Recent patent approvals for Airbus show some....unique ideas on the airliner front. They're just patents so it doesn't mean they're going to build them, but they are very different.
Patent 8,157,204 filed in 2008, is for an updated double fuselage turboprop/open rotor aircraft.
The main advantage is that it reduces structural weight by reducing wing bending. According to the patent, it is supposed to overcome some of the limitations of Boeing Patent 4,165,058.
The second Airbus patent, 8,152,095, also filed in 2008, is for an "aircraft having a reduced acoustical signature. The engines are mounted on top of the fuselage, in an extended nacelle, with the intake in front of the trailing edge, and the exhaust between two vertical tails.
Meanwhile, Boeing has filed for an updated patent (2006) 8,016,223 for the Sonic Cruiser.
