【摘要】：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。
[Abstract]:With the "Sun God" UAV (UAV) and Gyps himalayensis is proposed for a bionic solar UAV full wing configuration, the configuration of the aerodynamic design and analysis of hierarchical collaborative. In the design and analysis process, bottom-up design is divided into three levels, need to longitudinal trim low Reynolds number contraflexure inner wing airfoil design is the first design level based on high lift wing based on demand to design second design level, to UAV the performance of the whole machine design third design level; at the same time, each use the basic level of process optimization based on surrogate model, top-down design three levels to cooperate, finally get the results meet the design index. The research results show that the hierarchical collaborative design improves the design efficiency and obtains an efficient bionic full wing solar UAV configuration, which proves the feasibility of the design method and the effectiveness of the design results.
