Cover Story: As the aerodynamic characteristics of delta wings depend greatly on the state of the leading-edge vortex, its manipulation is of great interest for extending the flight envelope of such wing configurations. One efficient method of active flow control is applying pulsed blowing at the leading edge. The generated unsteady jets in-teract with the shear layer, altering the process of discrete vortex generation and, consequently, the mean flow field. Up to stall, pulsed blowing delays breakdown but has little influence on the aerodynamic coefficients. At post-stall, the actuation reattaches the shear layer and contributes to a significant lift increase.
