摘要
为提升多旋翼无人机抗风性能,对倾斜式双旋翼的气动特性进行分析。通过分析桨盘倾角对同轴非共轴形式布局的影响,螺旋桨与电机座之间采用一定安装角倾斜安装,以增大偏航控制力矩,倾斜式的桨盘设计使每个旋翼具备多个旋转自由度,能够有效地纠正姿态,提高无人机的稳态性能。对不同倾角的双旋翼进行了试验和计算流体力学(computational fluid dynamics,CFD)数值模拟。结果表明:该研究能为倾斜式多旋翼无人机提供设计支撑。
In order to improve the anti-wind performance of multi-rotor UAV,the aerodynamic characteristics of tilt-rotor were analyzed.By analyzing the influence of the rotor disk inclination angle on the coaxial and non-coaxial configuration of the UAV,a certain installation angle is adopted between the propeller and the motor base to increase the yaw control moment,and the inclined rotor disk design enables each rotor to have multiple rotational degrees of freedom,which can effectively correct the attitude and improve the steady-state performance of the UAV.Experiments and computational fluid dynamics(CFD)numerical simulations were carried out on twin rotors with different pitch angles.The results show that the research can provide design support for the tilting multi-rotor UAV.
