Damped combustion cowl structure |
摘要 |
A method is provided for increasing the contact area between a damper wire and a sheet metal component in a combustion cowl of a gas turbine engine. This increase in contact area reduces the wear rate on the combustor cowl. A first curl is formed in the sheet metal component. A damper wire is situated to have a common contact area with the sheet metal component within the first curl. The first curl is die-formed around the damper wire before applying a heat treat operation to the structure. A final die-form closes the sheet metal curl around the damper wire.
