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 ...

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 ...

At a recent DIA briefing to industry, intelligence community representatives reiterated the urgent need for improving the TPED process to meet the operational need to obtain persistent intelligence about on the battlefield. TPED is the process of sensor tasking, sensor processing, sensor exploitation and report dissemination. The requirement to improve the ISR TPED process has been articulated ...

While recent efforts in cross-domain information sharing have developed platforms and infrastructure for information sharing, they do not address the question of the content of the information that is being shared. This project will develop the latter capability: identifying information that is (i) relevant and (ii) sharable. This is a key problem in "just enough" data sharing, especially in crisi ...

The innovative use of variational methods to dynamically segment scenes, which leads to a fast, natural approach to estimating the location of unknown 3-D obstacles is proposed. The previously developed algorithm has been shown in simulation to be suitable for real-time processing in flight using current generation processors, and to be robust in the presence of transient sensor data, distortion, ...

Currently aircraft composite and metal structures are joined by fastening them in place using riveted or bolted joints. Although fastened joints largely avoid concerns associated with thermally induced stresses and strains from CTE mismatches, such designs add weight, manufacturing complexity and cost to the design. Recent advances have given rise to opportunities to increase the integrity and p ...

With growing demand for reduced emissions during peacetime, the Air Force requires fuel cell technology for its various power needs including portable field devices and tent cities deployed overseas. To meet these needs with a reforming process, feed fuels will vary: when in the United States, natural gas is readily available while in other countries, JP-8 fuel will be used. In this Phase II pro ...

The formation of exchange coupled permanent magnets consisting of nanometer sized hard magnetic grains enveloped in a soft magnetic matrix has been demonstrated experimentally to increase the energy product of advanced magnetic materials. Additional gains are still predicted, but improved control of the nanostructure must be achieved through a route that is both performance and cost effective. n ...
