| Abstract | INTRODUCTION To achieve optimal overall performance of a transport aircraft over its complete mission, the aerodynamic design of its wing must consider the variations of operating conditions the aircraft will encountered. During the cruise segment, such variations have several origins: cruise speed variations motivated by operational reasons (imposed arrival time by the ATM), variation of the aircraft weight as the fuel is burnt along the mission, intentional cruise altitude changes. To account for this variability of the operating cruise condition and optimize the aircraft accordingly, a natural approach consists in performing a multi-point optimization of the aerodynamic performance. This consists in solving an optimization problem which objective function is for example a linear combination of the aerodynamic performances at several flight conditions. In this work, it is proposed through applications considering a modern civil aircraft wing, to highlight the advantages of multipoint flexible wing optimization in comparison to single point rigid optimizations. |
