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 ...

AgilOptics’ Phase I SBIR proposed the development of a moire¢ Wave-Front Sensor (MWFS) test-bed to evaluate the MWFS design developed and patented by the University of New Mexico (UNM) and to extend the design for use in a closed-loop Adaptive Optic (AO) system with a Micro-Electro-Mechanical System (MEMS) Deformable Mirror (DM) corrector. Our Phase I results have shown that the MWFS provides i ...

The proposed effort is to develop a frequency and waveshape agile pulse forming system. The pulse forming system is based on a Blumlein topology and allows a wide range of waveforms to be generated from a fixed set of mechanical hardware.

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 ...

For a variety of warhead concepts, both for air-to-air applications and ground-based, it is desirable to explore new material combinations that provide enhanced lethality and functionality. For example, it may be desirable to combine materials that have high density with those having pyrophoric or other properties. In such advanced air-based weapons systems such as PIOS (Programmable Integrated ...

This effort creates foundations for highly automated simulation tools that predict warpage in printed circuit boards and assemblies (PCAs/PCBs) and chip packages. Our technique, MHS, provides core capabilities to automate warpage and other problems that were impractical until now. MHS extends a multi-representation approach the PI first conceived at Georgia Tech for CAD-CAE interoperability. This ...

Aberrations due to aero optics effects around a turret in flight cause degradation of any optical beam traversing the turret. The degradation causes reduction in system performance of directed energy weapons in terms of the lethality range and increased dwell time as the energy on target is reduced. Kestrel Corporation has developed a new wavefront sensors based on measuring the curvature of the ...

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 ...

Situation awareness involves the real-time understanding of emerging events, impacts, threats, and effective responses. Situation awareness requires the mutual interplay of perception, comprehension, and anticipation to dynamically refocus attention, adapting sensor and cognitive resources to accurately track unfolding events. The objective of this research is to continue development of a computat ...
