    • An active winglet includes a body portion substantially parallel to a wing of an aircraft, as if it were an extension of the wing, and an angled portion that projects at an upward angle from the body portion. 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 increase efficiency.
    • 活动小翼包括基本上平行于飞行器的机翼的主体部分,如同它是机翼的延伸部分,以及从身体部分以向上的角度突出的倾斜部分。 主体部分可附接到飞行器机翼并且包括耦合到其上的可控气流改变装置。 由于具有可控气流改变装置,小翼能够响应于飞行中的条件来调节可控气流改变装置的控制表面,以减少机翼载荷,增加范围并提高效率。
