An active winglet includes a body portion substantially parallel to a wing of an aircraft, as if it were an extension of the wing. The body portion is attachable to an aircraft wing and includes a controllable airflow modification device coupled thereto. By virtue of having a controllable airflow modification device, the winglet is capable of adjusting a control surface of the controllable airflow modification device in response to in-flight conditions, to reduce wing loads, increase range, and/or increase efficiency.


1. An aircraft comprising: a fuselage;a baseline wing, the baseline wing coupled to the fuselage at a first end of the baseline wing and having an aileron; anda winglet comprising: a horizontal portion coupled to a second end of the baseline wing, such that the horizontal portion is outboard of the baseline wing; anda controllable airflow modification device directly coupled to the horizontal portion, the controllable airflow modification device, comprising: a control surface disposed at a trailing edge of the winglet, such that the control surface is su...
