摘　　要：针对直升机桨叶扭转角测量方法进行了深入研究,包括技术背景、传统测量方法介绍、测量方法改进和试验结果分析等;提出了基于数字图像相关法的直升机桨叶扭转角测量方法,克服了传统激光三角法无法精确跟踪桨叶测量剖面上变形前后同一点的位移等各种弊端。This paper aimed at the further research on measurement method of helicopter blade torsional angle,including technical background,traditional measurement methods and improvement,analysis of test results and so on.Proposed measurement method for helicopter blade torsion angle which based digital image correlation method.It Overcame the disadvantages that the traditional laser triangulation method could not accurately track the displacement of the same point before and after the deformation on the blade measurement section.
