This video walks through the basics of vibration in aircraft engines. The cause of engine vibration is discussed using illustrations to show the offset center of mass around the engine shaft and how it can cause vibrations within the engine.
The impacts of engine vibrations are highlighted and include:
- potential failure of fluid fittings
- structural fatigue
- excessive noise
- uncomfortable vibrations felt by passengers
- increased engine wear
- additional fuel costs
The science (acceleration, velocity, displacement) and tools used to measure engine vibrations are shared with viewers. The definition of excessive vibration (based on the FAA) is highlighted and along with techniques to correct engine vibration to improve the longevity of both your aircraft and its parts along with the safety of your passengers and cargo.
