Nb3Sn superconducting wire is a preferred superconducting medium for certain applications because of the high field it can produce. Nb3Sn-based wire must be reacted at >600 ºC in an inert environment before use, and the wire¿s insulation also must be heated and remain intact throughout this reaction. Because the reacted wire is too brittle to wind, the wire, with its insulation, is first wound ...

Vibration-Induced Droplet Atomization, or VIDA, is a thin-film spray cooling technology developed at Georgia Tech with tremendous potential for thermal management applications in future Navy ship power electronic systems. The patented VIDA technique uses avibrating piezo driver in a self-contained cell to deliver a highly controllable, rapid-response, on-demand aerosol-sized water spray to hot ele ...

A goal of the Future Combat System (FCS) is to perform resupply functions under combat conditions without exposing friendly personnel. With the demonstrated success of autonomous vehicles in the Army Research Laboratory's DEMO III Semi-Autonomous Off RoadMobility program this goal is now achievable. Autonomous vehicles become

The mitigation of mainlobe jamming is essential to missile defense radar performance. Applied Radar is currently investigating distributed aperture and adaptive processing architectures that promise a new generation of advanced radar performance. Our proposed program will research the application of these distributed aperture radar techniques to determine the mainlobe jammer suppression possible w ...

Ballistic missiles pose formidable challenges for target tracking and intercept because of their spiraling dynamics and significant maneuverability potential as they re-enter the atmosphere at high speeds. Recent studies have shown that conventional methods to estimation, guidance and control design are unable to guarantee sufficient accuracy against such highly maneuvering targets. This is not un ...

The nature of electromagnetic launchers requires operation in a harsh environment due to the large electromagnetic field, electrical current, temperature, and mechanical stresses present during a shot. This environment can significantly reduce the lifetime of the rails and therefore limits the military utility of the device. Increasing the lifetime of the rails while maintaining high launch velo ...

The design and development of phased-array radars requires the integration of solid-state components and adequate thermal mitigation within the array lattice constraints. The current trend is towards increasingly planar designs and a reduction in the array depth. The MDA SPEAR program is one example in which a planar T/R “tile” architecture is utilized. System-on-a-chip technologies such as Si ...

Fluorescent and incandescent lighting consumes more than 50% of the lighting energy budget. However, these technologies are relatively inefficient, losing approximately 37% and 85%, respectively, of their energy to IR, rather than visible, frequencies. Efficient IR-to-visible upconversion phosphors could have a significant impact on lamp efficiency and design. This project will develop Concentrica ...

Recent advances in mammalian artificial chromosome design and engineering offer an alternative to existing methodologies for cellular bioengineering and address unmet needs to bioengineer more complex functionalities into human cells for subsequent commer

The NASA code OVERFLOW is used extensively by academia, government institutions, and industry for a wide range of applications. Successful completion of Phase 1 and 2 efforts will enhance the solver and provide more accurate computations. These computations can be used to better understand the underlying physics of stalled and unsteady flow. Specifically, the advanced model can be used to test ...
