A Calculation Method of Static Balance of 3-blade Propeller
In view of the special angle between the blades of a 3-blade propeller in the horizontal plane,a static balance calculation method suitable for full-blade propeller is proposed.Bearing unloading is used to detect the imbalance torque,compensate for the initial imbalance of the system,eliminate the influence of bearing friction on balance detection in the limited range,programming the magnitude and direction of imbalance torque of the propeller displayed on the HMI of the host computer,thus solve the problem of inaccurate propeller imbalance detection.Design the vector decomposition of the imbalance torque to solve the problem of noncoincidence between direction of imbalance and the blade.
