Method for manufacturing balancing weight for rotary base structure of turbomachine e.g. gas turbine used in aircraft engine, involves forming open profile for base structure of metal sheet by reshaping base structure of metal sheet

摘要

The method involves forming open profile for base structure of metal sheet by reshaping a base structure of metal sheet. The base structure of metal sheet is bent into U-shaped profile. Two legs (14,16) and bar (18) are provided in U-shaped curved metal sheet profile. The legs are funnel shaped and are extended at the base of bar. Independent claims are included for the following: (1) balancing weight; and (2) rotary base structure.
