This study proposes a design procedure for the multi-objective aeroelastic optimization of tow-steered composite wing structure that operates at transonic speed. The aerodynamic influence coefficient matrix is generated using doublet lattice method, with steady-state component further refined through high-fidelity computational fluid dynamics (CFD) analysis to enhance accuracy in conditions. Finite element (FEA) used perform structural analysis. A problem formulated structure, where objective functions are designed mass and critical speed, constraints include limits. comparative eight state-of-the-art algorithms conducted evaluate their performance solving this problem. Among them, Multi-Objective Multi-Verse Optimization (MOMVO) algorithm stands out, demonstrating superior achieving best results task.
