Assuming that the turbine inlet temperature of a gas turbine engine remains constant, which of the following operating parameter changes would be noted with an increase in the compressor inlet air temperature?

Correct Answer: Option D — The gas turbine power would drop due to reduced mass air flow.

Gas turbine power output is directly proportional to the mass flow of air through the engine. An increase in compressor inlet temperature reduces air density; consequently, the mass flow decreases. With a constant turbine inlet temperature, the reduced mass flow results in a direct loss of total power output.
