← ScienceWhich limit constrains burning efficiency in jet engines?
A)Carnot cycle efficiency limit✓
B)Combustion stoichiometric air ratio
C)Turbine blade tensile strength
D)Air intake sonic choking
💡 Explanation
The Carnot cycle efficiency limit dictates maximum possible heat-to-work conversion because no real engine is perfectly reversible, therefore heat losses reduce efficiency, rather than other mechanical or combustion design parameters doing so directly.
