← ScienceWhich consequence results when turbine blade erosion occurs in a jet engine?
A)Decreased engine compression ratio✓
B)Increased fuel combustion efficiency
C)Reduced exhaust gas temperature
D)Improved engine thrust performance
💡 Explanation
Erosion increases blade tip clearance, causing a loss of compressed air via the mechanism of tip leakage; because compressed air escapes, the engine's compression ratio decreases as a result, rather than improved thrust or fuel use, which requires tight seals.
