Abstract
A free wing aircraft including a free wing pivotally supported about a spanwise axis for flight in a free wing mode of operation with respect to the fuselage is disclosed. The free wing is capable of being deflected into a nose down configuration sufficient to create an aerodynamic braking effect to decrease air speed after landing upon roll-out. This aerodynamic braking effect can also be sufficient to create negative lift that plants the aircraft firmly down, increasing the coefficient of friction and allowing the aircraft brakes to be more effective relative to a fixed wing aircraft at touchdown.
