Coupled CFD-based Shape Optimization of a Wing of Reusable Space Vehicle of Tourist Class

This article proposes an approach to two-stage shape optimization of the wing of tourist class reusable space vehicle. To achieve appropriate lift and drag force levels, CFD-based optimization methods in combination with geometric parametrisation was applied. During the first stage, the optimization focuses on reduction of wing square and providing required velocity during vehicle’s landing. In this case, for improving the aerodynamic and mass characteristics five geometric design variables were used. The second stage of optimization emphasis on drag force minimization in order to enhance the wing shape in assigned design area by means of adjoint discrete method.
