Abstract

This paper presents an integrated assessment of aircraft noise in flight and ground operations within the EFACA project, supporting the roadmap toward ACARE Flightpath-2050 noise goals. It summarizes required reductions, evaluates current technology readiness, and analyzes contributions from advanced propulsion concepts, propeller-noise modeling, and operational procedures. New seven-bladed propeller designs, validated through semi-empirical, analytical, and CAA methods, demonstrate substantial tonal-noise improvements, influencing the aircraft noise reductions by 2–4 dB depending on the fight stage, and during the ground operation by up to 5 dB.
Keywords: aircraft noise; propeller aeroacoustics; noise reduction technologies; ground operations noise; sound exposure level; ACARE Flightpath 2050 aircraft noise; propeller aeroacoustics; noise reduction technologies; ground operations noise; sound exposure level; ACARE Flightpath 2050
