| 发明名称 | Sound attenuating chimney element for a turbomachine system | ||
| 摘要 | A sound attenuating chimney element for a turbomachine system includes a high density outer body having an external surface and an internal surface, and one or more acoustic attenuation layers provided on the external surface of the outer body. The one or more acoustic attenuation layers include an outer surface portion and an inner surface portion. A structural layer is provided on the outer surface portion of the one or more acoustic attenuation layers. The structural layer includes an external surface that defines a duct configured and disposed to pass gases from the turbomachine system. | ||
