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 ...
An Analysis of Vertical Profiles of Wind and Humidity Based on Long-Term Radiosonde Data in Turkey
(2016)
The prediction of atmospheric variables is fundamentally important for flight, and efficiency with environmental impact analyses of aircraft. However, certain variables are less predictable leading to inefficient utilization ...
Fuel flow analysis for the cruise phase of commercial aircraft on domestic routes
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2014)
From the point of view of the environmental impact of aviation, rather than fundamental strategies mainly intended for lower fuel consumption, and thereby less carbon dioxide emissions, more comprehensive approaches have ...
The effect of flight distance on fuel mileage and CO2 per passenger kilometer
(Taylor & Francis Inc, 2019)
In this study, the effect of distance on fuel mileage (fuel burn per nautical mile) and CO2 intensity, based on a large amount of actual flight data, is discussed for narrow-body commercial aircraft performing domestic ...
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 ...
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 ...
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 ...
An Analysis of the Effect of Non-Payload Weight on Fuel Consumption For a Wide-Bodied Aircraft
(2017)
Fuel flow rate of an aircraft varies significantly during a typical flight, mainly due to required engine thrust, speed, weather conditions, aircraft configuration and aircraft mass. Of these, the effect of aircraft mass, ...
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 ...
Energy and emission assessments of continuous descent approach
(Emerald Group Publishing Limited, 2010)
Purpose - Continuous descent approach (CDA) is a method, which allows the aircraft flying its individual optimal vertical profile down to runway threshold with engines operating at low-thrust power. The main objective of ...
