Development of a compliant microfabricated heat exchanger to work with thermoelectric devices as a means of power generation for hypersonic vehicles is proposed. Polymer-based materials provide to provide compression on the thermoelectric module, to ensure optimal thermal contact, while allowing for… More

High current electron sources are required in numerous applications of interest to the DOE; however, current RF guns based upon thermionic cathodes and photocathodes have serious limitations. While thermionic cathodes have high average electron currents, they suffer from degraded beam quality when… More

ABSTRACT: The potential of scramjet engines for use by the U.S. military would revolutionize countermeasures enabling rapid responses to global hot spots. The scramjet traveling at hypersonic speed cannot use rotary power typically employed at sub-Mach velocities, while auxiliary power units and… More
