Zusammenfassung:The present invention is related to an aerofoil (1) of an aerodynamic surface (10), the aerofoil comprising: a control surface (2) comprising an upper surface (2.2) and a lower surface (2.3), and an actuating means (3) configured to elevate or lower the control surface (2), and wherein at least a portion of one of the upper surface (2.2) and the lower surface (2.3) of the control surface (2) is auxetic with a negative Poisson ratio, and the other of the upper surface (2.2) and the lower surface (2.3) of the control surface (2) comprises a material with a higher Poisson ratio.
