← TechnologyWhich outcome results when nacelle ice accretion disrupts airflow over a wind turbine's blades?
A)Lift decreases proportionally to icing✓
B)Blade stall angle unpredictably increases
C)Vibration fatally excites the tower
D)Yaw misalignment significantly reduces capture
💡 Explanation
Icing changes the aerofoil shape reducing performance because flow separation occurs earlier; therefore lift decreases proportionally to icing and thrust production drops, rather than causing stall angle changes or exciting tower resonances.
