飞翼布局无人机实验平台设计与实现
|
摘要
探索了飞翼布局无人机的设计思路,完成了2种设计方案,利用CFD方法获得了该飞机基本气动数据,建立了方案B的CATIA三维数字样机,实现了实验平台的制作、装配和测试工作,基于该实验平台开展了一系列飞行实验。CFD计算结果和试飞数据验证了设计方法的可行性,体现了实验平台的通用性及良好的工程应用前景。
The design idea of UAV(unmanned aerial vehicle) with flying wing configuration is explored and two design schemes are completed. The basic aerodynamic data of the aircraft are obtained by the CFD(computational fluid dynamics) method, and the CATIA 3 D digital prototype of the scheme B is established. The fabrication, assembly and testing of the experimental platform are realized. Based on this experimental platform, a series of flight experiments are carried out, and CFD calculation results and flight test data validate the feasibility of the design method, which reflects the versatility of the experimental platform and good engineering application prospect.
