“…Montazer et al [10] optimized the position and frequency of a synthetic jet using the Response Surface Methodology. More recently, the authors investigated two-dimensional active control using different blowing strategies similar to piezo-actuators embedded in the flap of a high-lift system [11][12][13]. The active flow control was combined with a morphing flap through cambering, which led to large flow separations on the suction side of the flap and a decrease in aerodynamic efficiency.…”

The study described in this paper was conducted as part of the European Funded CleanSky2 project AFC4TR (Active Flow Control for Tilt-Rotor aircraft). High-Fidelity numerical simulations were made to study various approaches of using Active Flow Control (AFC) actuators to delay flow separation at near stall conditions of the Next Generation Civil Tilt Rotor (NGCTR) VTOL aircraft with a tilted nacelle used during take-off and landing. The study revealed that for this configuration the flow separations travel in the spanwise direction starting from the middle of the wing. Various flow control strategies using Zero Net Mass Flux (ZNMF) actuators (synthetic jets) were then tested. Different number of actuators were integrated on * Postdoc,

This paper discusses the physical dynamics of the use of the Active Flow Control (AFC) actuators embedded in a Vertical Take-Off and Landing (VTOL) aircraft. Results of High-Fidelity numerical simulations are examined at near stall conditions. Different approaches of AFC are proposed to suppress the flow separation at these conditions. First the flow around the VTOL aircraft at high angle of attack in the take-off and landing configurations in real flight conditions at high Reynolds number are examined, then different flow control strategies are investigated. It was found that at these flow condition a flow separation travels along the spanwise direction in the near trailing-edge region of the wing with additional corner vortices between the wing-nacelle and the wing-fuselage junctions. Zero Net Mass Flux (ZNMF) actuators, also called synthetic jets, were then used for Active Flow Control. It was found that these ZNMF devices, when operating at the optimal blowing velocity and activation frequency, and when placed at the correct location enable the flow to re-attach and to delay the flow separation, resulting in an increase in aerodynamic efficiency of the aircraft. This work presented in this paper has been carried out in the context of the European project CleanSky2 Active Flow Control for TiltRotor aircraft (AFC4TR), Grant Agreement 886718.
