Nasa, most prominent for its many Florida-launched exploits into space, on Friday showcased an early version of its first all-electric experimental aircraft, the X-57 ‘Maxwell’, at its lesser-known aeronautics lab in the California desert.Adapted from a Italian-made Tecnam P2006T twin-engine propeller plane, the X-57 has been under development since 2015 and remains at least a year away from its first test flight in the skies over Edward Air Force Base.But after attaching the two largest of 14 electric motors that will ultimately propel the plane — powered by specially designed lithium ion batteries — Nasa deemed the Maxwell ready for its first public preview.Nasa also showed off a newly built simulator that allows engineers, and pilots, to get the feel of what it will be like to manoeuvre the finished version of the X-57 in flight, even as the plane remains under development.The Maxwell is the latest in a proud line of experimental aircraft the National Aeronautics and Space Administration has developed over many decades for many purposes, including the bullet-shaped Bell X-1 that first broke the sound barrier and the X-15 rocket plane flown by Neil Armstrong before he joined the Apollo moon team.The Maxwell will be the agency’s first crewed X-plane to be developed in two decades.While private companies have been developing all-electric planes and hover-craft for years, Nasa’s X-57 venture is aimed at designing and proving technology according to standards that commercial manufacturers can adapt for government certification.Those will include standards for airworthiness and safety, as well as for energy efficiency and noise, Brent Cobleigh, a project manager for Nasa’s Armstrong Flight Research Center at Edwards, about 160km north of Los Angeles.“We’re focusing on things that can help the whole industry, not just one company,” he told Reuters in an interview at the research centre. “Our target right now is to fly this airplane in late 2020.”The final modification, or Mod IV, of the aircraft will feature narrower, lighter-weight wings fitted with a total of 14 electric engines — six smaller “lift” props along the leading edge of each wing, plus two larger “cruise” props at the tip of each wing.The lift propellers will be activated for take-off and landings, but retract during the flight’s cruise phase.Because electric motor systems are more compact with fewer moving parts than internal-combustion engines, they are simpler to maintain and weigh much less, requiring less energy to fly, Cobleigh explained.They also are quieter that conventional engines.One challenge is improving battery technology to store more energy to extend the plane’s range, with faster re-charging.Due to current battery limitations, the Maxwell’s design is envisioned for use in short-haul flights as an air-taxi or commuter plane for a small number of passengers.

Meet Maxwell X-57, Nasa’s first electric plane powered by 14 motors

NASA has showcased an early version of its first all-electric experimental aircraft X-57 Maxwell at its aeronautics lab in the California desert.


NASA on Friday showcased the X-57 Maxwell– an early version of its first all-electric experimental aircraft at its aeronautics lab in the California desert. The aircraft has been adapted from an Italian-made Tecnam P2006T twin-engine propeller plane and has been under development since 2015.








The Maxwell is the latest in the line of experimental aircraft NASA has developed over many decades. The others in the category include the bullet-shaped Bell X-1 that first broke the sound barrier and the X-15 rocket plane that was flown by astronaut Neil Armstrong before he joined the Apollo moon team. The Maxwell will be the agency’s first crewed X-plane to be developed in two decades.
At the moment, the X-57 Maxwell is at least a year away from its first test flight, however, NASA made the aircraft ready for its first public preview by attaching the two largest of 14 electric motors powered by specially designed lithium-ion batteries to propel the plane. Even though the X-57 remains under development, the space agency has made a simulator to allow engineers and pilots to get the feel of what it will be like to manoeuvre the finished version of the said aircraft.
For an electric aircraft, one challenge is to improve the battery technology in order to store more energy and extend the plane’s range. Due to current battery limitations, Maxwell’s design is envisioned for use as an air-taxi or commuter plane for a small number of passengers in short-haul flights.

NASA Unveils First Electric Plane X-57 "Maxwell", Hopes To Fly It By 2020

The Maxwell will be the agency's first crewed X-plane to be developed in two decades.
EDWARDS AIR FORCE BASE, Calif: 
NASA, most prominent for its many Florida-launched exploits into space, showcased an early version of its first all-electric experimental aircraft, the X-57 "Maxwell," on Friday at its lesser-known aeronautics lab in the California desert.
Adapted from a Italian-made Tecnam P2006T twin-engine propeller plane, the X-57 has been under development since 2015 and remains at least a year away from its first test flight in the skies over Edward Air Force Base.
But after attaching the two largest of 14 electric motors that will ultimately propel the plane - powered by specially designed lithium ion batteries - NASA deemed the Maxwell ready for its first public preview.
NASA also showed off a newly built simulator that allows engineers, and pilots, to get the feel of what it will be like to manoeuvre the finished version of the X-57 in flight, even as the plane remains under development.
The Maxwell is the latest in a proud line of experimental aircraft the National Aeronautics and Space Administration has developed over many decades for many purposes, including the bullet-shaped Bell X-1 that first broke the sound barrier and the X-15 rocket plane flown by Neil Armstrong before he joined the Apollo moon team.
The Maxwell will be the agency's first crewed X-plane to be developed in two decades.
While private companies have been developing all-electric planes and hover-craft for years, NASA's X-57 venture is aimed at designing and proving technology according to standards that commercial manufacturers can adapt for government certification.
Those will include standards for airworthiness and safety, as well as for energy efficiency and noise, Brent Cobleigh, a project manager for NASA's Armstrong Flight Research Center at Edwards, about 100 miles (160 km) north of Los Angeles.
"We're focussing on things that can help the whole industry, not just one company," he told Reuters in an interview at the research centre. "Our target right now is to fly this airplane in late 2020."
The final modification, or Mod IV, of the aircraft will feature narrower, lighter-weight wings fitted with a total of 14 electric engines - six smaller "lift" props along the leading edge of each wing, plus two larger "cruise" props at the tip of each wing.
The lift propellers will be activated for take-off and landings, but retract during the flight's cruise phase.
Because electric motor systems are more compact with fewer moving parts than internal-combustion engines, they are simpler to maintain and weigh much less, requiring less energy to fly, Cobleigh explained. They also are quieter that conventional engines.
One challenge is improving battery technology to store more energy to extend the plane's range, with faster re-charging.

NASA Unveils Experimental Electric Plane

NASA showed off its all-electric X-Plane, which will allow flight with no carbon emission. Gene Kang reports for the NBC4 News at 5:55 p.m. on Friday, Nov. 8, 2019. (Published Friday, Nov. 8, 2019)
NASA is developing a plane that may pave the way for greener air travel.
The NASA X-57 Maxwell plane--referred to as the X-Plane--is an all-electric experimental aircraft. Instead of fuel-powered turbine engines, the X-Plane gets its juice from lithium ion battery packs.
It can perhaps best be described as a Tesla with wings.
Brent Cobleigh, NASA Flight Demonstrations and Capabilities Project Manager, said the X-Plane serves as a glimpse into the future.
"To see the era of the Jetsons be something that’s potentially real is pretty exciting," Cobleigh said.
The X-Plane is currently in its Modification II configuration, and is one of three all-electric configurations being used to develop certification standards for electric aircraft markets.
Each of the lithium ion battery packs used in the plane weighs about 51 pounds, and the X-Plane uses about 800 pounds of battery packs in total to function.
"That battery can put in about the amount of power you need to power 100 average American houses," Cobleigh said.
The plane also features 14 electric motors and propellers, which allow for greater efficiency and zero in-flight carbon emissions. The aircraft’s electric components also alter the noise it emits, resulting in a softer, higher-pitched sound when compared to regular planes.
The X-Plane will begin air testing as early as next year when it is shared with the government and the airline industry.
