NASA tested a similar concept. They call it Active Flow Control, or AFC.
A full-scale 757 tail, equipped with active flow control, has demonstrated increased rudder effectiveness in wind-tunnel tests by Boeing and NASA that could lead to smaller, lower-drag vertical tails.
"Sweeping jet" AFC actuators were mounted on one side of the fixed stabilizer, just upstream of the rudder hinge line to blow on to the leading edge of the deflected surface. The 37 actuators were supplied with variable mass-flow pressurized air from an external source and were individually addressable so that different spacings and zones could be tested.
Tail fins are huge to help compensate for engine failures. But with such system blowing pressurized air out of holes upstream from the rudder, manufacturers can design smaller tails to save on drag and weight.
Another system that works by suction (not blowing) at the leading edge is on the 787-9/10. It is used for both the horizontal and vertical stabilizers on the -9, but Boeing dropped the horizontal stabilizer system on the -10. There were plans to use it on the upcoming 777X, but Boeing dropped it. That system is called hybrid laminar-flow control (HLFC).
