Abstract

An understanding of potential damage mechanisms, structural design criteria and fail-safe features, structural maintenance philosophy is needed in order to develop a sensor-based system to effectively monitor structural condition. The purpose of this paper is to review the primary aging mechanisms in current aging aircraft, identify a sensing and data management strategy to monitor aircraft structure, and describe analytical tools and technological development needed to implement structural health monitoring on commercial transport aircraft
