Abstract
A device for adapting aerodynamic characteristics of a wing element, includes a winglet, movably attachable to a wing element. The winglet or parts of the winglet may be rotatable in relation to the wing element such that an associated rotary axis with a main direction of extension of the wing element encompasses an angle that differs from an angle of 90°. In addition, a method is disclosed.
Claims22
An adaption device for adapting aerodynamic characteristics of a wing element, comprising:
- a winglet movably attachable to the wing element, wherein the winglet is attachable on an attachment axis to the wing element, such that the winglet is rotatable around the attachment axis as a rotary axis having a rotary axis direction, and an angle between the rotary axis direction and a direction of a main axis of extension of the wing element differs from 90°, wherein the direction of the main axis of extension is perpendicular to an axial direction along the axis of an aircraft fuselage to which the wing element is attached.
A method for adapting aerodynamic characteristics of a wing element, comprising the step of rotating on two rotary axes a winglet that is attached to the wing element in relation to the wing element such that an angle between one of the two rotary axes, having a first rotary axis direction and a direction of a main axis of extension of the wing element differs from 90°, wherein the direction of the main axis of extension is perpendicular to an axial direction along the axis of an aircraft fuselage to which the wing element is attached.
