Abstract

On a swept vertical tailplane with infinite span tangential blowing over the shoulder of a deflected rudder is applied. For large rudder deflection angles the flow on the rudder is separated without blowing. A numerical study is conducted with the aim to increase the side force coefficient which might be required for a take-off condition if a one-sided engine failure occurs. With a continuous slot and sufficient mass flow rate the separation on the rudder can be reduced or avoided. It is shown that by using discrete slots this can be achieved for a similar side force coefficient gain with a smaller momentum coefficient. In addition the sweep angle of the incoming flow is varied showing a strong impact on the achievable side force coefficient. This is also true for the curvature of the rudder shoulder over which the jet is blown.
