Special Issue Information
Noise generated by aircraft continues to be a pressing issue for society, as an increasing number of people residing in proximity to airports make noise complaints on a regular basis. The reduction of aircraft noise is therefore a very important engineering task that would require the careful identification of different acoustic sources around the airplane, the understanding of noise source behavior and ranking along flight trajectories, sophisticated measurement techniques, as well as robust and accurate numerical tools aimed at predicting the generation of noise, the propagation through the atmosphere, and the resulting noise impact along approach and departure flights. For an overall assessment of the situation, the situation has to be assessed along entire flight trajectories rather than assessing limited operating conditions only. Furthermore, it is highly recommended to apply multiple acoustic metrics and account for different and widespread observer locations along the flight. Only then can the overall situation be adequately captured. Obviously, this is a highly multidisciplinary effort and no single discipline can address this problem.
This “Aircraft noise” Special Issue targets research studies in that multidisciplinary context that deal with numerical or experimental investigation that range from investigation of specific noise sources to the assessment of noise generated by the overall aircraft in operation. Both basic and applied research studies involving modelling and simulations of aircraft noise will be considered for this Special Issue. Specific topics that are highly welcome are listed here:
- measurements, acoustic camera, beamforming (windtunnel, flyover)
- transition from experiment or high-fidelity simulation to flyover situation
- aircraft design
- flight procedure
- computational aeroacoustics
- fast prediction and scenarions (multiple flights)
- perception influenced design and annoyance studies
- uncertainties in simulation
- propeller, distributed propulsion and electrification
- supersonic flight
- jet noise
- turbofan noise
- sonic boom
