Helicopter Applications.
•
Smart Chart main rotor
track & balance.
•
Tail rotor track and
balance.
•
Tail rotor shaft balance.
•
Engine vibration analysis.
•
High speed shaft balance.
•
Vibration absorber check &
adjustment.
•
Data collection for trend
monitoring.
•
Stand alone operation for
"random" balance point,
spectrum, or
other measurements.
Prestige Helicopters supports all of
these capabilities, and track & balance
procedures can be carried out at the location of
your choice. |

wear, normal stress and dirt build up all conspire
against your balance. Even normal seating of bearings
and properly torqued components settle into different
balance issues. Have your machine rebalanced frequently,
and you'll notice the feel, but you'll love the reduced
parts replacement. |

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, carburetor, and mixture linkages). |
