Linkage Learning Optimization of Aeroelastic and Structural Behavior of Composite Wings
Roham Rafiee,Touraj Farsadi,Majid Ahmadi Tehrani,Parsa Sharifi 한국항공우주학회 2023 International Journal of Aeronautical and Space Sc Vol.24 No.5
The paper aims to develop a systematic numerical design for composite wings optimization subject to aerodynamic loading and to assess the aeroelastic and structural performance of the optimized composite wing. Aeroelastic tailoring is a powerful method for utilizing the anisotropic features of composite materials used in lightweight aerospace structures. The present proposed methodology combines three different analysis tools: a commercial FE software commonly used in industry, an in-house reduced order aeroelastic framework for aeroelastic analyses with tailoring capabilities, LLGA, in-house linkage-learning genetic algorithms for optimization of stacking sequences. As a multidisciplinary problem where structural and aeroelastic behaviors are interacted, developed multi-level optimization scenario in this research converges to the optimal design in a very short time. The proposed methodology implemented as a computer code can effectively be applied to any arbitrary air vehicle’s composite wing by changing input data.
