← ScienceWhich outcome occurs when exceeding design limits in jet engine?
A)Creep rupture of turbine blades✓
B)Increased bypass air volumetric flow
C)Improved combustion mixing efficiency
D)Decrease in compressor stall margin
💡 Explanation
Exceeding temperature or stress limits causes creep in turbine blades, resulting in creep rupture because the applied stress causes gradual plastic deformation. Therefore, turbine blades fail prematurely due to creep, rather than improved engine performance achieved under normal conditions.
