Abstract:

This paper focuses on aerodynamic design methodology. It discusses challenges and complexity of aerodynamic wing design for a transonic aircraft, which arise from the complex nature of flow around the wing. It introduces the concept of automatic design based on computational fluid dynamics (CFD) and the concept of adjoint method. At the conceptual level, the adjoint method largely simplifies the complexity of the design, yet makes the optimization process possible at the practical level. A redesign for a shock-free wing is presented, showing the effectiveness of the automatic design. An extension to include a large scale wing design such as planform optimization is also presented. However, a new cost function needs to be properly chosen and the problem actually leads to multi-objective optimization. Successful planform design results also confirm the robustness of this automatic design strategy.
