NASA Glenn has repurposed its Hypersonic Tunnel Facility to create the NASA Electric Aircraft Testbed (NEAT), a reconfigurable facility that can accommodate power systems for large passenger airplanes, like a Boeing 737, with megawatts of power.

The testbed recently conducted its first megawatt-scale test. NEAT can simulate altitudes of up to 40,000 feet to test high-voltage power electronics, electric motors, and controls.
