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). |
