Abstract

Experimental buffeting and gust alleviation response results are presented for a sweptback flat wing model using piezoelectric actuators to control bending and wing tip camber shape. Model response was sensed by strain gages, accelerometers and piezoelectric sensors. The open-loop and closed-loop results of this experimental study show that piezoelectric actuation is effective in attenuating vibration and the wake-induced buffet response over the range of parameters investigated. The airfoil camber shape control increases remarkably the efficiency of the system, by using a controlled change of lift in order to produce the required bending moments.
