Title:
ロータの周囲に取り付けられるべき部品の質量の較正方法
Document Type and Number:
Japanese Patent JP4847788
Kind Code:
B2
Abstract:
The method involves removing a volume of material (46) in a zone of a platform (23) by machining with preset tolerance when positions of a longitudinal inertia axis (44) of the platform are known for bringing back the mass of the platform to a preset value. The platform is situated on one of inertia axis, where the volume of the material is removed by counter boring, milling and drilling. The volume of the material is determined by the difference between the mass of the platform and the preset value. An independent claim is also included for a turbine engine comprising rotor in which platforms are mounted in a periphery of the rotor.
