Dynamic Propeller Balancing...
Propellers, spinners, crankshafts and other dynamic components are manufactured to strict tolerances. However, due to centrifugal force, aerodynamic loading and individual component tolerances some residual "out of balance" can be present.
It has been determined that dynamic trim balance can correct such "out of balance" and results in significantly lower vibration levels. Because the vibration caused by an out of balance propeller is low to medium frequency, typically in the 15-45 Hz range, it is often felt throughout the airframe, usually at a lower amplitude than exists at the engine.
All propellers can benefit from dynamic balance. When properly executed the balance has both short and long term benefits.
In the short term, there is usually an immediate reduction in the noise and vibration "feel" in the cabin.
Long term benefits are a reduction in the cycle fatigue of airboxes, exhaust stacks, radio equipment, sheet metal and cowling cracking and a reduction in wear of controls linking fixed portions of the airframe with the engine (i.e. RPM control, carburettor, and mixture linkages).
