Safety concerns and resource limitations behind the conclusion of the project that saw many achievements thus far.
is yet another example of how X-planes help improve technological know-how. The X-57 was designated in 2016, with its first flight planned for 2017. NASA's original plan for the aircraft included multiple small electric motors to drive small propellers placed along the length of the aircraft's wing.
The aircraft was made by modifying an Italian Tecnam P2006T with an electric propulsion system to compare the data generated to conventional combustion engines.NASA's plans for test flights faced multiple setbacks from time to time. However, this also allowed the agency to improve the technology required for electric flight.
For instance, the discharge of the battery during the operation of the aircraft led to overheating installed on the plane would heat up during discharge and required NASA's engineers to redesign it from eight to sixteen modules and use aluminum honeycomb separators. NASA also had to scale back on the number of propellers on the aircraft wing eventually to just two. The issues of heat generated by the propellers also led to the design of the cruise motor controllers. These controllers were equipped with silicon carbide transistors that have 98 percent efficiency, which minimizes the heat generated and helps in quicker cooling of the electric motors.
The achievements from the project, such as the design and development of filters to block electromagnetic interference from electric propulsion, have been extensively published in research journals.
