Robust Algorithm Software for NACA 4-Digit Airfoil Shape Optimization Using the Adjoint Method

open access: yesApplied Sciences, 2023
Optimizing the aerodynamic shape of an airfoil is a critical concern in the aviation industry. The introduction of flexible airfoils has allowed the shape of the airfoil to vary, depending on the flight conditions. Therefore, in this study, we propose an

Improving the Gridshells’ Regularity by Using Evolutionary Techniques

open access: yesMathematics, 2021
Designing and optimizing gridshell structures have been very attractive problems in the last decades. In this work, two indexes are introduced as “length ratio” and “shape ratio” to measure the regularity of a gridshell and are compared to the existing ...
