摘要： An airfoil for a rotor blade including an uncoated profile substantially in accordance with Cartesian coordinate values of X, Y and Z to facilitate balancing performance and durability of the rotor blade and to facilitate improving an operating efficiency of a high-pressure turbine is provided. The profile is carried only to four decimal places, wherein Y represents a distance from a platform on which the airfoil is mounted, and X and Z are coordinates defining the profile at each distance Y from the platform.

摘要翻译： 提供了一种用于转子叶片的翼型件，其包括基本上根据X，Y和Z的笛卡尔坐标值的未涂覆轮廓，以便于平衡转子叶片的性能和耐久性，并且有助于提高高压涡轮机的操作效率。 配置文件仅承载四位小数，其中Y表示与安装有翼型件的平台的距离，X和Z是从平台每个距离Y定义轮廓的坐标。
