System for estimating a condition of a non-conductive hollow structure exposed to a lightning strike

摘要

A system (10) is provided for estimating a condition of a non-conductive hollow structure exposed to a lightning strike (18). The structure has an internal cavity (20). The system (10) includes a pressure transducer (22) to measure a pressure (23) of an acoustic wave (24) generated within the internal cavity (20) due to the lightning strike (18). The system (10) further includes a controller (26) coupled to the pressure transducer (22), to receive the measured pressure (23) from the pressure transducer (22), and to process the condition of the structure, based on the measured pressure (23).
