结合"太阳神"无人机(UAV)和高山兀鹫提出了太阳能UAV的某仿生全翼式构型,针对该构型开展了气动分层协同设计及分析。在设计和分析过程中,自下而上将设计分为三个层次,基于纵向配平需要以低雷诺数反弯内翼翼型设计为第一设计层次,基于高升力需求以外翼设计为第二设计层次,以UAV全机性能设计为第三设计层次;与此同时,每个层次均采用基于代理模型的基本优化流程,三个层次的设计自上而下来相互协同,最终得到满足指标的设计结果。研究结果表明:分层协同设计提高了设计效率,获得了高效的仿生全翼式太阳能UAV构型;证明了设计方法的可行性和设计结果的有效性。

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.
