Lamb-wave-based monitoring of the aircraft during full-scale fatigue experiment - results and conclusions
Abstract »In scope of the SYMOST project a turbo-prop military aircraft, monitored by a net of piezoelectric transducers, was subjected to a long-term full-scale fatigue experiment. Lamb waves excited by the sensor net were used for the detection and localization of fatigue damage. Several algorithms for Lamb wave signal processing and interpretation were implemented and tested in the project. This paper presents selected results of the full-scale fatigue experiment of the PZL-130 Orlik TC II Aircraft, including: four methods of temperature compensation for Lamb waves and diagnose obtained by ensembles of neural networks operating on groups of damage indices. Results of aircraft monitoring by means of different SHM methods over a period of one year are presented and commented. Different approaches to damage detection are compared in terms of their reliability and their limitations for practical applications.
