Exergy analysis of a turbofan aircraft engine
(Inderscience Enterprises LTD, 2009)
An exergy analysis is reported for a General Electric turbofan engine (the CF6-80) using sea-level data. The effects on exergy efficiencies and exergy destructions are investigated of modifying the isentropic efficiencies ...
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 ...
Calculation of HC, CO and NOx from civil aviation in Turkey in 2012
(Inderscience Enterprises LTD, 2013)
To meet the growing demand for air transport, airline companies doubled their aircraft numbers in Turkey, where civil aviation activities have shown great development in recent years. This increase in aircraft numbers ...
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, ...
Estimation of vertical and horizontal distribution of takeoff and climb NOx emission for commercial aircraft
(Pergamon-Elsevier Science LTD, 2013)
An investigation of takeoff and climb NOx emissions is reported for a twin-engine, narrow-body, short-to-medium haul commercial aircraft, B737-800. Ten randomly selected flights are considered for two independent domestic ...
Metaheuristic and Machine Learning Models for TFE-731-2, PW4056, and JT8D-9 Cruise Thrust
(Walter De Gruyter GMBH, 2017)
The requirement for an accurate engine thrust model has a major antecedence in airline fuel saving programs, assessment of environmental effects of fuel consumption, emissions reduction studies, and air traffic management ...
Assessment of emissions at busy airports
(John Wiley & Sons LTD, 2010)
Emissions are determined in the vicinity of airports and used to demonstrate that aircraft movements in the airport, as measured by landings and takeoffs, are not sufficient to evaluate the cumulative emission formation ...
Exergetic analysis of an aircraft turbofan engine
(John Wiley & Sons LTD, 2007)
The main objective of the present study is to perform an exergy analysis of a turbofan kerosene-fired engine with afterburner (AB) at sea level and an altitude of 11000 m. The main components of this engine include a fan, ...
Impact of aircraft performance differences on fuel consumption of aircraft in air traffic management environment
(Emerald Group Publishing Limited, 2004)
Performance differences between the aircraft types are natural and they inevitably cause problems in the air traffic system, particularly when slower aircraft types are followed by faster types in a climb or cruise queue. ...
Energy and exergy (ENEX) analyses of a MD-80 aircraft
(International Journal of Mechanical Engineering and Robotics Research, 2016)
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 ...
