Airport noise forecasting to 2050: Integrating the Blended Wing Body concept

This paper presents a comprehensive noise mapping study for a Western European Airport in the year 2050, with a focus on incorporating the novel Blended Wing Body (BWB) aircraft. The BWB's noise data, simulated with CARMEN, and NPD data are generated to integrate the future aircraft concept into the conventional noise mapping software SoundPLAN. Subsequently, the BWB is integrated into the 2050 baseline scenario forecast, replacing wide body generation 2 aircraft, encompassing air traffic uptake, technology evolution, and fleet shifts. The results show smaller L d e n = (A) and L n i g h t = (A) contour lines when the BWB generation 3 aircraft makes up of the operations at Dublin Airport. From 2023 to 2050 air traffic is expected to increase around . This forecast shows an increase of around in L d e n and in L n i g h t contour areas in the same time frame. Area and population exposure estimates are presented for 2050 and compared to 2023. • Noise emissions for a BWB were calculated using CARMEN. The resulting NPD data was integrated in SoundPLAN. • A future scenario with air traffic increase and technology uptake was simulated for Dublin Airport for 2050. • Noise maps were generated for Dublin airport in 2050 evaluating the impact of generation 3 aircraft.
