KLM Airlines Partners With University on Fuel-Efficient V-Shaped Passenger Plane Design
Every once in a while an experimental plane is displayed in an endeavor to present the innovative spirit of the organization building it, as part engineering experiment and part marketing project. The newest display is a university student’s design picked up by the national carrier KLM Royal Dutch Airlines.
In the news from CNN on Tuesday, KLM displays policies for the Flying-V aircraft, designed by Justus Benad of the Technical University of Berlin and developed furthermore by a research team at the Delft University of Technology. It looks a lot like a mixture between a stealth aircraft and a passenger jet, with the passenger seating, cargo hold, and fuel tanks all incorporated into the wide, V-shaped wings.
The Flying-V can have 314 passengers, just like the Airbus A350, although use 20 percent less fuel. Although it looks wide, the 213-feet width is well within standard airport infrastructure. The fuel efficiency comes from both the shape and the relatively light weight, said Roelof Vos, project leader at the Delft University of Technology.
"Aviation is contributing about 2.5 percent of global CO2 emissions, and the industry is nonetheless flourishing, so we really need to look at more sustainable airplanes," said Vos in a statement to CNN. "We cannot simply electrify the whole fleet, as electrified airplanes become way too heavy and you can't fly people across the Atlantic on electric airplanes — not now, not in 30 years. So we have to come up with new technologies that reduce fuel burn in a different way.”
Up to date, the university team has worked on making certain the fuselage shape actively strengthens the life of the aircraft. They have done mathematical testing and early wind tunnel tests so far, but are still working on creating a full-scale, flyable model. If that goes according to plan, it will see its maiden flight in September.
“We need to do much more testing in wind tunnels—high speed and low speed—to demonstrate that this airplane is efficient as we think,” Vos told CNN.
And if that doesn’t get off the ground, there’s always the marketing angle—a mock-up of the plane’s cabin will be open to the public at Schiphol airport in Amsterdam in October, to help ring in KLM’s 100th anniversary.
