Sažetak
This paper presents efficiencies and losses comparison of 5 different turbofan engines for aircraft propulsion. With some exceptions these turbofan engines were generally comprised of the following components: fan, low-pressure compressor, high-pressure compressor, combustion chamber, high-pressure turbine, and low-pressure turbine. The comparison of engine components and whole engines was done using energy and exergy analysis method. The analysis showed that “Engine 1” performed with the highest energy and exergy efficiencies, while “Engine 5” performed with the lowest energy and exergy efficiencies. Engine component with the highest energy and exergy loss was the combustion chamber in all of the engines, while engine component with the highest energy and exergy efficiency proved to be the high-pressure turbine in most of the cases.
