| 摘 要： | 无人多旋翼飞行器使用的桨叶以固定翼螺旋桨为主,但其气动环境与固定翼不尽相同。使用逆向重构技术对原始桨叶进行参数化建模,并基于CFD数值计算技术对参数化基准模型的扭转角分布规律和叶型积叠方式在垂直飞行状态下进行优化设计。结果表明:在功率允许范围内,桨叶在悬停状态下的效率有了较大提升。

| Abstract: | In this paper, the methods of reverse reconstruction and parametric modeling of the propeller are mainly studied. The torsion angle distribution and the pattern of the leaf-type stacking of the existing propeller model are optimized. In this paper, the propeller is taken as an example, and its reconstruction and parametric modeling are carried out. Numerical calculation techniques based on high-precision algorithms such as structured rotating grid and N-S equation are established and tested by experiments. Based on this, the CFD calculation of the propeller, the analysis and optimization of the blade twist angle and the stacking method are carried out to provide the help of the existing blade pull-down power |
