Accurate Automation will design a weakly ionized gas drag reduction system for an advanced fixed wing aircraft. To this end we will develop a theoretical model for the WIG drag reduction phenomena, initiate a series of two dimensional shock tank experiments, evaluate the engineering feasibility of employing the technology on an operational aircraft, and perform a conceptual design for a wind tunn ...

Under this project and with a follow-on Phase II, Accurate Automation will build a hand-held device for Forward Air Supprt--Marine (FASM). This device, the Hand-held Terminal Targeting/Control System (HTTS) will enabe a Marine forward observer to perform terminal control of a ship-launched missile (e.g., ERGM). It will also support two-way development of SA; the forward observer will be able to ...

High power lasers are needed for many airborne applications. These lasers must be compact, reliable in high vibration environments, and must also have a low per unit cost. Aculight proposes to develop a high repetition rate laser with average power of 10-20 watts using novel packaging designs and manufacturing methods. When fully developed, this technology will provide flight-worthy lasers at a ...

Improving the optical beam brightness of diode laser bars and optically pumped semiconductors is essential for many Air Force and commercial applications. In this proposed work Aculight will build and test a MIT/LL optical approach for decreasing the angular divergence of diode laser bars by a factor of at least 80. The MIT/LL approach will be implemented using Aculight's newly developed optical ...

AN EFFICIENT COMPUTATIONAL METHOD IS PROPOSED FOR MODELING THE COMPLEX PHYSICAL PHENOMENA OCCURING IN HIGH ENERGY CONTINUOUS WAVE LASER FLOW FIELDS. THESE FLOWS TYPICALLY CONTAIN BOUNDARY LAYERS, MIXING LAYERS, WAKES, AND EMBEDDED SHOCK WAVES. IT IS DIFFICULT TO GENERATE A MESH APRIOR WHICH WILL RESOLVE ALL FEATURES OF THE FLOW. THEREFORE, AN ADAPTIVE GRID TECHNIQUE WILL BE USED AND COUPLED TO AN ...

REQUIREMENTS FOR MATERIAL CHARACTERIZATION ARE BECOMING MORE STRINGENT AS THE ROLE OF THE TRACE ELEMENT COMPOSITION OF HIGHTECHNOLOGY DEVICES BECOMES APPARENT. IN SEMICONDUCTOR RESEARCH, FOR INSTANCE, THERE IS A NEED FOR ULTRA-TRACE ELEMENT ANALYSIS IN SOLIDS BELOW THE PPBA LEVEL WITH SPATICAL RESOLUTION IN THE FEW MICRON RANGE. RESONANCE IONIZATION SPECTROSCOPY (RIS) INVOLVES THE STEPWISE EXCITAT ...

A direct write machine capable of writing metals, dielectrics, ferrites and resistive materials, would be an effective tool for rapid prototyping and design for electronic circuits. A versatile machine of this nature could also be implemented with the capability to deposit the necessary materials to directly write a solar cell. This added benefit to the feasibility of using specialized devices t ...
