Although recent studies have pointed out the circular economy (CE) as one of the main
trends in environmental sustainability, little is known about its applications in the aerospace …

In this study, energy, exergy, and sustainability analyses are performed for the PW4056
engine to observe the different fuel effects on the thermodynamic performance of a turbofan …

As sustainability, increasing of fuel and energy efficiency has become a greater concern in
aircraft design and fleet operation for two decades. To meet this need, a new methodology is …

For next generation aircraft, Variable Cycle Engine (VCE) is a candidate to fulfil the multi-
mission requirements of flight. This new concept is promising to complete deficiencies of …

Studying efficiency and emissions of an aircraft engine at cruise phase is of high importance
so as to help in finding optimum flight conditions. Especially, since exhaust emissions from …

Combustors of gas turbine engines have generally the highest irreversibility due to the
combustion process. Therefore, to observe influence of air to fuel ratio (AFR) on combustor …

The four different piston-prop engines (PPE1, PPE2, PPE3, PPE4) are investigated along
with thermodynamic (energy and exergy), thermoenvironmental (based on exergy), and …

In the present paper, an extensive energetic and exergetic assessment of a turbojet engine
powered by biofuel, hydrogen and JP-8 fuels is performed in view of the thermodynamic …

In the current study, advanced exergo-dynamic analysis of a micro-turbo jet (μ-jet) along with
conventional exergy analysis is presented in various running shaft speed modes. In this …

Energy security and low environmental impact issues become hot topics due to usage of
small-sized turbojet engines in many areas. In this study, thermodynamic analysis of target …
