The gaseous and nonvolatile particulate matter (PM) emissions of two T56-A-15 turboprop engines of a C-130H aircraft stationed at the 123rd Airlift Wing in the Kentucky Air National Guard were characterized. The emissions campaign supports the Strategic Environmental Research and Development Program (SERDP) project WP-1401 to determine emissions factors from military aircraft. The purpose of the ...

During last decade a lot of investigations also focused on the evaluation of aircraft engine impact on local and regional air quality in the vicinity of the airport. The emission inventory of aircraft engines are usually calculated on the basis of certificated emission indexes, which is provided by the engine manufacturer and reported in the database of ICAO. The certificated emission indices ...

The environmental effects of exhaust gas emissions from different types of spark ignitions (SIs) - naturally aspirated and air–cooled from piston–prop aircraft engines - at the landing and take–off (LTO) phase of flight–based operations are investigated in this study. The minimum natural resources effect was determined to be 1.37 MJ surplus energy/LTO in 320 in three cylinder displacement and ...

The sources of air pollution are classified as point, line and surface sources. Motor vehicle pollution is modelled as a line source. Hitherto, studies of air pollution have emphasised surface pollution caused by fossil fuel burning for the purposes of obtaining energy and heating, and motor vehicle pollution studies are usually concentrated on land vehicles. In this study, the effect of aircraft ...

These are heady times for the commercial-aircraft business at Airbus and Boeing, as airlines place huge orders for new planes. Each is working on more fuel-efficient aircraft to satisfy airlines that want lower fuel bills and regulators who want lower emissions from aircraft. Airbus Group CEO Tom Enders spoke last month to an aviation conference in Dallas and urged the industry to put more ...

In this study, global warming potential (GWP) is calculated for aircrafts used in Turkish airports. The basic idea of this study is to investigate both emissions and their GWP values. This study is conducted in three steps, namely: 1) finding busiest airports in Turkey; 2) specifying the most used aircraft types and its engines; and 3) calculation of domestic flight-caused GWP value for both the ...

The long awaited standard for aircraft CO2 emissions made further headway at a recent meeting of the UN’s International Civil Aviation Organization (ICAO). The new environmental measure was unanimously recommended by the 170 international experts on ICAO’s Committee on Aviation Environmental Protection (CAEP), paving the way for its ultimate adoption by the UN ...

The recent decision by the EU Parliament supporting an emissions tax and subsequent carbon trading scheme for European airlines provides the structural foundation for an exploration of the role of Coasian economics in emissions abatements in the international aviation industry. The paper begins by outlining Pigouvian taxation in aviation and considers, from a business context, the potential ...

This paper presents a comparison of modelled and measured annual mean NO2 concentrations around Zurich airport. Modelled concentrations were derived from the LASAT Lagrangian model for the airport and from a Gaussian plume model for the Zurich canton. The measured annual mean NO2 concentrations were monitored at stations within the airport. The modelled airport NO2 concentrations fell below 1 ...

A Rapid-Scanning Backscatter Lidar (RASCAL) has been deployed at Heathrow and Manchester Airports to collect backscatter data from particulate emissions in the wakes of several hundred flights. The principal aim of these measurements was to characterise the dispersion of the engine exhausts, but it was found that tyre smoke was also visible, giving a signal substantially greater than that from ...

The implementation of the operational procedures to reduce aircraft noise and engine emission in the airport vicinity was under consideration in the paper. Emphasis was put on optimal aircraft operational procedures for noise and emission reduction taking into account interrelations of aircraft noise and engine emission. The task of minimising of aircraft noise impact and engine emission ...

ADMS-Airport is based on the ADMS-Urban system for modelling urban air quality. In the near field it employs a quasi-Gaussian dispersion model and this is nested within a trajectory model. Aircraft sources are treated explicitly as accelerating jets. Application of the model to air quality calculations was conducted for the Model Inter-Comparison (MIC) Study of Project for the Sustainable ...

EU Environment Commissioner Margot Wallström has expressed cautious support for allowing European flights into the EU emissions trading scheme from 2008. Airport operator BAA has developed proposals to allow airlines to offset their rising emissions by buying EU allowances - and the UK Government looks likely to back the idea in its forthcoming aviation White Paper. Aviation's soaring ...

Numerical simulation is currently used to help design low NOx devices for aircraft engines. In order to improve the prediction of pollutant species, combustion models based on tabulated chemistry have been commonly used in recent years. However, the short time scales of usual flamelet manifolds can lead to errors concerning the NO prediction in post flame area, as shown in this paper. Thus, a new ...

Air quality modelling near airports has received attention due to the impact of emissions from aircrafts near ground level. This work is part of the model inter-comparison study undertaken for the Department of Transport in connection with air quality near Heathrow Airport. Results formed part of a submission to the UK government in July 2006. The Emissions and Dispersion Modelling System (EDMS) ...
