The development of a V-shaped fuel-efficient airplane design known as the Flying-V will be funded by Dutch national carrier KLM Royal Dutch Airlines.

To improve the sustainability(持續性)of air travel,the Flying-V was developed by researchers at Delft University of Technology in the Netherlands,also known as TU Delft.

Its futuristic(未來派的)design puts the passenger cabin into the wings.It's said the plane will use 20% less fuel than the Airbus A350-900 while carrying a similar number of passengers.

“In recent years,KLM has developed as a pioneer in sustainability within its airline industry,”said Pieter Elbers,CEO and president of KLM.“We are proud of our progressive relationship with TU Delft.”

“Air travel is contributing about 2.5% of global CO2emissions (排放物),and the industry is still growing,so we really need to look at more sustainable airplanes,”said TU Delft project leader Roelof Vos.

“We cannot electrify planes,as electrified airplanes become too heavy and you can't fly people across the Atlantic on electric airplanes—not now,not in 30 years,” Vos said. “So we have to come up with new technologies that reduce fuel burning in a different way.”

“We've been flying traditional airplanes for decades now,but it seems like they are reaching the limit in terms of energy efficiency,”he said. “The new design actively contributes to the lift of the airplane,and creates less air drag.”

The plane's increased fuel efficiency is largely a result of its design,Vos explained.

The researchers hoped to fly a model this September,Vos said,while the new cabin design would be open to the public at Amsterdam Airport Schiphol in October.The completed plane is expected to enter service between 2040 and 2050.
