So one of the other designs that didn't get selected has just been given the X-57 designation.

NASA Hybrid Electric Research Plane Gets X Number, New Name
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.”

NASA Administrator Charles Bolden highlighted the agency’s first X-plane designation in a decade during his keynote speech Friday in Washington at the American Institute of Aeronautics and Astronautics (AIAA) annual Aviation and Aeronautics Forum and Exposition, commonly called Aviation 2016.

“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,” Bolden said.

As many as five larger transport-scale X-planes also are planned as part of the initiative. Its goals – like the X-57 – include demonstrating advanced technologies to reduce fuel use, emissions and noise, and thus accelerate their introduction to the marketplace.

The X-57 number designation was assigned by the U.S. Air Force, which manages the history-making process, following a request from NASA. The first X-plane was the X-1, which in 1947 became the first airplane to fly faster than the speed of sound.

“Dozens of X-planes of all shapes, sizes and purposes have since followed – all of them contributing to our stature as the world’s leader in aviation and space technology,” said Jaiwon Shin, associate administrator for NASA’s Aeronautics Research Mission Directorate. “Planes like the X-57, and the others to come, will help us maintain that role.”

Its original wing and two gas-fueled piston engines will be replaced with a long, skinny wing embedded with 14 electric motors – 12 on the leading edge for take offs and landings, and one larger motor on each wing tip for use while at cruise altitude.

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.

The X-57 research started as part of the NASA Aeronautics Research Mission Directorate's Transformative Aeronautics Program's Convergent Aeronautics Solutions project, with the flight demonstrations being performed as part of the Flight Demonstration Concepts project in the Integrated Aviation Systems Program.

I just saw some idiot at the gym put a water bottle in the pringles holder on the treadmill.

NASA Aims For Supersonic Airliners As Quiet As Subsonic

Quote
After minimizing sonic boom, reducing airport noise is seen as the next biggest barrier to commercially viable future supersonic transports. As it works toward flying an X-plane in 2019 to demonstrate low-boom design technology, NASA is conducting ground tests of an engine nozzle that could make a small supersonic airliner as quiet as current subsonic transports.

The model tests underway at NASA’s Glenn Research Center will validate design tools and concepts for an integrated propulsion system that would enable a quiet supersonic airliner with the seating capacity of a regional jet to have a cumulative noise level 10 EPNdB below current Chapter 4 limits.

Aurora D8: Nasa spending $2.9m to revitalise 'double bubble' subsonic twin-hull planes by 2027

Quote
Nasa has decided to invest $2.9m (Ł2.19m) in order to realise an innovative plane concept invented by MIT and Aurora Flight Sciences in 2008 which could make subsonic planes much more efficient than they are today.

The Aurora D8, which flies at a speed of Mach 0.764 (582 mph, 936 km/h), was originally developed by Aurora Flight Sciences and MIT as part of Nasa's N+3 Program, which provided funding of technologies for new aircraft that would be substantially more efficient to aeroplanes today, that would be put into service in the 2030s.
