Aeroacoustics
A recent growing interest in Urban Air Mobility (UAM) worldwide has led to the demand for physical analysis of the aerodynamic performance and aeroacoustic characteristics of electric Vertical Take-Off and Landing(eVTOL) rotorcraft. In UAM eVTOL rotorcraft, the smaller vortices generated from multiple propulsors complicately interact with lifting surfaces such as wings, fuselage, and propellers. Therefore, for the accurate performance and noise prediction of UAM eVTOL rotorcraft, vortices should be preserved with few dissipation, and their interactions must be modeled precisely. Aeroacoustic solver in AVDL calculated discrete-frequency noise by solving Ffowcs-Williams and Hawkings equation. Impermeable surface method is adopted for robust analysis of rotor noise. Broadband noise solver will be updated soon.
