- The aircraft is powered by two 400-pound lithium-ion battery packs in the cabin that contain 23 kilowatt hours of power.
- NASA has published its research, procedures, designs, and technology from the X-57 development project online for different industry developers such as urban air mobility designers to use.
- The aircraft is being used for technology research and won't be available for commercial use.
- The X-57's first test flight will occur later this year on an unannounced date.

NASA has developed an experimental fully electric plane with 14 motors on its wings. Take a closer look at the X-57 Maxwell.
NASA has created the X-57 Maxwell, a fully-electric experimental aircraft with 14 motors on its wing.
NASA has created the X-57 Maxwell , a fully-electric experimental aircraft with 14 motors, all on its wing.
The Maxwell falls under NASA's X-plane "experimental planes" category and is the first piloted X-plane in 20 years. NASA's principal investigator Sean Clarke told Business Insider that this two-decade gap is because several X-plane aircraft that NASA has developed over the last 10 to 20 years have been autonomous.
The decision to put a pilot in the Maxwell came because NASA's test pilots are "high performance and [NASA gets] so much benefit from having them in the seat," Clarke said. Having pilots on the aircraft simplifies its design because the pilot can spot and diagnose issues while operating the aircraft.
However, NASA didn't build the X-57 body: an Italian Tecnam P2006T served as the starting point for the Maxwell. NASA then tested and outfitted through multiple modification series the P2006T with new batteries, instruments, smaller wings, and electric motors instead of the traditional double-piston engines.
The inspiration for the X-57's "Maxwell" nickname came from a 19th-century physicist who specialized in electromagnetism: James Clerk Maxwell.
NASA decided to embark on this X-57 Maxwell project as it started seeing an increase in accessibility to light yet "reliable" motors and motor controllers, according to Clarke.

"We [started] to think of using [these technologies] in an interesting way to redesign how an aircraft could behave," Clarke said.

Furthermore, NASA wanted to figure out how to move an aircrafts propulsion system to a different location while also altering its wing to give the aircraft a fast but efficient cruise speed.

The electric propulsion capabilities were crucial because the X-57 has multiple motors on its wingtips. A fuel-powered engine would have been too heavy, intricate, and unreliable to place on the wings, according to Clarke.

Because the X-57s wings are optimized for "high-performance cruising", it needs help for take-off and landings. This was done by spreading 12 small "high-lift" motors along the wing, giving the X-57 a total of 14 motors: 12 small motors and two larger cruise motors, all on the wingtips.

NASAs theory is that the 12 wingtip motors will also work with the airfoil to give the aircraft lift while reducing its drag. This is done by recovering energy that would otherwise be lost in the vortices that naturally form around the wingtip.

The propellers on the X-57 spin in the opposite direction of the vortices, therefore increasing the aircrafts propeller performance, according to Clarke. In total, the X-57 has a 500% increase in "high-speed cruise efficiency."

The electric propulsion system free of any greenhouse gases will also save an average of $165 annually compared to a combustion engine, according to NASA. It will also decrease the hourly operating cost of energy from 45% to just 9%.

Besides testing new technology, the X-57 allows NASA to test an aircraft with decreased noise and fuel emissions. However, the X-57 will likely only serve as NASAs "technology research platform" because there arent many commercial uses for a plane that only has one seat while the rest of the cabin is occupied by the instruments and batteries, according to Clarke.

However, the technology and research that has gone into developing and creating the X-57 can be used by the public, especially in the urban air mobility development industry.

In fact, its even encouraged: NASA has published its research, procedures, designs, and technology from the X-57 development project online for different industry developers to use.

NASA is also using the X-57 as a platform to participate in ASTM International "certification activities" so that the work done on the X-57 can be used to create standards for electric aircraft, according to Clarke.

The X-57 is currently at NASAs Armstrong Flight Research Center in Edwards, California and will be taking its first test flight sometime in the future. Clarke also said that NASA is now planning one or two more electric aircraft.
