We present a comprehensive parametric study on
the flow-control scheme denoted as wall-normal uni-
form blowing and suction in turbulent boundary lay-
ers around airfoils. The focus is primarily put on the
influence of the drag caused by the power consump-
tion of the support system. We also assess the theo-
retical background of the momentum budget includ-
ing free-stream and boundary-layer control flux. It is
shown that this assessment is crucial if a complete un-
derstanding and a reliable measurement of the drag in
such system is desired in practice.
