Abstract—The growth in demand for air transport is a problem for the global and local environment. There are, moreover, fundamental conflicts with sustainable development objectives. Sustainability demands a sustainable supply of energy without causing negative environmental impacts of aircrafts. In this paper, an investigation of energy and exergy analyses (ENEX) is reported for a MD-80 aircraft at take-off phase. In this regard, considering ENEX equations, exergy and energy efficiencies of the aircraft are found to be 29.8% and 11.48% respectively, while take-off thrust and specific fuel consumption of the MD-80 is to be 144 kN and 14.58 g (kN.s)-1. In addition, fuel and product exergies of the aircraft are calculated to be 93.92 MW and 28.06 MW.
Index Terms—sustainable aviation, aircraft, green aircraft, exergy, energy
