THE CURRENT TRENDS IN STRUCTURAL HEALTH MONITORING IN AEROSPACE APPLICATIONS

Abstract

This paper presents some general aspects about a new technique used, in aircraft industry, for determining the state of structural health. The Structural Health Monitoring method supposes the detailed observation of a structure using intelligent sensors, a performed acquisition system and a smart algorithm for data processing, the extraction of the damage feature and finally the statistical analysis of these data. An optimum SHM system should be able to indicate the damage type, its location and to predict the residual life of a specific structure. There are presented some current sensing method used in SHM systems for the aerospace applications. Also, it is shown the basic principle for the developing a smart algorithm for SHM systems and the two assumptions that were lead to the introduction of this new monitoring method in aerospace and civil area.
