Abstract

The goal of this paper is to illustrate how advanced numerical techniques can be combined to perform optimal design for complex aerospace geometries. With the advent of parallel computers and efficient multigrid flow solvers using unstructured meshes, full 3D computations can be performed in minutes rather than days. It is thus possible to evaluate derivatives of key design variables (such as wing thickness or camber) and utilise these within an optimisation procedure to improve upon an initial design. In this paper such a method is used for a particular design application, the re-design of a row of outlet guide vanes in the bypass duct of a turbofan aero-engine.
