Abstract
A method of improving performance of an aircraft, including attaching a wing tip to a wing of the aircraft. The wing tip includes a winglet and a ventral fin. The winglet includes a winglet leading edge, a winglet trailing edge, an adapter section, a transition section attached to the adapter section, a blade section attached to the transition section, and a first tip section attached to the blade section. The ventral fin is coupled to the winglet at an attachment location adjacent the transition section. The ventral fin includes a second tip section. The wing has a wing leading edge and a wing trailing edge in a wing chord plane. Attaching the wing tip to the wing includes connecting the adapter section to the wing such that the winglet leading edge continuously transitions from the wing leading edge, and the winglet trailing edge continuously transitions from the wing trailing edge.
