The invention relates to the technical field of helicopter rotor detection. The invention provides a helicopter rotor common taper detection method and device. The method comprises the following steps: acquiring a first detection signal and a second detection signal which are correspondingly output by the same blade of the helicopter after the same blade passes through two different photoelectric detectors in sequence, and determining the time required by the blade to pass through a detection area formed by the two different photoelectric detectors according to the first detection signal and the second detection signal, and determining the relative height difference of all the adjacent blades of the helicopter according to the required time, and determining the common taper of the helicopter rotor according to the relative height difference of all the adjacent blades. According to the method provided by the invention, the error of the measurement result is reduced, and the measurement precision is improved.

    本发明涉及直升机旋翼检测技术领域。本发明提供一种直升机旋翼共锥度检测方法与装置。该方法包括:获取直升机的同一片桨叶先后经过两个不同光电探测器后,其对应输出的第一探测信号和第二探测信号,根据第一探测信号和第二探测信号,确定该片桨叶经过由两个不同光电探测器构成的探测区域所需时间,根据所需时间确定该架直升机所有相邻桨叶的相对高度差,根据所有相邻桨叶的相对高度差确定直升机旋翼的共锥度。本发明提供的方法,减少了测量结果的误差,提高了测量精度。
