Method for mass calibration of parts to be mounted in the periphery of a rotor

摘要

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.
