Event Recognition for Realistic Load Spectra and their Impact on Inspection Intervals in Damage-Tolerant Design

The damage tolerance behaviour for two fuselage locations is investigated. Parametric studies are performed, revealing the influence of geometry onto the inspection intervals. For a circumferential crack in the upper fuselage, the influence of multiple different flights onto the inspection intervals is investigated. Results may be used both, in preliminary aircraft design as well as structural optimisation.
