Wing Optimization Design Based on Composite Global Hawk Unmanned Aerial Vehicle

Abstract Composite materials have become the approach to solve high stiffness and light weight of unmanned aerial vehicle structures. The wing had an extremely important influence on flight vehicle. optimal composite design aroused widespread attention since it enhanced aerodynamic performance vehicles. This article was intended optimize with advantages in performance. According parameters military-civilian integrated vehicle, a three-dimensional model overall structure Global Hawk designed. effect optimization laminate layup were studied. XFLR5 software utilized analyze wing. original NACA0012 airfoil optimized NACA3412 analyzed respectively for conduct simulation under set parameters, changing angle attack analyzed. results demonstrated that outperformed terms lift, drag, torque, lift-drag ratio.
