研究了开式旋翼推进装置中后旋翼对旋翼间流场的影响。相位锁定到前转子位置的粒子图像测速（PIV）数据集已根据前转子和后转子之间的相对相位角进行相位平均。通过图像处理算法对原始PIV图像进行特征跟踪，确定后旋翼相位。分析了后旋翼势场对旋翼间流场的影响，并与计算流体动力学（CFD）模拟结果进行了比较。结果表明，后旋翼对前旋翼桨尖涡的位置没有实质性影响，但当旋翼高载荷时，对涡的环量强度有很小的影响。
The effects of the aft rotor on the inter-rotor flow field of an open rotor propulsion rig were examined. A Particle Image Velocimetry (PIV) dataset that was acquired phase locked to the front rotor position has been phase averaged based on the relative phase angle between the forward and aft rotors. The aft rotor phase was determined by feature tracking in raw PIV images through an image processing algorithm. The effect of the aft rotor potential field on the inter-rotor flow were analyzed and shown to be in good agreement with Computational Fluid Dynamics (CFD) simulations. It was shown that the aft rotor had no substantial effect on the position of the forward rotor tip vortex but did have a small effect on the circulation strength of the vortex when the rotors were highly loaded.
