Multilevel collaboration design and analysis of bionic full-wing typical solar-powered unmanned aerial vehicle

Based on “Helios” unmanned aerial vehicle (UAV) and Himalayan Vulture, a bionic full-wing typical solar-powered UAV configuration is determined. Aerodynamic multilevel collaboration design and analysis is carried out for the configuration. In the process of design and analysis, design is divided into three levels with bottom-up ideas. The first level is anti-camber low Reynolds airfoil design of inner wing to meet pitching-moment balance. The second level is outboard wing design to gain high lift. Full UAV performance design is used as the third design level. At the same time, each level uses basic optimization press based on surrogate model. Three design levels collaborate by top-down to gain design result which satisfies design index. The results show that aerodynamic multilevel collaboration design improves the design efficiency to get the excellent configuration of bionic full-wing typical solar-powered UAV and proves the feasibility of design method and the effectiveness of design result.
