Airbus has flown a test aircraft for the first time with its new transonic laminar wing that it hopes will reduce wing friction by up to 50 percent. The gain in aerodynamic efficiency would lower carbon-dioxide emissions by 5 percent, the company said. The Flight Lab test aircraft, an A340, flew for about three and a half hours in southern France on Tuesday. It’s the first test aircraft in the world to combine a transonic laminar wing profile with a true internal primary structure, Airbus said.
