Estimating Emissions of Harmful Exhaust Components by Aircraft Engines During the Takeoff and Landing Cycle in Airport Space

Composition and morphology of particle emissions from in-use aircraft during takeoff and landing.

In order to provide realistic data for air pollution inventories and source apportionment at airports, the morphology and composition of ultrafine particles (UFP) in aircraft engine exhaust were measured and characterized. For this purpose, two independent measurement techniques were employed to collect emissions during normal takeoff and landing operations at Brisbane Airport, Australia. PM1 e...

Hydrocarbon emissions from in-use commercial aircraft during airport operations.

The emissions of selected hydrocarbons from in-use commercial aircraft at a major airport in the United States were characterized using proton-transfer reaction mass spectrometry (PTR-MS) and tunable infrared differential absorption spectroscopy (TILDAS) to probe the composition of diluted exhaust plumes downwind. The emission indices for formaldehyde, acetaldehyde, benzene, and toluene, as wel...

Reduction Emission Level of Harmful Components Exhaust Gases by Means of Control of Parameters Influencing on Spraying Process of Biofuel Components for Aircraft Engines

The aim of the research is to test the fuel additives which decrease dimensions of atomised fuel drops, by applying changes to the specific parameters which impact the atomisation process. Those parameters include density, surface tension, viscosity and the viscosity index. Dimensions of drops of biofuels are much bigger compared to hydrocarbon fuels. By modifying the physical and chemical para...

Competition for Scarce Inputs: The Case of Airport Takeoff and Landing Slots

The process of deregulating airlines in the United States began in earnest with the passage of the Airline Deregulation Act of 1978. The Act set in place a timetable for removing government controls on fares and entry into routes. However, airline access to airports has not been fully deregulated. In 1968, the Federal Aviation Administration (FAA) adopted the socalled "high-density rule" to com...
