...Amir Teimourian; Sebastian Altmeyer Purpose This paper seeks to examine the application of active flow control using a valve system in a new hole-down-array (HDA-2p) wing design. Design/methodology/approach The active valve system functions by opening and closing various apertures to regulate...

... stall and drag. This is solved via active or passive flow control. Active flow control method moving surface boundary (MSB) enhances shear flow momentum, making it effective. MSB is easier than suction and blowing. Asymmetrical airfoils, which generate lift in aircraft wings, have received less MSB...

...Petr Vrchota; Ales Prachar; Shia-Hui Peng; Magnus Tormalm; Peter Eliasson Purpose In the European project AFLoNext, active flow control (AFC) measures were adopted in the wing tip extension leading edge to suppress flow separation. It is expected that the designed wing tip extension may improve...
