NASA Targets a Fivefold Gain in High-speed Energy Efficiency with X-57 Program
The electric-powered X-57 Maxwell prototype is NASA’s first manned X-plane experimental aircraft in more than two decades.
NASA started flight testing the first example of the X-57 Maxwell electric aircraft early in 2020 and expects to have four prototypes in test flights by early 2022. Its aim is to provide guidance for electric aircraft pioneers and also regulators.
