Abstract

This paper introduces a tool chain for extended physics-based wing mass estimation. Compared to state-of-the-art tool chains, the physics-based structural modeling is extended beyond the wing primary structure. The structural model also includes the movable trailing edge devices incl. tracks, spoilers, engine pylons and the landing gear. The chain includes the structural analysis model, models for aerodynamic, fuel, landing gear and engine loads as well as a sizing algorithm. To make the complexity of the model generation process feasible for preliminary aircraft design, a knowledge based approach is chosen. This means, that the analysis models are created partly automatic, which leads to a minimum set of required input parameter for the central model generator. The DLR aircraft parameterization format CPACS (Common Parametric Aircraft Configuration Scheme) is used as central data model for input and output. Therefore the chain can be easily included in a wider multidisciplinary aircraft design environment.
