    • An airfoil deicing system includes an airfoil substructure having an apex corresponding to the portion of the airfoil where the radius of curvature of the airfoil is smallest, the airfoil and the apex being bisected by a centerline, a deflectable shell disposed over the airfoil substructure for meeting and breaking an impinging airstream, a deflection means disposed between the airfoil substructure and the deflectable shell at the apex for deflecting the deflectable shell in the area of the apex away from the airfoil substructure and, at least one compressible zones provided beneath the deflectable shell adjacent the apex on either side of the centerline, the compressible zones facilitating deflection of the deflectable shell overlying the compressible zones toward the airfoil substructure when the deflection means deflects the deflectable shell.
    • 机翼除冰系统包括翼型底座,其具有对应于翼型部分的翼部的顶点,其中翼型的曲率半径最小,翼型和顶点由中心线平分,位于翼型子结构上方的可偏转壳,以满足 并且破坏冲击的气流,偏转装置设置在所述翼型底座结构和所述顶点处的所述可偏转壳体之间,用于使所述顶点区域中的所述可偏转壳体偏离所述翼型件底部结构,以及设置在所述可偏转壳体下方的至少一个可压缩区域 中心线两侧的顶点,当偏转装置偏转可偏转的壳体时,可压缩区域有助于偏转可压缩的壳体覆盖可压缩区域朝向翼型件子结构的偏转。
