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。The propeller blades used in unmanned multi-rotor aircraft are mainly fixed-wing propellers,but their aerodynamic environments are not the same.The parametric modeling of the original blades is established by using the inverse reconfiguration technique and based on CFD technology the design of the parametric reference model’s torsional angle distribution and the leaf-type stacking pattern in the vertical flight state is optimized.The results show that the efficiency of the blade in the hovering state is greatly improved within the power allowable range.
