Exergetic sustainability assessment of a HALE UAV using dodecene fuel
(Inderscience Enterprises LTD, 2016)
Exergetic sustainability performances of a high altitude long endurance (HALE) unmanned aerial vehicle (UAV), having a single turbofan engine and using dodecene as its fuel were investigated all along its flight profile, ...
Entropy Generation Calculation of a Turbofan Engine: A Case of CFM56-7B
(Walter De Gruyter GMBH, 2018)
Entropy generation and energy efficiency of turbofan engines become greater concern in recent years caused by rises fuel costs and as well as environmental impact of aviation emissions. This study describes calculation of ...
Effect of reference altitudes for a turbofan engine with the aid of specific-exergy based method
(Inderscience Enterprises LTD, 2012)
This paper presents effect of reference altitudes on the exergetic efficiency of a engine with the aid of specific exergy method. between 4000-9000 m. In the analysis, and exergy efficiency of the engine is found to be ...
Sustainability assessment of PW6000 turbofan engine: an exergetic approach
(Inderscience Enterprises LTD, 2014)
In this paper, theory, methodology and example application are developed and shown for a PW6000 high-bypass turbofan engine in terms of exergo-sustainable perspective. To obtain exergetic sustainability indicators, first, ...
Exergetic sustainability improvement potentials of a hydrogen fuelled turbofan engine UAV by heating its fuel with exhaust gasses
(Pergamon-Elsevier Science LTD, 2016)
Exergetic sustainability parameters such as, exergy efficiency, waste exergy ratio, environmental effect factor and exergetic sustainability index were investigated for an UAV having a turbofan engine for the case its ...
An exergy way to quantify sustainability metrics for a high bypass turbofan engine
(Pergamon-Elsevier Science LTD, 2015)
As fuel efficiency becomes a greater concern in aero engine design and operation. To meet this need, a new methodology is being developed here that proposes the use of exergetic metrics for mapping the exergy flows throughout ...
Using emission index to determine energy efficiency and environmental parameters of a turbofan engine at various flight phases
(Inderscience Enterprises LTD, 2016)
In this study, an unordinary methodology for energy efficiency calculation of a turbofan engine is introduced. Emission indexes of the engine are used to find out energy efficiency and novel parameters for environmental ...
Exergetic Sustainability Indicators as a Tool in Commercial Aircraft: A Case Study for a Turbofan Engine
(Taylor & Francis Inc, 2015)
This paper focuses on the exergetic sustainability indicators of a medium-range commercial aircraft engine for constant reference environment and ground running conditions. First, a detailed exergy analysis of turbofan ...
Exergetic performance of a low bypass turbofan engine at takeoff condition
(Springer International Publishing, 2014)
In this article, exergetic methodology is applied for a low bypass turbofan engine at maximum power setting. The engine is a low-bypass (0.96–1) turbofan engine and its variants fitted to the 737-100/200 all comprise six ...
Assessment of degradation effects for an aircraft engine considering exergy analysis
(Pergamon-Elsevier Science LTD, 2017)
Despite the improvements in engine technology, the combustion processes and wear occurred in engine components affect performance adversely. The turbine and compressor fouling, degradation mechanisms such as erosion, ...
