摘要

为了研究螺旋桨与弹载无人机的相互干扰,使用滑移动网格技术对螺旋桨进行数值仿真,借助颗粒轨迹、分段受力计算和相关力矩计算对仿真结果进行分析。分析结果表明螺旋桨的干扰会对无人机稳定性产生影响,借助副翼偏转和垂尾的恢复力矩可以使无人机保持相对稳定;螺旋桨的滑流掠过机翼使升力增加,并产生与螺旋桨扭矩相反的力矩。

Abstract

The slide mesh technology has been used for the objective that the interference between propeller and UAV is researched through numerical simulation. In the process of analyse, the method of the particle track, part of force and statistic of moment has been done. The result shows that UAV can keep relatively stable by aileron and vertical tail. The propeller slipstream has some effect to UAV, such as the increase of life in the wing and reversed torque of propeller.

Key words： propeller; UAV; airflow interference; dynamic mesh
