| 摘 要： | 采用PIV（粒子图像测速）技术，对共轴式双旋翼在悬停和以不同速度前飞时的流场进行水洞试验，测量得到旋翼流场的速度和涡量分布，主要研究了共轴式双旋翼流场的垂向诱导速度沿径向的分布规律。为了比较，对单旋翼也进行了测量。试验结果对共轴式直升机的气动计算和合理设计具有重要意义。

| Abstract: | Particle Image Velocimetry technique is applied to the experiment of coaxial-rotor in hover and in level flight in water tunnel.Velocity vectors and vortex contours of the rotor flow fields are measured.The radial distribution of vertical induced velocity of coaxial-rotor flow fields is mainly investigated.For comparison,single-rotor is also measured.The experimental results have important meaning to the aerodynamic calculation and reasonable design of coaxial-rotor helicopter. |
