A rotor blade (44) is provided that includes an airfoil (100) having an airfoil shape (150). The airfoil shape (150) has a nominal profile substantially according to Cartesian coordinate values of X, Y, and Z listed in one of Table I, Table II, Table III, Table IV, Table V, Table VI, Table VII, Table VIII, or Table IX. The Cartesian coordinate values of X, Y and Z are dimensionless values of from 0% to 100%, which can be converted into dimensional distances expressed in distance units by multiplying the Cartesian coordinate values of X, Y and Z by a scaling factor of the airfoil expressed in distance units. The X and Y values define an airfoil profile cross-section at each Z value when connected by a smooth continuous arc. The airfoil profile sections at the Z-value smoothly engage one another to form a complete airfoil shape. 本发明提供了一种转子叶片(44)，该转子叶片包括具有翼型形状(150)的翼型件(100)。该翼型形状(150)具有基本上根据表I、表II、表III、表IV、表V、表VI、表VII、表VIII或表IX中的一者中列出的X、Y和Z的笛卡尔坐标值的标称轮廓。X、Y和Z的笛卡尔坐标值是从0％到100％的无量纲值，其能够通过将X、Y和Z的笛卡尔坐标值乘以翼型件的以距离单位表示的缩
