CONTROLLABLE AIRFLOW MODIFICATION DEVICE PERIODIC LOAD CONTROL

摘要

An active wing extension 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 multiple controllable airflow modification devices coupled thereto. By virtue of having multiple controllable airflow modification devices, the wing extension is capable of adjusting control surfaces of the multiple controllable airflow modification devices in response to in-flight conditions, to reduce wing loads, improve wing fatigue characteristics, increase range, reduce torsional loads, alleviate flutter, and/or increase efficiency.

主权项

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; and a wing extension 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 (CAMD) directly coupled to the horizontal portion of the wing extension, the CAMD being configured to alleviate a torsional load on a wing and to be controllable independently of the aileron.
