Track & Balance 🚁🚁 Helicopters are subject to both harmonic and resonant behavior. When troubleshooting abnormal vibrations, the variables depend on the features of each airframe. Some have lead/lag main rotor dampers or flexible energy-absorbing transmission mounts. Some have articulated, teetering or ridged rotor systems. They all have their own set of common items to look at when things don’t go well.
