The aero-propeller will vibrate in high-speed rotation. The way of resisting vibration is to perform a dynamic balancing procedure to this propeller. Compared with the traditional balancing algorithm

this algorithm of modeling balancing based on the feature model of the propeller to be balanced

and with the vector decomposition algorithm

enables to accurately calculate the total amount and the installing positions of counterweights to be installed

thus effectively solving the actual problem of inconformity between the positions of actual light-spot and preset counterweights on the propeller to be balanced in engineering practice. The practice result shows that it is easy to reduce the vibration level of the propeller to the "best" range of less than 1.27×10-3m/s(0.05IPS) with the modeling balancing algorithm

and absolutely keep the vibration level within acceptable range with only one balancing for the qualified threshold value of not more than 4.826×10-3m/s(0.19IPS).
