用三维激光多谱勒测速仪对共轴双旋翼悬停流场的测定
MEASUREMENT OF THE COAXIALROTOR FLOWFIELDIN HOVERING USING 3D LASER DOPPLER VELOCIMETER
【摘要】 用三维激光多谱勒测速仪对共轴式双旋翼在悬停状态的流场进行了实验测量。测量了各测试点诱导速度沿三个方向(轴向、径向和周向)的分量,得到了两旋翼尾迹交汇、干扰下的流场直观图像和重要信息。为了对比,对单旋翼流场也进行了测试,并给出了二者之间的差别。
【Abstract】 This paper describes the measurement of a coaxialrotor flowfield in hovering using a 3D Laser Doppler Velocimeter.Three components of the induced velocity along axial,radial and circumferential direction and intuitive figure of the flowfield are shown.For purposes of comparison,the measurement of singlerotor flowfield in hovering was conducted and the differences between the single and the coaxial rotors are presented here.
