The interference effect between the nano rotor and aerodynamic rudder was studied experimentally and computationally. Propulsive performance of nano rotor and aerodynamic performance of aerodynamic rudder were achieved experimentally. The disturbed flow field of nano rotor was also analyzed computationally to disclose the flow mechanics of the interaction. Results showed that the nano rotor has a great effect on the aerodynamic performance of aerodynamic rudder. The moment of aerodynamic rudder fluctuated with the rotor-to-rudder spacing and achieved the smallest value at the spacing of 0.5R. And the moment of aerodynamic rudder varied with deflection angle linearly. Aerodynamic rudder influenced the propulsion performance of the nano rotor slightly. The thrust coefficient and torque coefficient increased a little with spacing but changed slightly with the deflection angle. Numerical simulation showed that aerodynamic rudder blocked the flow field of the nano rotor and the counterclockwise rotation of the rotor drives the flow in the downstream rotating in a counterclockwise direction resulting in the different angle of attack between left and right rudder surface.

纳米转子与气动舵相互作用的实验与计算研究

通过实验和计算研究了纳米转子与气动舵之间的干涉效应。通过实验实现了纳米转子的推进性能和气动舵的气动性能。还通过计算分析了纳米转子的扰动流场，以揭示相互作用的流动力学。结果表明，纳米转子对气动舵的气动性能有很大影响。气动舵的力矩随旋翼到舵的间距而波动，在0.5R的间距处达到最小值。气动舵的力矩随偏转角呈线性变化。气动舵对纳米转子的推进性能有轻微影响。推力系数和扭矩系数随间距增加略有增加，随偏转角略有变化。数值模拟表明，气动舵阻挡了纳米转子的流场，转子的逆时针旋转带动下游流动逆时针旋转，导致左右舵面迎角不同。
