Rotor Balancing (coaxial scheme)

Helicopters

After the helicopter had been assembled, it underwent the standard procedures of blade tracking and main rotor dynamic balancing. However, the crew still experienced a very uncomfortable level of vibration.

Risinājums.

Secinājums

Based on the results of trial balancing using a 3-axial accelerometer and RL-R19, the helicopter manufacturer modified their balancing method. Now all the helicopters they produce are balanced regarding the level of vibration on three axes.
