    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.

    摘要: A monitoring system for use with a turbine engine is described herein. The turbine engine includes a compressor and at least one compressor bleed valve coupled to the compressor. The monitoring system includes at least one sensor that is for sensing an operational parameter of the compressor bleed valve, and a controller that is coupled to the sensor and the compressor bleed valve. The controller is configured to determine an operating mode of the turbine engine and receive a monitoring signal indicative of the sensed operational parameter. The controller is also configured to calculate at least one operational value of the compressor bleed valve based at least in part on the sensed operational parameter. The controller is further configured to determine a condition of the turbine engine based at least in part on the calculated compressor bleed valve operational value.
