The invention generally belongs to the field of aircrafts, and provides a dynamic deflection measuring device for a high-speed rotor. The dynamic deflection measuring device comprises a beacon device (1), a near scale (2) and a far scale (3); the beacon device (1) is embedded in a blade (61) of the rotor system (6) and is located at a measuring point (611) where deflection measurement needs to be carried out; the near scale (2) and the far scale (3) are common rulers, and the length of the near scale (2) and the far scale (3) exceeds the sum of the radius of the rotor system (6) and the distance from the far scale (3) to the rotor system (6); and the near scale (2) and the far scale (3) are fixed at positions parallel to a rotor disc plane of the rotor system (6), and the distance from the far scale (3) to the rotor system (6) is greater than the distance from the near scale (2) to the rotor system (6). The device is used for rotor wing ground test and can also be used for dynamic deflection measurement of wind driven generator blades.
本普通发明属于飞行器领域。提供一种高速旋翼动态挠度测量装置,包括:信标装置(1)、近处标尺(2)和远处标尺(3);信标装置(1)镶嵌在旋翼系统(6)的桨叶(61)内部,位于需要进行扰度测量的测量点(611)处;近处标尺(2)、远处标尺(3)为普通直尺,长度超过旋翼系统(6)的半径与远处标尺(3)至旋翼系统(6)的距离之和;近处标尺(2)、远处标尺(3)固定在于旋翼系统(6)的桨盘平面平行的位置,远处标尺(3)至旋翼系统(6)的距离大于近处标尺(2)至旋翼系统(6)的距离。本发明用于旋翼地面试验测试,也可用于风力发电机叶片动态挠度测量。
