针对现有微小型无人飞行器气动设计问题,提出了一种能有效改善微小型无人飞行器机动性能的气动优化设计方案,完成了气动外形的三维建模,得到了亚声速条件下的气动特性,得出了平原条件下最大可用过载为3.2 g,高原(4 500 m)条件下最大可用过载为1.7 g。结果表明,所提出的微小型无人飞行器具有良好的机动性能,实现了气动优化设计的目的。
Aiming at the aerodynamic design problem of existing micro UAV, a aerodynamic optimization design scheme that can effectively improve the maneuverability of the UAV is proposed. The aerodynamic characteristics of the UAV are achieved by three-dimensional modeling of the aerodynamic profile , The maximum available overload under plain conditions is 3.2 g and the maximum available overload under plateau conditions (4 500 m) is 1.7 g. The results show that the proposed micro UAV has good maneuverability and achieved the purpose of aerodynamic optimization design.
