Automated Structural Sizing in Early Aircraft Design with Python
summary
A Python-based design chain at DLR builds an open, modular pre-design tool for aircraft fuselage structural layout, including an FE preprocessor and FE converter with a CPACS XML interface. It uses Pandas and object-oriented model classes to generate geometry, variable meshing and exports to FE formats, supports visualization and an interactive skin-thickness sizing tool on Windows, handles datasets up to 150,000 rows, and runs faster and more flexibly than older PDL scripts as a functional prototype in development.
