In response to the growing aviation demands and the concern of environment and energy usage, hybrid/turbo-electric propulsion systems have been proposed by NASA. In this new concept, high power-density (specific power) and high-efficiency electric machines and power conditioning equipment (power electronics converters), and energy storage devices are the critical components that determine the success of this future aero- transportation architecture. NASA’s technical specifications for this future hybrid/turbo-electric propulsion system...
