摘要： The present disclosure is directed to a sound attenuation system for a gas turbine engine. The sound attenuation system includes a compressor inlet casing having a compressor inlet casing inner surface and defining a compressor inlet passage extending therethrough. An inlet plenum body couples to the compressor inlet casing. The inlet plenum body includes an inlet body inner surface and defines an inlet plenum therein. One or more sound attenuating panels couple to at least one of the compressor inlet casing inner surface and the inlet plenum body inner surface of the duct. Each sound attenuating panel includes a first sheet defining a first plurality of apertures extending therethrough and a solid second sheet spaced apart from the first sheet.

摘要： A system includes a fluid distribution system. The fluid distribution system includes a first water wash nozzle configured to spray a wash fluid into an intake flow received through a bell mouth of a compressor during operation of the compressor in a water wash mode. The first water wash nozzle includes a first inlet end coupled to the bell mouth of the compressor, a first tip disposed opposite the first inlet end, and a first body of the first water wash nozzle extending from the first inlet end to the first tip toward an axis of the compressor. The first water was nozzle further includes a first outlet disposed at the first tip and configured to spray a first portion of the wash fluid into the intake flow during operation of the compressor in the water wash mode and a second outlet disposed along the first body and configured to spray a second portion of the wash fluid into the intake flow during operation of the compressor in the water wash mode.
