System for sensing and locating delamination

A computerized method to monitor a composite system component, comprising:

• receiving by a signal processing unit a series of sensed values, associated with the composite system component, from each of a plurality of sensors mounted proximate to the composite system component;
• determining by the signal processing unit a kurtosis value for each series of sensed values;
• detecting, by a threshold exceedance detector, if at least one of the kurtosis values exceeds a pre-determined threshold value;
• calculating, by a delamination location estimation unit, 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;
• and
• transmitting, via a delamination alert output, a composite system component delamination alert signal, along with the estimated location, when the at least one of the kurtosis values exceeds the pre-determined threshold.

A non-transitory, computer-readable medium storing instructions that, when executed by a computer processor, cause the computer processor to perform a method to monitor a composite system component, the method comprising:

• receiving by a signal processing unit a series of sensed values, associated with the composite system component, from each of a plurality of sensors mounted proximate to the composite system component;
• determining by the signal processing unit a kurtosis value for each series of sensed values;
• detecting, by a threshold exceedance detector, if at least one of the kurtosis values exceeds a pre-determined threshold value;
• calculating, by a delamination location estimation unit, 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;
• and
• transmitting, via a delamination alert output, a composite system component delamination alert signal, along with the estimated location, when the at least one of the kurtosis values exceeds the pre-determined threshold.
