The “live-skin” actuation creates Travelling Waves (TW) on the flap, interacting with the flow instabilities along the shear layers and hence modifying its organization. This new morphing concept has been investigated in take-off configuration through experiments and numerical simulations on a near full-scale A380 wing prototype. A compromise was even experimentally found between lift and drag.
