Abstract
Noise characteristics from propellers in axial inflow conditions and steady blade loading have been largely studied in the past, with numerical and analytical methods spanning from low-fidelity models to high-fidelity simulations. However, fewer studies have addressed noise generation under unsteady or transient operating conditions. In practical applications, rotorcraft flight can be described as a sequence of equilibrium states connected by transitional maneuvers, characterized by unsteady and aperiodic effects. These conditions give rise to noise generation mechanisms that may significantly differ from those observed under stationary operation. In this seminar, a low-fidelity methodology for rotor noise prediction under unsteady operating conditions will be presented, highlighting both its strengths and its inherent limitations with respect to more accurate approaches.
