A gas-turbine engine operates with 2-stage compression and 2-stage expansion. It receives incoming nir at 100 kPa and 25°C before the air passes through a regeneration, reheating and intercooling processes. Across each compressor, the pressure ratio is 3,8, with 300 kJkg of heat are received by the air at cach combustion chamber. The generator is operating perfectly and increases the cold air temperature by 22°C. Assaming iseniropie operations during compression and expansion stages, with constant speuific heats at room temperature, evaluate the system's thermal efficiency.

The term "engine" indicates a mechanical device/machine used to convert input energy to a specific mechanical output. The input energy may be in the form of chemical energy, thermal energy, or so on and mechanical output is in the form of mechanical energy (work done). Generally, the engines classify into two groups which are internal combustion type and external combustion type, and further, these two types can be classified into two types that are reciprocating and rotary engines.
