Vibration is hard on your aircraft and passengers. Vibration causes fatigue cracks, premature instrument failure, accelerated bearing wear, and even consumes engine power.
Balancing a propeller is a lot like balancing the tires on your car. Sensors measure vibration magnitude and use precise timing to determine where weight is needed.
(from image above)
Rotational Speed: 2309 RPM
Vibration Magnitude: 0.90 IPS (Inches Per Second)
Heavy Location: 132° from the accelerometer reference location
Remove weight from the 132° location because it is too heavy.
Or add weight at 312°, directly across from the heavy location.
Repeat process until the vibration is below 0.10 IPS
The GX gets smarter with each run and learns how your specific aircraft responds to weight adjustments.
The GX tells you precisely how much weight is needed, and where. Automated solutions mean fewer runups and less time per balance.
Sometimes the source of vibration isn't just the propeller assembly. Looking at the full spectrum of frequencies can help pinpoint each vibration component by considering the frequency ratio to propeller RPM.
