← ScienceWhich outcome reduces jet engine thrust when ambient temperature increases?
A)Decreased air inlet mass flow✓
B)Increased turbine blade efficiency
C)Improved combustion chamber temperature
D)Enhanced nozzle expansion effectiveness
💡 Explanation
Decreased air inlet mass flow lowers jet engine thrust because hotter air is less dense, therefore reducing both the mass available for combustion and the momentum of exhaust, rather than performance improvements elsewhere in the engines.
