← ScienceWhich effect results on a jet engine when ambient temperature increases at constant throttle?
A)Thrust decrease and EGT increase✓
B)Thrust increase and fuel decrease
C)EGT decrease and thrust increase
D)Fuel increase and thrust decrease
💡 Explanation
When ambient temperature increases the density decreases, affecting the mass flow rate; thermal efficiency is reduced. Constant throttle means less dense air, thus thrust decreases because of reduced mass flow, and Turbine Gas Temperature/Exhaust Gas Temperature will increase, rather than other outcomes.
