Question 102Gas Turbine - Assistant Engineer
70% to passA gas turbine engine in which exhaust gas heat energy is added to the air charge between the compressor and combustion chamber is classified as which of the following?
AOpen cycle engine.
BClosed cycle engine.
CSemi-open cycle engine.
DRegenerative cycle engine.
AI Explanation
The correct answer is D) Regenerative cycle engine. In a regenerative cycle engine, the exhaust gas heat energy is used to preheat the air charge between the compressor and combustion chamber, improving the engine's efficiency. This is a key feature that distinguishes the regenerative cycle from the open cycle (A) and closed cycle (B) engine types. The semi-open cycle (C) is not a recognized engine classification, so it is not the correct answer. The other options do not accurately describe the use of exhaust gas heat recovery that characterizes the regenerative cycle engine.
