Abstract: A method for collecting acoustic data from an industrial machine is disclosed. The method may include: providing an unmanned aerial vehicle (UAV) having an acoustic receiver attached thereto; and positioning the unmanned aerial vehicle at a specific location so that the acoustic receiver collects acoustic data from the industrial machine at the specific location. An acoustic receiver is attached to the UAV for collecting acoustic data from the industrial machine. An acoustic filter is attached to the acoustic receiver and the UAV for filtering unwanted sound from the acoustic data. Acoustic data can be used by a flight control system to identify a specific location relative to the industrial machine that is a source a specific acoustic signature emanating from the industrial machine.

Abstract: An acoustic treatment assembly includes a fluid passage and a first panel disposed within the fluid passage. Additionally, at least a portion of a fluid flow through the acoustic treatment assembly is configured to flow across a first micro-perforated surface of the first panel. Further, the first panel includes at least one module, and each module of the at least one module includes the first micro-perforated surface and a respective back surface offset from the first micro-perforated surface opposite the fluid flow across the first micro-perforated surface. The first micro-perforated surface and the back surface form a first cavity configured to promote resonance within a first frequency range of the fluid flow.

Abstract: 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.

Abstract: A system includes an acoustic monitoring, analysis, and diagnostic system having a processor. The processor is configured to receive NF noise signals from a near field (NF) microphone array, the NF microphone array measures noises from a power generation system in a NF. The processor is configured to receive FF noise signals from a far field (FF) microphone array, the FF microphone array measures noises from a power generation system in a FF. The processor is configured to derive NF and FF noise measurements based on the signals and to synchronize the NF and FF noise measurements to create synchronized NF and FF noise data. The processor is configured to analyze the synchronized NF and FF noise data to create a NF and an FF noise signature. The processor is configured to diagnose root causes of noises generated from the power generation system and to report the root causes.
