Kurzfassung
Dynamic stall control using pulsed blowing is compared with control by constant blowing for an OA209 airfoil. Flow control was by blowing from 42 portholes, flush with the airfoil surface, of diameter 1% chord positioned at 10% chord and with separation 6.7% chord. Light stall at Mach 0.3 could be fully suppressed by constant blowing, and for deep stall a pitching moment peak reduction of 65% was seen. For the jet configuration and test cases investigated in this paper, pulsed blowing at 100-500 Hz was found to be at best as effective as constant blowing with the same mass flux for the control of dynamic stall.
