Abstract: Methods and systems structural health monitoring system for a cyclically loaded structure are provided. The system includes a processor and a memory, and is configured to, in accordance with a data acquisition pattern: acquire raw sensed data from each of the N sensors; convert the raw sensed data into a data packet; store the data packet as a first data packet; acquire raw sensed data from each of the N sensors a second time and store the data packet as a second data packet; identify a scalar deviation between the first data packet and the second data packet; and transmit anomaly information to an external maintenance reasoner when the scalar deviation is determined to exceed a threshold. The data acquisition pattern incorporates a customer specific arrangement of a plurality of piezoelectric (PZT) sensors and sampling the sensors at predetermined angular locations on a circle of rotation associated with the structure.
