摘　　要：为探讨后置螺旋桨对双尾撑无人机的干扰情况,采用非结构网格模型,并使用k-ωSST湍流模型和旋转坐标系进行气动数值模拟。计算结果表明,由于螺旋桨滑流影响了平尾流场,导致双尾撑无人机阻力系数增加,螺旋桨距前机身越近,阻力系数增加越明显;由于双尾撑无人机前机身对螺旋桨起到了遮蔽作用,螺旋桨的推力和扭矩明显增大。螺旋桨距离前机身越近,推力和扭矩增大越明显。To investigate the aerodynamic interference between mounted propeller and twin-tailboom UAV,the unstructured grid model,k-ωSST turbulence model and rotating coordinate system were used to simulate the aerodynamic characteristics of the UAV model with mounted propeller.The results indicate that the drag coefficient of the twin-tailboom UAV increases under the influence of the propeller because the propeller slipstream affects the flow field of the horizontal tail,and the closer the propeller is to the front fuselage,the more the drag coefficient increases.The thrust force and torque of propeller increase obviously under the influence of the twin-tailboom UAV because the propeller is shielded by the front fuselage,the closer the propeller is to the front fuselage,and the more the thrust force and torque of the propeller increase.
