SEAL SUPPORT STRUCTURE FOR A CIRCUMFERENTIAL SEAL OF A GAS TURBINE ENGINE

摘要

A seal support structure (100) is provided for a circumferential seal (135). In one embodiment, the seal support structure includes an engine support structure (120), a seal support (122), and a shoulder (121) joining the engine support and seal support. The shoulder offsets the engine support from the seal support, and the shoulder and the seal support structure are configured to dampen vibration for the circumferential seal. The seal support structure may employ one or more dampening elements or materials to interoperate with a seal support structure to dampen vibration to a seal system.
