Question 101Gas Turbine - Assistant Engineer

70% to pass

A gas turbine engine in which exhaust gas heat energy is added to the compressor air charge before entering the combustor, is classified as which of the following?

AReheat cycle.
BRegenerative cycle.
CCombined cycle.
DICR cycle.
AI Explanation

The correct answer is B) Regenerative cycle. In a regenerative cycle gas turbine engine, the exhaust gas heat energy is used to preheat the compressed air before it enters the combustor. This improves the engine's overall thermal efficiency by reducing the amount of fuel required to achieve the desired turbine inlet temperature. The other answer choices are incorrect because: A) Reheat cycle refers to reheating the exhaust gases between turbine stages, C) Combined cycle involves combining a gas turbine with a steam turbine, and D) ICR cycle stands for Intercooled Recuperated cycle, which is a different configuration involving an intercooler between compressor stages.
