Electric power is efficient and reliable. Electric motors can be placed anywhere on the plane to improve efficiency
An Italian Tecnam P2006T aircraft will be modified with an electric propulsion system. NASA will compare data from the Tecnam to the X-57 to measure efficiency.
Batteries power everything from your cell phone to equipment on the International Space Station! The X-57 uses rechargeable lithium-ion batteries.
The X-57 aircraft uses 12 small motors located across the wing to increase airflow so that the wing produces lift even when the aircraft is flying slowly.
