Abstract. Over the years, the German Aerospace Center (DLR) has developed a multidisciplinary process chain for aircraft design. This paper introduces a novel feature of this process chain, implemented in the Python tool called “Parametric Numerical Design and Optimization Routines for Aircraft” (PANDORA) developed at the Institute of Structures and Design (BT) featuring enhanced numerical tools for the fuselage structure analysis and sizing. The ongoing development focuses on achieving a high level of detail in the aircraft Finite Element (FE) modeling chain for crashworthiness evaluations, including a more detailed cabin description as well as advanced anthropomorphic test devices (ATDs). The aim is to study the dynamic behavior of novel cabin layouts and structures under crash conditions starting from their parametrical definition, and evaluate innovative design choices in terms of safety. Such a fully integrated process chain becomes necessary due to recent changes in aviation crashworthiness regulations, where the shift from prescriptive to performance-based requirements may significantly influence both the aircraft design and certification process.
