Propulsion • Thermodynamic Cycles of Gas Turbines • Brayton Cycle & Component Efficiencies
In a real gas turbine engine, which component efficiency accounts for viscous boundary layer losses and shock losses across rotating rotor blades?
(A) Isentropic compressor efficiency
(B) Combustion efficiency
(C) Mechanical transmission efficiency
(D) Propulsive efficiency
Answer Key:
A
Step-by-Step Verified Solution
### Solution: Isentropic compressor efficiency quantifies aerodynamic and viscous losses within the blade rows by comparing actual enthalpy rise to ideal isentropic enthalpy rise. Correct: A.
