Reliability Oriented Optimisation of Structural Replacement Strategies for Aircraft Structures

Objective

Smart structures, which incorporate structural health monitoring (SHM) systems into mechanical components to enable online damage detection, have a strong potential to reduce inspection and maintenance cost of aircraft structures, while simultaneously maintaining or increasing the level of safety. At present, these technologies are still in the R&D phase and significant efforts are required before smart structures will become the industry norm.

One of the research needs concerns planning of inspection and maintenance for such structures. To be able to fully exploit the capabilities of novel monitoring technologies, it is indispensable that tools are developed to plan maintenance strategies for given safety philosophies (fail-safe, safe-life, damage tolerance) taking into account information obtained from SHM.

The goal of this project proposal is to develop a methodology and corresponding software algorithms for this task. Taking basis in the renewal theory as part of the general Bayesian decision analysis framework, tools for the life cycle optimisation of inspection/maintenance activities will be developed. Based on the commercial Strurel software code for reliability analysis developed and owned by the consortium leader the software tool shall be able to assess the effect of different strategies on safety and cost and thus enable the identification of optimal maintenance strategies subject to constraints on safety. The methodology will be applied to a stiffened panel provided by the ITD.
