Optical measurements including laser velocimetry (LV), particle image velocimetry (PIV), and other similar techniques are becoming a more important part of aerodynamic testing. However their implementation into large production wind tunnels is severely hindered by difficulties with flow seeding. Phase I of this program will focus on the problem of seed delivery and dispersal into a transonic strea ...

Prior to this project, zero net mass flux Synthetic Jet Actuators (SJAs) were used primarily as a mechanism to keep flow attached that would otherwise be separated. Thus, SJAs located near a wing’s leading edge have been shown in experimental projects such as the NASA/GTRI Stingray UAV to be effective for producing forces and moments suitable for flight control only at high angles of attack. I ...

Aerotonomy, Incorporated, and our research institution partner Georgia Tech Research Institute (GTRI) will continue development of our unique two-stage Multi-Disciplinary Optimization (MDO) system for the design of highly integrated miniature broadband antennae for small UAVs. The concept of structurally-integrated multifunction antennae embedded into airframes is central to the DoD’s "smart sk ...

The Air Force Research Laboratory (AFRL), U.S. Air Force and agencies like the National Aeronautics and Space Administration (NASA) have a current and future need for advanced commercially available inherently rad-hard primitive cell libraries to support new designs for satellites and other spacecraft. American Semiconductor Inc. proposes a new core cell library that can meet next generation high ...

The use of carnauba wax in melt/castable explosives yields a insensitive explosive formulation that enhances overall safety for the use of these munitions in the field. However, carnauba wax is only obtained from overseas sources and there is no domestic source for this material. This leads to shortages of material and higher prices. There exists a need for a wax substitute to replace the carna ...

Brushfire Technologies proposes to adapt our secure local area network gateway to the unique requirements of the DMO network to detect, analyze and mitigate security threats in real time with no adverse affects on network performance. Security analysis based on real time packet inspection coupled with application awareness and heuristically derived network topology information provides unpreceden ...

Accurate numerical predictions of antenna performance on aircraft are important in many problems of avionics design and integration. In particular, such predictions are needed to determine optimal antenna placement on aircraft in order to achieve required coverage. The focus of this project is an investigation and development of new high-frequency computational methods and codes for accurate and e ...

Cermet, Inc in collaboration with Georgia Institute of Technology proposes to develop ZnO based light emitter with light emission wavelengths ranging from UV to IT. On successful completion of the proposed effort, the market place will have a unified device structure based ZnO that emits light from UV to IR. The proposed work will be accomplished by the researchers from Cermet and Georgia Institut ...

A methodology is proposed to provide intelligence to more classical global optimization schemes. By incorporating these methods, design engineers will be able to not only identify and resolve difficulties within an antenna element, but will be able to synthesis and optimize an entire array, including the antenna elements, feed structures, array position and shape, element location and orientation ...

Since the 1990's, applications requiring high power (>1 KW) millimeter wave energy have relied on either gyrotrons or multiple gryotwystron amplifiers. While the gryotwystron approach offers bandwidth and single point failure benefits, it is inherently more complex and larger than that of the single gyrotron. The gyrotron however requires a superconducting magnet to create the 3.7 Tesla field ne ...
