Abstract
In this study, energy of lift has been calculated for five different hypothetical aircraft engine types in two condition, i- cruise at 8,000ft (2,440m) and ii- climbing at the sea level. Energy analysis is a powerful tool to provide the effective use of energy and to decrease environmental impacts caused by aircrafts as well as other systems. Energy destructions have occurred mostly at the engine components both at the climbing and the cruise conditions. In addition, wings and propellers are the second and third components, respectively, in terms of energy destruction. The less energy of lift was found in the higher aspect ratio of aircraft. The biggest energy destruction rate is equal to 32 kW approximately in the engine that has the second big size. The engine having the biggest power has the maximum energy destruction rate, 473 kW, while climb conditions. As a result of this study, it is concluded that the engines with higher power and fuel mass flow rate have bigger energy destruction rates within their components in terms of the energy of lift; 316 kW destruction in the engine component, 77 kW destruction in the wing component, 25 destruction kW in the propeller component for O-540-J3C5D engine which has 175 kW power.
