A compliant root structure for connecting an airfoil to a fuselage structure capable of dampening the dynamic response of the fuselage structure when the airfoil encounters abrupt aerodynamic loads due to a turbulent atmosphere. The compliant root structure includes a connecting arm(s) that pivotally connects the airfoil to the fuselage structure so that the airfoil can displace relative to the fuselage structure in the direction relatively perpendicular to the spanwise and chordwise axes of the airfoil. A restoring force can be provided by the compliant root structure (for example, by spring means) to the airfoil when it is displaced relative to the fuselage. In some embodiments, the connecting arms can exhibit relatively high flexibility, and can be adapted to interconnect the airfoil and the fuselage by means of rigid joints. The flexibility of these connecting arms may eliminate the need for a separate spring means.
