← TechnologyWhich outcome occurs when de-icing fluid warms turbine blades during landing approach?
A)Aerodynamic stall reduces landing speed
B)Creep resistance temporarily decreases minimally✓
C)Blade icing protection system becomes operational
D)Compressor efficiency abruptly improves markedly
💡 Explanation
The warm de-icing fluid briefly elevates blade temperature, and therefore `thermally activated creep` strain accumulates because heat increases atomic diffusion; therefore creep strain accumulates temporarily; rather than abrupt stall, that would need an icing event causing separation.
