This latest version of the aircraft, called Modification II or Mod II, just arrived at Edwards from San Luis Obispo, California, where the plane was being developed by Empirical Systems Aerospace.
For Mod II, the typical combustion engines of the baseline aircraft have been replaced with electric cruise motors. And with the new engines, NASA can now begin the next phase of testing on the experimental craft, bringing it a step closer to reality.
The X-57 is based on a Tecnam P2006T aircraft. These twin-engined Italian aircraft are popular among aviators who own small, private planes. NASA planned out four rounds of modifications to take the plane from its base model to a completely electric aircraft. During Modification 1, the Tecnam P2006T’s two internal combustion engines were replaced with 14 electric motors. In the latest modification, Mod II, the batteries and instrumentation were updated. Now, NASA says they can move on to test flights. In Mods III and IV, engineers will keep developing the plane and conduct final tests, including on the wings.
Rebooting the NASA X-plane
By exploring technology in electric aircraft, NASA hopes to take a step toward eliminating the carbon footprint from flights. Currently, jet fuel emissions are a major contributor to Earth’s greenhouse gas problem. Throughout testing, NASA plans on sharing the information they learn about the electric plane with the larger industry as well.
X-planes, or experimental aircraft, have been a pillar of NASA’s aeronautics sector for a long time. In fact, NASA has been testing X-planes at the Armstrong Flight Research Center since the 1940s.
But most of the aircraft tested there have been focused on high speed flight. And while the X-57 won’t be fast, it will be NASA’s first crewed X-plane in two decades.
