The effect of aircraft engine exhaust gases on the environment

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 ...

A method to extend flamelet manifolds for prediction of NOx and long time scale species with tabulated chemistry

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 ...

Entropy approach for mitigation of environmental aviation impact and airport capacity increase

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 ...

NO x emission model of turbofan engine

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 ...

Calculation of domestic flight-caused global warming potential from aircraft emissions in Turkish airports

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 ...

Calculation of HC, CO and NO
x
from civil aviation in Turkey in 2012

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 resulted in an emission problem. Considering its impact on regional air quality, the growing emission amounts are at a non–negligible level. We especially take the busiest airports ...

Coasian economics and the management of international aviation emissions

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 ...

Innovation towards tourism sustainability: climate change and aviation

A wide range of publications has shown that the tourism sector is increasingly environmentally unsustainable. This is mainly caused by the contribution of aviation to a large and growing amount of Greenhouse Gas (GHG) emissions by tourism. In the light of this, we present an overview of developments in the aviation sector and discuss current options for innovation towards sustainability in three ...

The sustainable development of Heathrow Airport: model inter-comparison study

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) ...

The impact of an airport on regional air quality at Munich, Germany

In May 1992, the new airport in Munich, Germany, became fully operational. In 1991, two research programmes within the Bavarian Climate Research Programme (BayFORKLIM) in Germany/Bavaria were established to measure, calculate and model the assumed change of the air quality in the vicinity of the new airport. By analysing the synoptic and local weather situation, measured and modelled air ...

Canarina CUSTIC software · noise pollution modeling · algorithms 1

8. Mathematical algorithms The mathematical model that the software uses provides options to model noise emissions from a wide range of sources that might be present at industrial areas and urban areas. The basis of the model is the linear sound propagation equation, which is used to model simple point source emissions from vehicles, industries, aircrafts,… Emission sources are ...

Developments in ADMS-Airport to take account of near field dispersion and applications to Heathrow Airport

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 ...

Comparison of measured and modelled NO2 values at Zurich airport, sensitivity of aircraft NOx emissions inventory and NO2 dispersion parameters

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 ...

Investigation of environmental impact caused by aircraft engines

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 ...

Characterization of particulate matter and gaseous emissions of a C-130H aircraft

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 ...

Rising to the Challenge: The Future of Flight And How We Get There Explained in Pictures

Since the first engines developed by CFM International entered service in the early 1980s, the joint venture between GE and Safran Aircraft Engines has reduced their fuel consumption and CO2 emissions by 40% compared with the engines they replaced. The company said today that it plans to slash those numbers by another 20%, which would represent the greatest decarbonization gain the partners have ...

An application of backscatter Lidar to model the odour nuisance arising from aircraft tyre smoke

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 ...

Time to stop subsidising the most polluting form of transport

Late last month, the World Trade Organisation told the USA and the EU what it thinks of US subsidies to Boeing (story, page 2). Last June, the WTO delivered a similar verdict on EU subsidies to Airbus. Of course both sides claim that the other’s subsidies are worse – we can’t yet check these claims because the WTO report won’t be published for another few weeks, but it is ...
