← ScienceWhich outcome causes increasing jet engine rpm past design limits?
A)Compressor surge leads to increased cavitation
B)Flameout causes thermal shock to turbines
C)Flutter causes compressor blade fracture✓
D)Increased boundary layer becomes turbulent
💡 Explanation
Flutter causes compressor blade fracture because exceeding design rpm raises airflow velocity above the structural limit. This induces aeroelastic instability i.e. flutter, therefore blades fatigue and fail, rather than cavitation in fuel lines, as flutter depends on achieving a critical Reynolds number.
