Abstract
The invention relates to a wing for an airplane having at least two winglets, wherein a local angle of attack at the upstream winglet shall be reduced by a passive elastic morphing in heavy load conditions and wherein stall shall occur for the downstream winglet, then. Both serves for limiting and reducing the forces and torques produced by the winglets.
