A silencer duct 102, 202, 302 that may be part of, for example, a turbomachine 10 inlet and may include a duct body 104, and a silencer element 124 extending axially through the duct body 104. A first portion of a coupler 106 may extend axially from a first side 110 of the duct body 104. A second portion 112 of a coupler may extend axially from a second side 116 of the duct body 104. At least one of the first portion of the coupler and the second portion 112 of the coupler are configured to couple to at least one of an adjacent silencer duct 102, 202, 302 and an inlet.
摘要:
A silencer panel (104, 204) section may include an acoustic absorbing material (110, 210), a first enclosure (112, 212) surrounding the acoustic absorbing material (110, 210), and a First coupler (270) configured to couple the first enclosure (112, 212) to a second enclosure (212B) of an adjacent silencer panel (104, 204) section. A silencer panel (104, 204) may employ a plurality of the sections coupled together to form a single silencer panel (104, 204). A silencer duct (202) may include a frame (102, 206) forming a working fluid flow path, and a plurality of silencer panel (104, 204) mounts (280) positioned within the frame (102, 206), each silencer panel (104, 204) mount (280) configured to slidingly receive a silencer panel (104, 204), such as the silencer panel (104, 204) described herein.
