基于光电技术的直升机旋翼同锥度检测装置

摘要

Under the detailed analysis of the helicopter rotor same taper detection on the basic current situation home and abroad,considering the helicopter in hovering ground mooring,ground effect,no effect hover and low speed flight state near the rotor with demand taper detection,by using a laser beam of CCD linear array and sensitization to original position to distinguish rotor with taper,gave the hardware block diagram and calculation method.%详细分析了直升机旋翼同锥度检测在国内外的发展现状，综合考虑了直升机在地面系留、有地效悬停、无地效悬停和低速近距离前飞等状态的旋翼同锥度检测需求，利用激光束直接照射 CCD 线阵，采用感光像元位置区分旋翼同锥度，并给出了硬件框图和计算方法。
