  • How do you see the future of flight? What is the shape of things to come?

  • How might jetliners be designed and powered?

  • Not just a few years from now. But decades.

  • These are some of the questions that NASA asked a Boeing-led team to examine.

  • [ Music ]

  • There was a time at a conference on advanced aircraft technologies where

  • somebody stood up and said, "What about electric airplanes?"

  • And everybody laughed. And that was only about five years ago.

  • So we sort of took that as a challenge.

  • Can we make an airplane that has electric motors and batteries actually work?

  • After looking at hundreds of ideas, one concept emerged as potentially viable and desirable.

  • The team calls it SUGAR Volt.

  • The SUGAR Volt is really similar to what people do with hybrid electric cars.

  • We have an engine that will operate on a combination of electrical power or conventional jet fuel.

  • So it plugs in at the airport, charges its batteries up, flies its mission.

  • SUGARstands for Subsonic Ultra Green Aircraft Research.

  • Voltsuggests that it would be drivenin at least in partby electricity.

  • The SUGAR Volt concept has twin engines that burn fuel in each engine’s core when great power is needed, such as takeoffs.

  • Then, to enable portions of the flight to be made with lower or even zero emissions,

  • it would use electricity to supplement or even replace power to the turbofans.

  • Were looking out to the 2030- to 2050-timeframeThe goals that were working to in the SUGAR study

  • are to reduce the amount of fuel burn by approximately 70% compared to what airplanes do today.

  • And, along with that, also be quieter and reduce the environmental impact of the air transportation.

  • [ Music ]

  • The SUGAR Volt’s long, thin wings are designed for greater lift and less drag.

  • So the aircraft would not only be more fuel-efficient, it would have shorter takeoffs and generate less noise.

  • To save space on the ground, the wings would also be designed to fold,

  • allowing use of the same airport gates that exist today.

  • The SUGAR Volt airplane combines a whole suite of technologies together.

  • It includes advanced aerodynamics. It has a better wing. It has a higher-span wing. It's more efficient. It has better propulsion.

  • But what the SUGAR Volt adds is it adds a hybrid electric approach.

  • Were defining the future of commercial air transportation.
