Abstract

In order to quantitatively evaluate the advantages, in terms of noise emissions, of the application of modern electric power-trains to airplanes, an acoustic pollution prediction model was developed. The method mixes the benefits of best-practice and physics-based noise prediction procedures and is applicable to pure-electric and serial hybrid-electric General Aviation aircraft. Numerical results corresponding to circuit patterns in the vicinity of the Milan-Bresso airport are shown, proving the significant noise reduction that flying in pure-or partially-electric mode can bring for light aircraft operating around densely populated areas.
