← TechnologyWhich consequence results when surface de-icing fails on turbine blades?
A)Disrupted airflow reduces lift.✓
B)Increased drag causes turbine stall.
C)Blade resonance causes structural failure.
D)Excessive cooling causes brittle fracture.
💡 Explanation
When de-icing fails, ice accumulates and the distorted blade shape causes separation. This reduces the angle of attack and disrupts the boundary layer, causing the lift coefficient to drop because separation reduces lift generation, therefore output decreases rather than turbine stall.
