The document presents a novel two-level free-form deformation (FFD) framework for high-fidelity aerodynamic shape optimization (ASO). This approach utilizes non-uniform rational B-splines to maintain an analytical representation of geometry during deformation, facilitating efficient mesh movement. The methodology is demonstrated by optimizing the lift-to-drag ratio of a half-sphere-shaped geometry using a gradient-based optimizer and an Euler-based flow solver. The paper discusses the advantages of CAD-free systems over traditional CAD-based methods, emphasizing flexibility in shape parameterization and integration with structural analysis. Results indicate the effectiveness of the proposed framework in achieving robust aerodynamic designs.
