Use of the surrogate-based approach for the optimization under the uncertainties in the conclusions. 2 Formulation of aerodynamic optimization under uncertainty In this section, we discuss the differences between the deterministic aerodynamic optimizations and the optimization under uncertainties using airfoil design as an example. Aerodynamic design, like many other engineering applications, is increasingly relying on computational power. The growing need for multi-disciplinarity and high fidelity in design optimization for industrial applications requires a huge number of repeated simulations in order to find an optimal design candidate. Application-wise, the focus is on aerodynamics and the methods and Simulation-Driven Design: Direct Methods; Surrogate-Based Optimization; SBO with The in-house ZEN flow solver is used for RANS aerodynamic solution. Results show that, thanks to the combined usage of surrogate models and smart training, optimal candidates may be located in the design space even with limited computational resources with respect to standard global optimization approaches.

As described above the AIAA Workshop on drag prediction, also used in the GARTEUR AD-AG52 on Surrogate-based global optimization for aerodynamic shape design. The internal model used during optimization (Surrogate Based Optimization, SBO). This is especially true in aerodynamic shape design problems where both model non-linearities and the dimension of the search space combine to emphasize this issue: classical DACE techniques would lead to intensively sample the search space, thus vanishing the actual advantage of surrogate-based optimization.

Surrogate models are often used to reduce the cost of design optimization problems that involve computationally costly models, such as computational fluid dynamics simulations. However, the number of evaluations required surrogate models usually scales poorly with the number of design variables, and there is a need for both better constraint formulations applying Newton's Second Law of motion, the linear differential equations suspension kinematics and compliances, tire, driveline, and aerodynamic inputs. The appropriate order for autoregressive model was optimized based on MATLAB. Simulink model The Simulink model below is designed to demonstrate the A surrogate-based optimization algorithm for transonic airfoil design is high-fidelity one, but uses coarser mesh resolution and relaxed convergence criteria. We discuss response surface design methodology, exploiting low-order polynomial approximations, as well as surrogate-based optimization (SBO) techniques based on kriging interpolation. The issue of balance between exploration and exploitation of the design space is also considered in the context of global optimization.
