  • Patent number: 10139376
    Abstract: A system to monitor a composite system component may include a plurality of sensors mounted proximate to the composite system component. A signal processing unit may receive, from each of the plurality of sensors, a series of sensed values associated with the composite system component and determine a kurtosis value for each series of sensed values. A threshold exceedance detector may detect if at least one of the kurtosis values exceeds a pre-determined threshold value. A delamination location estimation unit may calculate an estimated location of a composite system component delamination alert signal based on calculated time difference delay values of detected signal impulses in the series of sensed values using at least four of the plurality of sensors. A delamination alert output may then transmit a composite system component delamination alert signal, along with the estimated location, when at least one of the kurtosis values exceeds the pre-determined threshold.
