Dynamic Propeller Balancing
What is it?
Dynamic propeller balancing is a procedure where a digital vibration
analyzer is used to measure the vibration produced by the aircraft powerplant
and propeller assembly and identify the source(s).
Small trim balance weights are then added to the propeller spinner
or flywheel to correct for imbalance and reduce the measured vibration to the lowest level practical. On average,
4 out of 5 fixed-wing aircraft can benefit from Dynamic Prop Balancing.
"But my aircraft runs fine. Why should I have the propeller balanced?"
Your aircraft's vibration level may be
better or worse than the average but it's best to know for sure and fix it
if it is. 4
out of 5 aircraft tested are experiencing high levels of vibration which
can be quickly diagnosed and eliminated or reduced to safe levels.
When your prop shop statically balances your prop you should
follow up with a dynamic balance ON THE AIRCRAFT. - and we're about the
ONLY company that's doing it properly - using TWO sensors.
We've found that if you only sense at the front and balance it
down to zero, you often have vastly increased the vibration at the back
and you can't tell unless you're sensing there too! Most shops and
prop balancing outfits have old equipment and a single sensor and are
entirely unaware of this limitation!
The
following pictures show typical balancing installations. You can see the 3
sensors. (the third one measures propeller position).
