直升机旋翼共锥度测量系统的设计与实现

Design and realization of helicopter blade running elevation measurement system

直升机旋翼的共锥度是影响直升机机动性能方面很重要的指标,针对过去对直升机旋翼共锥度的测量存在的测量难度大、精度差等一系列问题,主要介绍了利用光电技术构建的直升机旋翼共锥度测量系统的设计与实现,并对共锥度测量的原理和测量系统的设计及精度分析做了详细的讨论.最后对此测量系统进行了模拟试验,得到的共锥度测量数据误差很小,并且系统很稳定,证实了此测量系统的可行性.

Proper helicopter blade running elevation is important. However, it is difficult to obtain a precise measurement of the blade running elevation. A new system using photo electricity technology was designed. Analysis of simulation experiments shows that the method produced very small measurement error and that the method is feasible.
