  • METHOD AND APPARATUS FOR MONITORING WIND TURBINE BLADES DURING OPERATION
    Publication number: 20140260634
    Abstract: A wind power turbine blade inspection system includes a sensor positioned on the blade root end bulkhead to receive airborne acoustic signals emanating from anomalies in rotating turbine blades during cyclic stress loading, a three axis accelerometer to determine the gravity vector and other sources of cyclic acceleration with respect to the acoustic signals and a signal analysis system configured to analyze the sensor and accelerometer signals to provide data for wind power asset management.
