摘要
采用粒子图像测速(PIV)技术,对悬停状态下直升机旋翼尾迹进行了全面测量,获得了在不同试验条件时旋翼流场的涡量和速度分布。测量结果合理可信,为开展旋翼流动机理研究及提高CFD分析精度奠定了基础。
Using Particle Image Velocimetry （PIV） technique, the full-scale measurements of wake geometry for helicopter rotors in hover were conducted. Vortex contours and velocity distribution of the rotor flow fields in different conditions were obtained. The results of measurements were reasonable and believable. It laid the foundations of the rotor flow principium investigation and improving CFD analysis precision.
