NASA SACD X-57 Maxwell

[Flyaway]

And here we have the first X plane in a decade, the X-57 nicknamed Maxwell.

With 14 electric motors turning propellers and all of them integrated into a uniquely-designed wing, NASA will test new propulsion technology using an experimental airplane now designated the X-57 and nicknamed “Maxwell.” This artist's concept of the X-57 shows the plane's specially designed wing and 14 electric motors. NASA Aeronautics researchers will use the Maxwell to demonstrate that electric propulsion can make planes quieter, more efficient and more environmentally friendly.

“With the return of piloted X-planes to NASA’s research capabilities – which is a key part of our 10-year-long New Aviation Horizons initiative – the general aviation-sized X-57 will take the first step in opening a new era of aviation,” said NASA Administrator Charles Bolden, during his keynote speech Friday in Washington at the American Institute of Aeronautics and Astronautics (AIAA) annual Aviation and Aeronautics Forum and Exposition.

NASA’s aeronautical innovators hope to validate the idea that distributing electric power across a number of motors integrated with an aircraft in this way will result in a five-time reduction in the energy required for a private plane to cruise at 175 mph.

Several other benefits would result as well. “Maxwell” will be powered only by batteries, eliminating carbon emissions and demonstrating how demand would shrink for lead-based aviation fuel still in use by general aviation.

Energy efficiency at cruise altitude using X-57 technology could benefit travelers by reducing flight times, fuel usage, as well as reducing overall operational costs for small aircraft by as much as 40 percent. Typically, to get the best fuel efficiency an airplane has to fly slower than it is able. Electric propulsion essentially eliminates the penalty for cruising at higher speeds.

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

Great document, thanks for sharing. Really shows just how massively more efficient electric designs are.

NASA X-Plane Gets Closer to Electric Flight

NASA's next X-plane, the all-electric X-57 Maxwell, is getting closer to its maiden flight. Engineers at Scaled Composites in Mojave, California, along with prime contractor on the program Empirical Systems Aerospace (ESAero), are preparing to integrate electric systems into a Tecnam P2006T to convert it to the X-57. The first electric version of the aircraft, known as Mod II, will replace the P2006T's gas-driven Rotax engines with electric motors and a battery pack to power the plane.

NASA Administrator Bill Nelson toured Armstrong last week, where he got an up-close look at the tiny two-seater aircraft. In an interview with The Verge, Nelson said that the technology that underpins the X-57 will be crucial in the effort to decarbonize the aviation industry.

“They’re getting ready to fly this,” Nelson said. “And it is the first demonstrator of an all-electric [airplane].”

NASA’s X-57 Maxwell is a step closer to flight readiness

NASA’s X-57 Maxwell all-electric aircraft reached another milestone toward its first flight with the successful thermal testing of its cruise motor controllers at NASA’s Glenn Research Center.

Well, that has changed a lot, regrettably:

Finalizing aircraft operations by September 2023 will not incorporate first flight of the X-57 aircraft. The project encountered several challenges to safe flight, including mechanical issues late into its lifecycle and a lack of availability of critical components required to develop experimental hardware. Given the approaching planned end of aircraft operations, the timeline would not allow the team to reach acceptable flight conditions.

X-57 Project Creates Paths Toward Electric Aviation

NASA’s X-57 Maxwell all-electric aircraft project will finish aircraft operational activities by the end September with documentation and close-out activities continuing for several months afterwards.

I wonder how many startups designing electric aircraft will run into similar issues with their projects. It shows just how tricky it is to design an aircraft with an innovative propulsion system.

Seems a bit foolish that this project ran out of funds and had to be shut down while NASA continues their pursuit of a low boom SST design even though the economics of supersonic flight makes it very unlikely we'll ever see a successor to Concorde. Considering that global warming and sustainability are issues that are here to stay, this project should have recieved better funding and support.
