What is the main difference between buffet and flutter?
What is the main difference between buffet and flutter?
- Buffet is a random vibration, while flutter is a harmonic vibration.
- Buffet is associated with separated airflow, while flutter is caused by turbulent air.
- Buffet is a low-level vibration, while flutter can cause structural failure.
- Buffet is caused by aerodynamic excitation, while flutter is an unstable condition caused by unsteady aerodynamics. (correct)
