NASA to test faster, cleaner and quieter X-57 electric aircraft

| 2 comments

NASA is planning tests of an experimental electric aeroplane, which it believes could lead to reduced flight times and carbon emissions for future air travel (+ slideshow).

The X-57 aircraft will be used to test NASA's new electric propulsion technology – part of a wider ongoing shift towards electric aircraft.

NASA's X-57 electric aircraft will have 14 motors instead of two gas-fuelled engines

The space agency hopes that by distributing electric power across 14 motors integrated into the wings, the plane will require five times less energy to cruise at 175 miles per hour.

"Typically, to get the best fuel efficiency an airplane has to fly slower than it is able," said NASA in a statement. "Electric propulsion essentially eliminates the penalty for cruising at higher speeds."

X-57 could also lead to reduce flight times, noise, and operational costs for small aircraft

The technology used in the X-57 could also help to reduce flight times, noise, and operational costs – up to 40 per cent – for small aeroplanes.

"As most drivers of hybrid electric cars know, electric motors are more quiet than conventional piston engines," NASA said. "The X-57's electric propulsion technology is expected to significantly decrease aircraft noise, making it less annoying to the public."

NASA will build the plane by modifying an existing Italian-designed light aircraft, the Tecnam P2006T, replacing its two gas-fuelled engines with a long, skinny wings and 14 electric motors.

The 12 motors incorporated into the wings will be employed during take-offs and landings.

Two larger propellors on the tip of each wing tip will then be used to cruise at altitude. All of the motors will be powered only by batteries, eliminating all carbon emissions.

X-57, nicknamed Maxwell after 19th-century Scottish physicist James Clerk Maxwell, is part of NASA's decade-long New Aviation Horizons initiative. This will include the development of five larger X-planes with the end goal of commercial production.

Earlier this year, NASA also unveiled a conceptual design for a supersonic plane that would be much quieter than Concorde.

"NASA is working hard to make flight greener, safer and quieter – all while developing aircraft that travel faster, and building an aviation system that operates more efficiently," said NASA administrator Charlie Bolden.

Other recent developments in flight include a new luxury line of personal aircraft from Cobalt and the return of Virgin Galactic space flight testing.
