飞行中螺旋桨相位测量技术

在螺旋桨桨轴1P载荷飞行测量中,利用激光传感器完成了螺旋桨相位测量。结合相位信号和桨轴载荷受力分析计算,实现了飞机爬升状态下桨轴1P载荷的分离计算。飞行试验中获得的螺旋桨相位信号清晰稳定,表明测试方法是成功的,为桨轴载荷的分析计算提供了关键参数,较好的解决了螺旋桨1P载荷桨轴直接测量中的相位问题。

Technology of Inflight Propeller Phase Measurement

A Laser sensor was used to measure propeller phase during aero-engine power shaft load inflight test. The 1P load of the shaft was analyzed using measured propeller phase and the load state. That the propeller phase signal measured in flight test was legible and stable indicated the measurement was successful. The propeller phase is an important parameter in aero-engine power shaft 1P load analysis and he measurement method of propeller phase put forward in this paper is feasible.
