An experimental investigation has been carried out on utilizing perpendicularly blowing/sucking synthetic-jet actuation (SJA), close to the trailing edge, for load control for wings, for e.g. reduction of fatigue loads. Hot-wire anemometry (HWA) measurements have shown that the developed SJA’s achieve maximum centerline jet velocities up to 45 m/s. At optimum actuation frequency of F+ = 10 (700 Hz) the lift coefficient is increased by 0.06 at 5 deg angle of attack.
