涵道式飞行汽车新型结构的气动性能数值模拟

摘要

With the analysis of the advantages and limitations of the foreign and domestic flying car,a new type ducted flying car structure with greater regional adaptability is proposed,which is combined with the characteristics of helicopter's large lift,medium endurance and multi-rotor aircraft's high precision control.The design process includes goal setting,plan list,theoretical analysis and so on.Compared with two existing structures,the structure and aerodynamic performance characteristics of the new type ducted flying car are discussed.By numerical simulation,it comes to the conclusion that the new structure is worthy of further research and development.%在研究国内外飞行汽车优势与局限性的前提下,结合共轴反转双旋翼直升机升力大、续航中等以及多旋翼飞行器控制精度高的特点,通过目标设定、方案罗列、理论分析等步骤,提出一种区域适应性更强的涵道式飞行汽车新结构.与两种现有飞行汽车结构进行对比,探讨涵道式飞行汽车的结构及气动性能特点.气动性能数值模拟结果表明该飞行汽车结构值得继续研发与尝试.
