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 support assembly for externally adjusting an inner casing with respect to an outer casing for a turbomachine includes a carrier plate, a carrier block that is fixedly connected to the carrier plate, a restrictor block fixedly connected to the carrier plate, a rod coupled to the carrier plate, and a plate threadably connected to the rod. The carrier block includes an inclined side and a carrier side. The restrictor block includes a restrictor side and an inclined side. The restrictor side is generally oriented towards the carrier side. A vertical gap for receiving a support arm of an inner turbine casing is defined between the restrictor side and the carrier side. The plate may be rotated about the rod to cause simultaneous movement of the rod, the carrier plate, the carrier block and the restrictor block, thus adjusting the inner casing with respect to the outer casing.
