    • An integrally bladed rotor for a gas turbine engine includes a hub, a plurality of blades radially extending from the hub and being integrally formed therewith. The hub having a rim from which the blades project and a pair of axially opposed split hub members extending at least radially inward from the rim. Each of the split hub members has a radially outer flex arm portion extending form the hub and a radially inner moment flange portion. At least one moment inducing element separately formed from the hub is mounted axially between the opposed split hub members and acts on the moment flange portions of the opposed split hub members to generate an inward bending moment on the flex arm portions of the opposed split hub members during rotation of the rotor, thereby deflecting the rim and the blades of the rotor radially inwardly.
    • 用于燃气涡轮发动机的整体叶片转子包括轮毂,从轮毂径向延伸并与其一体形成的多个叶片。 所述轮毂具有叶片从其突出的边缘,以及一对轴向相对的分开的轮毂构件,其至少从轮缘径向向内延伸。 每个分离轮毂构件具有从轮毂延伸的径向外部柔性臂部分和径向内侧力矩凸缘部分。 从轮毂分开形成的至少一个力矩引导元件被轴向地安装在相对的分开的轮毂件之间并且作用在相对的分开轮毂件的力矩凸缘部分上,以在相对的分开轮毂构件的挠性臂部分上产生向内的弯曲力矩 在转子旋转期间,从而使转子的轮缘和叶片径向向内偏转。

    • The present invention relates to a method for building centrifugal radial stages of turbines, in which the first and the second end of each blade (4) are connected to respective two support rings (2, 3) joining, by means of laser welding, at least a first semi-portion (10) belonging to the respective end of the blade (4) to a respective second semi-portion (10) belonging to the respective support ring (2, 3) so as to form a resilient yielding connecting portion (10, 15) along a radial direction, and providing at least a stop portion (11) belonging to the end of the blade (4) facing, along the radial direction, at least a stop element (14) of the respective support ring (2, 3). The resilient yielding connecting portion (10, 15) enables the strop portion (11) to enter into contact with the stop element (14) when the stage (1) is subjected to the functioning loads of the turbine.
    • 本发明涉及一种用于建造涡轮机的离心径向级的方法,其中每个叶片(4)的第一和第二端连接到相应的两个支撑环(2,3),所述两个支撑环通过激光焊接在 至少一个属于所述叶片(4)的相应端部的第一半部分(10)到属于相应的支撑环(2,3)的相应的第二半部分(10),以便形成弹性屈服连接部分 (10,15),并且至少提供属于所述叶片(4)的端部的至少一个止动部分(11),所述止动部分沿着所述径向方向面向所述相应支撑环的至少一个止动元件(14) (2,3)。 当舞台(1)承受涡轮机的功能负载时,弹性屈服连接部分(10,15)使得脚蹬部分(11)能够与止动元件(14)接触。

    • A turbine blade having a preestablished rate of thermal expansion is attached to a turbine disc having a preestablished rate of thermal expansion being greater than the preestablished rate of thermal expansion of the turbine blade and forms a turbine assembly. The turbine blade has a root portion defining a pair of sides having a pair of grooves therein. The turbine assembly includes a pair of flanges between which the turbine blades are positioned. Each of the pair of flanges has a plurality of grooves defined therein. The grooves within the pair of flanges are aligned with the grooves in the blades and have a space formed therebetween. A plurality of spherical balls are positioned within the space. The plurality of spherical balls has a preestablished rate of thermal expansion being equal to the preestablished rate of thermal expansion of the turbine blade.
