1　引言旋翼共锥度的测量 ,是直升机生产、维护中的重要检查项目。但由于共锥度的测量是在旋翼高速旋转的动态下进行 ,所以在过去一直存在着测量难度较大、测量精度较差的问题。随着光电技术、电子技术 ,特别是信息技术的发展 ,使得对旋翼共锥度的测量现在已能做到用多种测量方 1 Introduction Rotor total taper measurement is an important inspection item in helicopter production and maintenance. However, since the measurement of common taper is carried out under the dynamic rotation of the rotor at high speed, there has always been a problem that the measurement is difficult and the measurement accuracy is poor in the past. With the development of optoelectronic technology, electronic technology, especially information technology, the measurement of the total conicity of the rotor can now be achieved with a variety of measuring parties
