Fail-safe design optimization of an aircraft fuselage-wing section using the DamageCreator software

Abstract

[Abstract] Fail-safe design in aerospace is often addressed by the use of envelopes of possible damaged configurations when there is uncertainty about the size or location of the damage. This strategy leads to oversized designs, since realistic damage scenarios are not considered. In a previous research, we developed the DamageCreator software to automatically generate a large set of damaged FE meshes representing real accidental situations, coming from uncontained engine failures or propeller blade failures. This paper aims to perform a fail-safe optimization of a industry-like aerospace structure using realistic damaged scenarios automatically generated by the DamageCreator tool. A real historical accident database will be taken as input to generate the set of damaged configurations.
