Active flow control to delay the flow separation on the rudder of two different models has been investigated in the ONERA L1 wind tunnel. The first model was used as a simplified test case to investigate different types of actuations and consisted of a flat plate with a rudder. The different types of actuation investigated were continuous/pulsed blowing through slots, continuous blowing through segmented slots, and sweeping jets. The lift increments of these different types of actuation were compared in terms of not only mass flow rate but also momentum coefficient and power coefficient. Then, active flow control by sweeping jets was selected to be tested on the second model, which is a scale vertical tail model of a generic business jet. Side force increments up to 80% were achieved with a 2% value of . Side force increments of 50% were also reached with a lower value of 0.5%. These side force increments could lead to a reduction of vertical tail plane wetted area and weight and consequently to a reduction of cruise drag and fuel consumption.
