, to simulate the three-phase combustive processes occurring in rocket combustion chambers and nozzles is proposed. Preliminary emphasis is on upgrades that will improve the ability to analyze combustion processes in the secondary combustion chamber of ducted rocket engines (DRE). This will involve i ...

A state-of-the art CFD methodology that has well established aero-acoustic capabilities will be implemented for -investigating turbulence/acoustic interactions that characterize cavity flowfields. Exploratory numerical investigations will be conducted using the three-dimensional, finite volume CFD code, CRAFT , which utilizes a fully implicit, characteristic based upwind scheme with higher o ...

The goal of this SBIR project is to increase the effectiveness of Precision Guided Missiles (PGMs) by integrating weather forecasts, aircraft-sensed weather conditions, and weather data from remote sources into the mission planning process. The benefits will be more precise targeting, better "Go/No Go" decisions, and more effective use of precision stand-off weapons. In Phase I, we will: det ...

This proposal is concerned with a large area, high speed photodetector with gain. It involves the incorporation of a metal-semiconductor-metal (MSM) diode as the anode in a large area phototube that currently uses a Schottky diode. Present photodetectors either have a large area and low speed or a small area and high speed. The proposed phototube, or the intensified photodiode (IPD) is expecte ...
