Original abstract

We are using test cases proposed by the AIAA Discussion Group on Aerodynamic Design Optimization in order to compare two different approaches of parameterization. The methods are a Free-Form Deformation (FFD) scheme under development and a Radial Basis Function (RBF) approach. The main criteria we are observing are convergence behavior, e.g. when increasing the number of design parameters, and ability to resolve geometric constraints. Results for the NACA0012 airfoil and the RAE2822 airfoil test cases are presented, as well as a preliminary study of wing shape optimization.

Czech abstract

Za účelem porovnání dvou různých přístupů tvarové parametrizace byly použity testovací úlohy navržené AIAA Discussion Group on Aerodynamic Design Optimization. Paremetrizační metody zkoumané v publikaci jsou momentálně vyvýjena metoda Free-Form Deformation (FFD) a Radial Basis Function (RBF). Hlavní zkoumaná kritéria jsou chování konvergence, tj. vliv zvyšování počtu návrhových proměnných, a schopnost dodržení geometrických omezení. Jsou zde prezentovány výsledky tvarové optimalizace profilů NACA0012 a RAE2822, dále předběžné výsledky tvarové optimalizace křídla.
