摘要： Embodiments of the invention include an inspection system to inspect internal components of a compressor of a gas turbine engine. The inspection system includes an image recording assembly having one or more image recording devices, light sources, storage devices, and power supplies. The image recording assembly may be inserted into a compressor without removal of the compressor housing or disassembly of the compressor. The image recording assembly may be removably coupled to a rotary component of the compressor, e.g., a rotor blade, and used to record images of stationary components, e.g., stator vanes, of the compressor. The images may be inspected to identify wear and/or defects in the stationary components, e.g., stator vanes

摘要： A system for monitoring compressor anomalies includes an acoustic energy detector connected to the compressor and a controller in communication with the acoustic energy detector. The acoustic energy detector transmits an acoustic energy signal reflective of acoustic energy produced by the compressor to the controller. At least one sensor connected to the compressor measures an operating parameter of the compressor and transmits a parameter signal reflective of the operating parameter to the controller, A method for monitoring compressor anomalies includes sensing acoustic energy produced by the compressor and transmitting an acoustic energy signal reflective of the acoustic energy to a controller. The method further includes sensing at least one operating parameter of the compressor, transmitting a parameter signal reflective of the operating parameter to the controller, and transmitting an output signal based on the acoustic energy signal and the operating parameter signal.
