Modeling the fuel flow-rate of transport aircraft during flight phases using genetic algorithm-optimized neural networks
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2016)
Predicting the fuel consumption of transport aircraft is vital for minimizing the detrimental effects of fuel emissions on the environment, saving fuel energy sources, reducing flight costs, achieving more accurate aircraft ...
Analysis of a quantum irreversible Otto cycle with exergetic sustainable index
(Elsevier Science BV, 2016)
In this study, exergetic sustainability index is applied to quantum irreversible Otto cycle with -1/2 spin system. Exergetic sustainability index in a quantum engine is used first time. This index is the ratio of exergy ...
Analysis of a nano-scale thermo-acoustic refrigerator
(Elsevier Sci LTD, 2016)
Purpose of this study is to analyze a nano scale thereto-acoustic refrigeration cycle in terms of its thermodynamic performance. A nano scale thermo-acoustic refrigerator operating with Maxwell-Boltzmann gas and He is ...
Determination of optimum insulation thickness for building's walls with respect to different insulation materials: a case study of International Hasan Polatkan Airport terminal
(Inderscience Enterprises LTD, 2018)
The systems in which energy is most intensely used in airport terminal buildings are HVAC systems. More efficient heating and cooling systems and the performance of the building envelope can provide significant reductions ...
An assessment of cruise NOx emissions of short-haul commercial flights
(Pergamon-Elsevier Science LTD, 2017)
Cruise NOx emissions of aircraft are an important input parameter for studies investigating climate change due to their ability to alter the concentrations of certain trace gases, such as ozone, methane, and hydroxyl in ...
Analysis of Test-Cell Emission Measurements of Newly Overhauled Turbofan Engines
(Amer Inst Aeronautics Astronautics, 2015)
In this study, the gaseous emissions of newly overhauled CFM56-3B1 and -3B2 series turbofan engines are measured in a test-cell environment during typical functional and performance test procedures. The measured emissions ...
Effect of Climb Angle on Aircraft Fuel Consumption and Nitrogen Oxides Emissions
(Amer Inst Aeronautics Astronautics, 2018)
Departure climb angles differ with respect to factors such as obstacles within the departure track, meteorological conditions, and cost index input, most of which have a dynamic nature to some extent. In this sense, it is ...
Effects of Ambient Air Temperature on Gaseous Emissions of Turbofan Engines
(Amer Inst Aeronautics Astronautics, 2016)
This study presents the results of analyses related to the effects of ambient air temperature (ranging from 5.2 to 23.9 degrees C) on certain engine performance parameters and gaseous emissions, carbon monoxide and nitrogen ...
NOx, fuel consumption and time effects of flight path angle during descent
(SAGE Publications LTD, 2013)
Due to factors affecting flight operation and air traffic management, such as air traffic separation, avoidance of traffic from congested areas, or facilitating separation with crossing traffic, as well as environmental ...
Relationship between fuel consumption and altitude for commercial aircraft during descent: Preliminary assessment with a genetic algorithm
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2012)
Despite fuel flow rates being low during descent compared to climb and cruise, the potential exists for significant fuel savings during that phase of flight. Increased fuel use, costs and related environmental impacts are ...
