The invention discloses a laser common taper measurement system for a helicopter rotor, relates to the technical field of precision measurement, and aims to solve the problems that at least ten pulse signals need to be introduced to participate in calculation of time intervals and blade waving taper parameters in an existing laser measurement method, an indirect measurement method is adopted, and the measurement uncertainty reaches 0.5 mm. According to the method, the laser distance measuring sensor and the timestamp concept are utilized, the height and the cutting time of the rotor blade are directly measured through a non-contact measurement method of blade cutting laser beams, only two signals are needed to participate in calculation, and the uncertainty of measurement of the flapping and shimmy characteristic parameters of the rotor blade is not larger than 0.1 mm.
一种直升机旋翼激光共锥度测量系统,涉及精密测量技术领域,针对现有激光测量法需引入至少10个脉冲信号参与计算时间间隔和桨叶挥舞锥度参数,属于间接测量的方法,测量不确定度达到了0.5mm的问题。本申请利用激光测距传感器和时间戳概念,通过桨叶切割激光光束的非接触测量方法对旋翼桨叶高度和切割时间进行直接测量,本申请仅需2个信号参与计算,使得旋翼桨叶挥舞和摆振特性参数测量不确定度不大于0.1mm。
