Assessment of Inverse and Direct Methods for Airfoil and Wing Design
2016 (English)In: SIMULATION-DRIVEN MODELING AND OPTIMIZATION, 2016, 75-109 p.Conference paper (Refereed)Text
Abstract [en]

The goal of aerodynamic design for airfoils and wings is to improve the performance of the lifting surfaces, e.g., by minimizing the drag. We consider here two approaches, the classical inverse design approach that finds the surface which produces desired pressure distributions, and the direct mathematical optimization based on local parameter searches, that is usually enabled by fast gradient computation, for example, by the adjoint method. The hybrid approach is to combine both of them. Each approach has its own pros and cons. In this chapter the approaches are assessed by application to the design of transonic RAE2822 airfoil and ONERA M6 wing.
