Abstract

 
 
 This work focus on the structural health monitoring of aircrafts parts specimen structures made of 2024 Aluminum alloys. In this paper we demonstrate the feasibility of a new non destructive control method capable to probe very large structures within a short time. The method we developed is based through a wide piezoelectric sensors network on a smart comparison between two acoustic signatures: the healthy structure response captured before the commissioning of the plane and “an after flight” response. The sensors network exploits the capability of piezoelectric patches to generate/measure specific Lamb wave’s modes. The system is therefore dynamically configured to localize mechanicals flaws using an algorithm that operates using different techniques like pitch-catch and pulse-echo.
 An analytic study is performed and tests to prove the proposed method feasibility on corroded structures specimens are provided at the end of this paper.
