Trailing edges (Aerodynamics), Wing-warping (Aerodynamics)


This research aims to investigate parameterization and optimization methods to attain an optimum trailing edge (TE) deformation tailored to different aerodynamic objective functions (C(subscript l), C(subscript l)/C(subscript d), C(subscript l)³/C(subscript d)²). Discontinuous Modified Class/Shape Transformation (dMCST) is used to create the design parameters for the tE curvature. Gradient free optimization methods (sequential model-based, population-based) are tested to obtain a globally optimized design. Subsequently, surrogate-based computational models are trained and aim to replace high-fidelity CFD solvers, such as ANSYS Fluent, to expedite the optimization process. To verify the veracity of these models, a comparison between Xfoil and the trained best surrogate model result is conducted using the best population-based optimization method. Results indicate that dMCST as parameterization and sequential model-based optimization, with the variability of surrogate functions (Gaussian process for C(subscript l), C(subscript l)/C(subscript d), and Extra trees for C(subscript l)³/C(subscript d)², is found to be optimization method to attain the global optimum design for the wing’s TE deflection.
