Fluid-Structure Interaction and Design Optimization of HAR wing for Endurance efficiency of S-HALE aircraft

摘要

In this paper, S-HALE aircraft wing sizing optimization is conducted at 20km altitude by modifying 3 variables including span length, aspect ratio and weight distribution along the spanwise direction of the wing for 24-hour continuous flight. Fluid-Structural Interaction is conducted for static stability of wing and high estimation of aerodynamic performance. 3-dimensional Euler equation and MSC.Nastran are used for aerodynamic and structural analysis. Finally we check the energy flow of S-HALE during a day and confirme that the S-HALE can fly 24-hour continuously.
