The flow around the Leonardo Next-Generation Civil Tiltrotor aircraft (NGCTR-TD) is examined in the European research programme CleanSky AFC4TR ‘Active Flow Control for Tilt-Rotor aircraft” N° 886718, with the main objective to investigate the use of Active Flow Control Zero Net Mass Flux (ZNMF). This work focuses on the optimization of different parameters such as the frequency of actuation, the velocity, the angle of the jet and the dimensions of the actuators to better reattach the flow through the enhancement of the mixing and momentum transfer within the boundary layer to explore the capabilities of the AFC applicability to a full-scale VTOL aircraft.
