Measurement Method of Helicopter Blade Torsion Angle
This paper aimed at the further research on measurement method of helicopter blade tor-sional angle,including technical background,traditional measurement methods and improvement,a-nalysis 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 la-ser triangulation method could not accurately track the displacement of the same point before and af-ter the deformation on the blade measurement section.
