Implementation of a heterogeneous, variable-fidelity framework for flight mechanics analysis in preliminary aircraft design
2011
This paper presents the implementation of a framework for flight mechanical analysis with adaptable
aerodynamics methods in the preliminary stage of aircraft design. Basis to the framework are software
modules for the disciplines conceptual design, flight mechanics and aerodynamics which have been
developed within different design frameworks and which contain heterogeneous interfaces. The focus is
placed on the technique for the integration of the different analysis components and the realization of the
variable-fidelity capability. Backbone of the framework is the XML-based 'Common Parametric Aircraft
Configuration Schema' (CPACS) which was extended in course of this study. The paper introduces the
utilized analysis codes and software modules, presents their integration into the framework and discusses
the faced challenges and developed solutions. Exemplary results are shown as illustrative use cases.
Analogies of linked design systems lead to a standardized integration process. In a next step the
homogenization of different design systems by a unified parameterization appears to be feasible.
