A Code for Shape Generation and Aerodynamic Design of Aircraft
Multidisciplinary preliminary optimization of aircraft requires an integrated framework, where different modules are capable to interact with each other. The code presented in this paper is a platform where shape modeling, grid generation, and aerodynamic configuration evaluation are integrated. In the geometric modeling module the aerodynamic configuration is defined, and the process of shape definition is easily achieved with the aid of specific features. In this optic, useful tools like section sketcher, airfoil manager, NACA airfoil generator, and flap sketcher are also available. Once the reference parameters are set, a NURBS description is given. In the meshing module structured or unstructured grids are built on the defined configuration. The structured grid is exported according to the most popular standards, in order to use it as input grid for panel method codes integrated within the aerodynamic module to carry out the aerodynamic configuration evaluation. The unstructured grid can be exported in different standard in order to eventually submit more accurate and time-consuming aerodynamic analysis by means of external CFD programs.
Thanks to Andrea Rimondi and Fabrizio Petri for their efforts in writing most of the geometric module features. Thanks to Giovanni Bernardini, Roma 3 University, for his contribution and suggestions on panel method theory and practice.
