摘 要:随着目前国内新概念布局的快速发展及新技术验证的急迫需求,拥有低成本及无人化等优势的缩比无人机越来越多地被用作技术验证机及高性能靶机。本文通过对若干型高性能缩比无人机翼载、推重比及缩放比例这三项最关键的总体参数进行对比分析,发现了缩比无人机与原准机在翼载参数上存在根本性差异,并由此导致缩比无人机性能与原准机的巨大差异。经过大量数据统计分析,确定缩比无人机与原准机总体参数差异的根本原因。通过若干经验公式,针对翼载差异对飞行、机动、巡航、起降及隐身等总体性能方面可能造成的影响进行了定性分析,并针对不同功能及任务需求的缩比无人机提出相关总体设计建议。With the rapid development of the domestic new concepts of layout and the urgent need for verification of new technology currently,scaled target drones with low cost and unmanned capabilities are increasingly being used as technology verification machines and high-performance target drones.Through the comparative analysis of the three most critical population parameters of several high-performance scaled UAVs:wing load,thrust-to-weight ratio and zoom ratio,it is found that the fundamental differences of wing load parameters are existed between the scaled UAV and the original quasi-machine.Through a large amount of statistical analysis of data,the root cause of the population parameters difference between the scaled UAV and the original quasi-machine is determined.By using a number of formulas,this paper makes a qualitative analysis on the influence of the wing load differences on the population performance of flight,maneuvering,cruise,take-off,landing and stealth,etc.,and gives some suggestions on the total design of the scaled UAV with different functions and mission requirements.
