Method to produce a turbomachine blade |
摘要 |
The blade making process involves welding or soldering a metal felt fabric (3) onto the sheet (2) forming the shell structure (1). After this, the sheet and fabric unit is deformed by hydraulic pressure or by high internal pressure to form the blade shell structure. The composite material forming the bearing structure (6) is then inserted into the cavity. |
