Profile Aircraft Noise and Climate Effects (ANCE)

The section Aircraft Noise and Climate Effects (ANCE) studies the environmental impact of aviation through developing accurate models for the prediction of aircraft noise, emissions and climate effects. Aircraft noise continues to be a very serious source of disturbance to the public. Also, the current contribution of aircraft emissions to global warming is estimated to lie in between 1.5 and 5.5%, but is predicted to increase significantly. In addition, the level of scientific understanding of the climate effects of aviation is low. The vision of ANCE is that for the growth of aviation (5 % per year) to be sustainable with a decreasing impact on the environment, more accurate modelling of the impact due to noise and emissions is required. ANCE has two knowledge clusters:

Aircraft Noise

For aircraft noise, the modelling chain comprises the acoustic source, that is the aircraft, via the propagation medium, that is the atmosphere, to the final noise impact as perceived on the ground.Research topics include:

  • Weather-dependent noise contour modelling, fully accounting for the temperature and wind speed gradients in the atmosphere
  • Detailed aircraft noise source modelling, both considering the engines and airframe, also for the assessment of new aircraft technologies
  • Acoustic camera imaging for noise source identification on aircraft and in more fundamental aero-acoustic research in wind tunnels

The aircraft noise research is carried out in close cooperation with NLR and DLR. 

Studies of the effects of aircraft emissions on climate change

Here the approach is to use models capable of assessing the aviation induced climate effects by calculating the contribution of the individual climate agents (CO2, NOx, contrails, O3). This enables the assessment of the effectiveness of mitigation measures such as changing flight settings or supersonic flying. This research is executed in close cooperation with DLR.
