ABSTRACT: Providing electrical power for long duration hypersonic flight is a technology that is required to bring about this revolutionary mode of transport. Whether for weapons delivery or for space access, the long duration missions anticipated require a novel approach to the generation of electrical power during flight. Scramjets contain no rotating shafts from which typical generators or mec ...

Future multiband communications systems demand frequency agile filters. While such devices are available at millimeter wave, they suffer from large size and high cost, among others. For this STTR Phase II effort, nGimat, working with Georgia Tech, will develop a miniaturized, low-loss, tunable Ka-band bandpass filter using its low-cost tunable thin film technology. In Phase I, nGimat has succes ...

The region of the millimeter and submillimeter-wave frequency bands, from 100 GHz to 3 THz (wavelengths of 3 to 0.1 mm, respectively), are some of the least explored and yet information rich regions of the electromagnetic spectrum. This region of the spectrum, referred to as the terahertz (THz) frequency regime, roughly 300-3000 GHz, is ripe for development. A major impediment to development of a ...

Cermet, Inc in collaboration with Georgia Institute of Technology proposes to develop spin Light Emitting Diode (LED) in a 24 month Phase II program. The spin LED is a simple yet powerful spintronic device that produces circularly polarized light and is a potent tool to quantify the spin injection efficiency and spin polarization efficiency.

nGimat Co., in collaboration with the Georgia Institute of Technology, and the Wright-Patterson AFB Air Force Research Laboratory, proposes to develop a fuel injection method and advanced numerical simulation tools for injection of fuel at supercritical conditions in aero-propulsion combustors. This project is designed to accelerate understanding and commercialization of transcritical and supercr ...

Combustion powered actuation (COMPACT) is a flow control technology developed at Georgia Tech which utilizes a miniature combustion chamber (cubic centimeter scale) to produce high-speed pulsed jets suitable for aerodynamic flow control (separation control, drag reduction, shock control, etc.) at transonic or supersonic speeds. The system is lightweight, can be operated with passive fluidic valve ...
