Abstract

In this study, the kerosene fueled turboprop engine of a freight aircraft is investigated along with exergy dynamic, sustainability, and thermodynamic-based environmental and enviroeconomic analyses under 7 different flight phase points (starting from 1 to ending at 7) and 5 different flight phases during a flight cycle which is assumed to be performed per one day. It is found that maximum (88.756%) and minimum (0.492%) exergetic improvement potential ratios are found in the flight phase point 3 for the burner and intermediate-pressure turbine, respectively. Minimum exergy destruction improvement ratio (5.6%) is calculated for the high-pressure turbine at the flight phase point 3, while maximum rate (33.1%) is expressed for the burner at the flight phase point 1. Maximum released carbon dioxide emissions are found as 0.04605 kgCO(2) kN(-1) s(-1), while maximum specific fuel consumption is 14.596 g kN(-1) s(-1) at the cruise phase between flight phase points of 4-6. Maximum environmental parameter (18,418.66 kgCO(2) day_cycle(-1)) and emitted carbon dioxide price (2136.56 euro day_cycle(-1)) are found between the flight phase points of 4-6 (cruise flight phase), while corresponding minimum rates are determined as 73.08 kgCO(2) day_cycle(-1) and 8.48 euro day_cycle(-1) in the takeoff phase between flight phase points of 1-2, respectively.
