← ScienceWhich outcome results when turbulent flow exceeds design limits of an aircraft wing?
A)Premature structural fatigue accumulates rapidly✓
B)Aerodynamic lift increases significantly afterwards
C)Fuel consumption minimizes predictably overall
D)Parasitic drag reduces measurably later
💡 Explanation
Premature structural fatigue accumulates rapidly because flutter (aeroelastic instability) initiates; the fluctuating pressure from turbulent flow causes the wing to vibrate at its resonance frequency: aeroelasticity. Therefore fatigue life decreases, rather than lift increasing or drag decreasing.
