Reduction in Shock / Vibration Levels Experienced During Dynamic Warhead Testing

Not Available Advanced Thermal and Environmental Concepts (ATEC) Inc. in collaboration with Refractory Composites Inc. (RCI) propose to develop an EHD- enhanced carbon-fiber heat exchanger that can demonstrate heat transfer enhancements substantially beyond the range of conventional technology for air/liquid compact heat exchangers of significance to the AAAV program. Phase I effort will quantify the potential for substantial size/weight savings and/or performance improvement, relative to the state-of-the art technology, for EHD-enhanced air/liquid heat exchangers of interest to the AAAV program. Evaluation will capitalize on the proposers team's extensive technical know-how and experience with EHD-enhanced heat transfer and carbon-fiber composites and will employ a combination of computations and experiments to identify the best candidate(s) application for the AAAV program. Technical obstacles associated with using an EHD-enhanced carbon-fiber-composite heat exchanger for AAAV uses, such as corrosion and/or erosion and EHD-induced working fluid decomposition, electromagnetic interference, and power conditioning and/or requirement problems, will be studied. While Phase I will demonstrate the technology in laboratory-scale test modules, it will provide the design information for full scale testing of the heat exchanger in Phase II and commercialization of the technology in Phase III of the effort.
