Patent ID: 7607614

Claim:
An aircraft comprising: a fuselage; an airfoil comprising two wings fixed on either side of the fuselage, each wing being operably coupled to the fuselage by a fastening structure, the fastening structure forming a reinforcement at least one of an upper surface or a lower surface of the wing; a ventral fairing fixed to a lower part of the fuselage, the ventral fairing comprising a base and two panels extending radially relative to the base and rising laterally along the fuselage, each panel being provided with structure defining an opening for receiving a wing therethrough; a seal fixed to a periphery of each opening, the seal being at least partially positioned between an internal wall of the opening and the wing, wherein the seal is subjected to a difference in height along a transition zone defined between the fastening structure and the wing; wherein the aircraft includes, on at least one wing, a transition shim positioned in the transition zone between the fastening structure and the wing, a thickness of the shim decreasing from an edge of the fastening structure to the wing corresponding to the difference in height along the transition zone, thereby defining a slope of the shim, and wherein a profile of the shim restores an aerodynamic profile of the wing in the transition zone.
