AERONAUTIC APPLICATIONS

Abstract. This paper shows how the optimisation environment modeFRONTIER is applied to solve multi objective problems in aeronautic field. These problems include solution robustness on uncertain definition of parameters, and automatic and distributed communication between parametric CAD and simulation software. Two application cases are presented: first, a 3D wing defined and parameterised in CATIA V5, is to be optimised for two different mission points, clean wing in cruise transonic regime and opened high-lift devices for subsonic take-off, following aerodynamic criteria and constraints. Second, the shape of a transonic airfoil is to be optimised under uncertainties of flight conditions, in order to optimise not only the design point, but to keep efficiency as well after operating condition fluctuations
