The invention relates to an airfoil of an aerodynamic surface, the airfoil comprising: a control surface comprising an upper surface and a lower surface; and an actuation device configured to raise or lower the control surface, and wherein at least a portion of one of the upper and lower surfaces of the control surface is auxetic, having a negative Poisson's ratio, and the other of the upper and lower surfaces of the control surface comprises a material having a higher Poisson's ratio. The invention also relates to an aerodynamic surface comprising at least one such airfoil.

    本发明涉及一种气动表面的翼型件,该翼型件包括:控制表面,该控制表面包括上表面和下表面;以及致动器件,该致动器件被构造成升高或降低该控制表面,并且其中该控制表面的上表面和下表面中的一者的至少一部分是拉胀性的、具有负泊松比,并且该控制表面的上表面和下表面中的另一者包含具有更高泊松比的材料。本发明还涉及包括至少一个上述翼型件的气动表面。
