Modeling and validation of temperature changes in a pouch lithium-ion battery at various discharge rates
(Pergamon-Elsevier Science LTD, 2016)This paper deals with the thermal modeling of temperature rise in a pouch lithium -ion battery with LiFePO4 (also known as LFP) cathode material. The developed model represents the main thermal phenomena in the cell in ... -
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 ... -
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 ... -
An assessment of cruise NOx emissions of short-haul commercial flights
