Vortilon 翼下涡流产生装置 翼刀
Vortilons are fixed aerodynamic devices used to increase lift and reduce stalling at low speeds. They consist of one or more flat plates attached to the underside of the wing near its leading edge, roughly parallel to normal airflow. They function as vortex generators, and these vortices restrict airflow along the length of the wing. The can also be used to improve low speed aileron performance. The pylon used to mount jet engines under the wing produces a similar effect. Vortilons may be preferred to wing fences as producing less drag at higher speeds.Vortilons were introduced in the McDonnell Douglas DC-9 to overcome deep stalling issues. They have been used on a number of subsequent aircraft, including:
[*]BAe 125 1000 series
[*]Hawker 800XP
[*]Embraer ERJ 145 family
[*]Learjet 45
[*]Aériane Swift
