2017 ICMC Focused Symposia: Materials, Technologies, and Drivetrain Machines for Electric Propulsion Transportation
Electric-vehicle (EV) or hybrid-electric-vehicle (HEV) propulsion has been developed for almost all major transportation systems, including automobiles, large-scale trucks, trains, military and commercial ships, Formula 1 auto-racing, and other. Electric-propulsion has become a strong focus for the aerospace industry in recent years, in part because of many successful demonstrations of 2-4 passenger aircraft flying > 200 miles with 4-5x higher energy efficiency. For industries like aerospace that are especially sensitive to size-weight-and-power (SWaP), the development of cryogenic electric-power drivetrains is expected to provide significant advantages and system-level benefits. Superconducting/cryogenic technologies have been studied for many years for 0.1 MW to 50 MW-class electric power systems. Many recent strong advances in improving performance and technology development will be described in this symposia.
The 2017 CEC-ICMC conference is providing this focused symposia venue to consider all aspects of cryogenic electric-propulsion technologies, including drivetrain components/machines, cryogenic cooling and ancillary technologies, and system-level-integration issues and impacts. The sessions in this symposia will be of interest for different attendees, including engineers/scientists, system-level developers, and industry-level representatives. Sessions will include special-invited and contributed presentations, and topics of interest include, but are not limited to:
