Popis: The flow around the Leonardo Next-Generation Civil Tiltrotor platform (NextGenCTR or NGCTR) is examined in the context of the European research programme CleanSky AFC4TR Active Flow Control for Tilt-Rotor aircraft https://www.afc4tr.eu N 886718. The objective of the AFC4TR project is to investigate the use of Active Flow Control using pulsed air blowing devices with Zero Net Mass Flux (ZNMF) to control the vortical flow around wings. Three-dimensional simulations are carried out using the Navier-Stokes Multi-Block solver NSMB ([1], [2]) at high Reynolds number and near stall angle of attack of near stall condition corresponding to the take-off configuration. The flow is characterized by the presence of corner vortices formed in junctions located near the fuselage and the nacelle which results in a loss of the aerodynamic performances (decrease of lift, increase of drag). The flow is separated around the aileron and causes a considerable loss in its efficiency during the airplane maneuverability. This study examines these corner vortices using adapted turbulence models to capture their correct sizes. The rotation of the engine propellers is also considered due to the unsteady periodic effects produced on the pressure distribution of the wing and fuselage surfaces leading to an unstable evolution of these corner vortices. The study examines the effects of the Zero Net Mass Flux devices by producing a synthetic jet using a sinusoidal oscillating membrane or a piston to alternatingly force the fluid through an orifice into the external flow field. These devices (also known as synthetic jet actuators) do not require external fluid supply of complex piping, in addition to their low cost and small size. This work focuses on the optimization of different parameters as the frequency of actuation, the velocity amplitude, 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 Active Flow Control (AFC) applicability to a full-scale aircraft configuration at real flight conditions.
