Abstract/Summary Through-life management of aircraft structural integrity (ASI) is an important program in both civilian and military aviation providing structural safety, improvements in aircraft availability, and reduced cost of ownership. One innovative method for life extension is rework shape optimisation to minimise stresses at crack prone regions in metallic airframe components. This paper covers the collaborative work carried out between ASI-DGTA and AVD-DSTO in developing and transitioning the shape optimisation technology to manage and improve ASI within a regulatory environment. It is shown that numerical methods based on structural mechanics, can be used to develop robust and practical optimised rework shapes. Key lessons learned are discussed, including indicative results for the interaction of some key design parameters on peak stresses and predicted fatigue lives. Finally strategies for the application and transition management of this technology are given.
