Tradeoff Analysis Tools for Hybrid NDE-SHM Life Management Strategies (Preprint)

Abstract

Hybrid life management strategies for new and aging aircraft have been proposed that combine traditional non-destructive evaluation (NDE) methods and recently developed structural health monitoring (SHM) technologies. In recent times, a usual aim for managing the life of aircraft components that are critical or that are subject to fatigue or corrosion damage is to attempt development of in situ damage detection systems that can indicate when more detailed inspection is necessary. This creates a need for decisions about the type and settings of sensors and signal processing algorithms for the health monitoring system, and system type, settings, and scheduling for NDE. How well these systems are matched will have great influence on overall maintenance cost, aircraft availability and system reliability. In this presentation, a software package is presented for integrating NDE and SHM design with product life management models.
