Dynamic Propeller Balancing

The purpose of Dynamic Propeller Balancing is to balance both the engine and the propeller in concert reducing vibration levels, fatigue, and wear and tear on both the aircraft and it’s occupants. In many cases high vibration levels can lead to premature failure of critical engine components.  Excess vibration can shorten the life of expensive engine components such as avionics, vacuum pumps, exhaust systems, engine baffling, spinners, as well as internal engine components.

Dynamic propeller balancing is a process where an electronic balancer is used to measure the vibration produced by the aircraft’s power-plant and propeller.  The balancing procedure is performed on the ground, with the engine and propeller installed on the aircraft.  After analyzing the initial balance data, small trim balance weights are added to the spinner bulkhead to correct for errors and reduce the measured vibration to the lowest level practical.

Not only can dynamic propeller balancing prolong the life of your aircraft and its components, but it can also reduce the fatigue on pilot and passengers associated with vibration, making your flying much more enjoyable.
