Abstract
An aircraft includes a tiltwing where the tiltwing is a single wing to which starboard-side and non-foldable outer propeller, a port-side and non-foldable outer propeller, a starboard-side and foldable inner propeller, and a port-side and foldable inner propeller are coupled to. Those rotors rotate at least some of the time when the tiltwing is in a vertical takeoff and landing position. The starboard-side and foldable inner propeller and the port-side and foldable inner propeller are stowed at least some of the time when the tiltwing is in a forward flight position. The tiltwing rotates about an axis of rotation, when rotating between the vertical takeoff and landing position and the forward flight position, that is higher than the aircraft's center of mass.
