Rotor noise comprises harmonic features, related to the blade passing frequency, as well as broadband noise. Even though an acoustic spectrum yields a frequency-distribution of energy within an acoustic pressure signal, it does not reveal phase-relat

The present study reports a novel wavelet-based method aimed at separating the noise emitted by a single propeller into two contributions, tonal and broadband. An assessment using two different experimental investigations of propellers operating in d

A noise footprint prediction framework for propeller-driven aircraft which couples an aerodynamic model and several aeroacoustic models is presented in this study. The aerodynamic model is based on the blade element momentum theory, while the aeroaco
