Comparative reliability analysis of electric aircraft versions for NASA’s X-57 based on Lz-transform method

Journal of Physics: Conference Series
Abstract As the goals of air transport shift towards more-electric or all-electric airplanes, different drive train configurations have been explored recently. A major goal on the way towards the inclusion in commercial air traffic is high reliability. One of the experimental electric airplanes is NASA’s X-57 “Maxwell”, which consists of
