← ScienceWhich consequence results when increased quenching in a jet engine turbine?
A)Reduced thermal efficiency✓
B)Elevated compressor stall risk
C)Decreased fuel consumption
D)Increased turbine blade creep
💡 Explanation
Increased quenching creates larger temperature gradients, favoring transient cooling at the expense of combustion stability. This reduces the available enthalpy for conversion through the Brayton cycle due inefficient combustion conditions; therefore engine efficiency is reduced, rather than alternatives based only on mechanical failures.
