Abstract:
1. A morphing airfoil system for an aircraft, the system comprising: a first non-planar airfoil having a first root, a first span, a first chord, and a first tip, the first airfoil being attachable to an aircraft near the first root; a second non-planar airfoil having a second root, a second span, a second chord, and a second tip, the second airfoil being attachable to the aircraft near the first root; and at least one movable connection attached to at least one of the first airfoil near the first root and the second airfoil near the second root, the movable connection being arranged to move at least one of the first airfoil and the second airfoil from a first position with the first tip and second tip near each other during a flight condition other than takeoff and landing to a second position with the first tip and second tip spaced apart from each other, during at least one of takeoff and landing.
