Aircraft Noise: Annoyance, House Prices and Valuation [PDF]

open access: yes, 2006
“Nobody wants to buy your house. It’s the aircraft noise. You’ll have to reduce the price a lot.” Aircraft noise around airports causes annoyance, and tends to reduce the price of affected properties.

The UK Aircraft Noise Index Study: 20 Years on. [PDF]

open access: yes, 2004
In the early 1980s the UK Department of Transport (now the Department for Transport: DfT is used here to cover all its incarnations) commissioned a study to determine what index should be used to assess aircraft noise disturbance near major airports ...

Civil Aircraft Design Priorities: Air Quality? Climate Change? Noise? [PDF]

open access: yes, 2006
A variety of related questions is posed. Are the right priorities for future aircraft design being set now? New civil aircraft types could be ‘silent’, ie make much less noise than current types. They could be ‘green’, ie safeguard the environment.

Torsional vibration analysis of shaft with multi inertias

open access: yesScientific Reports, 2022
An analytical method is proposed to investigate the torsional vibration of the uniform circular shaft with multiple concentrated inertias. The governing equation is established based on the Hamiltonian principle and verified by the dynamical method.

Regional sensitivities of air quality and human health impacts to aviation emissions

open access: yesEnvironmental Research Letters, 2020
Emissions from civil aviation degrade air quality, and have been estimated to lead to ∼16 000 premature deaths annually. Previous studies have indicated that aviation emissions in different regions have varying corresponding air quality and human health ...

An advanced method of contributing emissions to short-lived chemical species (OH and HO2): the TAGGING 1.1 submodel based on the Modular Earth Submodel System (MESSy 2.53) [PDF]

open access: yesGeoscientific Model Development, 2018
To mitigate the human impact on climate change, it is essential to determine the contribution of emissions to the concentration of trace gases. In particular, the source attribution of short-lived species such as OH and HO2 is important as they play a
