The invention discloses a balancing method for static balance of a helicopter blade, which comprises a blade, a blade root at the left end of the blade is fixedly connected with a blade root fixing clamp through a plurality of bolts, a blade root bottom is arranged on the force knife surface of the blade root fixing clamp, and a blade tip fixing clamp is arranged at the blade tip at the right end of the blade. An electronic balance can be arranged at the bottom of the blade tip fixing clamp, the upper surface of the blade root base and the upper surface of the electronic balance are located on the same horizontal plane, and balancing weights are symmetrically arranged on the blade tip surface of the blade in the spanwise direction of the blade. The method has the beneficial effects that the static distance value is equal to the weight * the length, and the static distance value of the blade refers to the product of the weight of the blade and the distance between the center of the blade and the rotating center of the blade. And vibration caused by the fact that the static distance values of the blades are large in difference, the difference can be amplified by countless times when the blades rotate at a high speed, and the blades are high in height and low in height is avoided.

    本发明公开了一种直升机桨叶静平衡的配平方法,包括桨叶,所述桨叶左端的桨根与桨根固定夹具通过多个插销固定连接,所述桨根固定夹具的力刀面设置有桨根底,所述桨叶右端的桨尖设置有桨尖固定夹具,所述桨尖固定夹具的底部可设置有电子天平,所述桨根底座和电子天平上表面在同一水平面上,所述桨叶的桨尖表面处以桨叶的展向方向对称布置有配重块。本发明的有益效果是:通过静距值=重量*长度,桨叶的静距值指的是桨叶的重量与桨叶之心距桨叶旋转中心距离的乘积。避免桨叶的静距值相差较大,在桨叶高速旋转时此差异会放大无数倍,造成桨叶一高一低,而引起振动。
