PHASE-SPECIFIC SEMI-EMPIRICAL AEROACOUSTIC NOISE MODELING OF A CARGO EVTOL UAV WITH CONSIDERATION OF A SIMPLIFIED URBAN FLYOVER CASE
I. Peleshok¹, M. Hornung¹; ¹Technical University of Munich, Germany
Mission-wide, flight-phase-specific semi-empirical noise source models are derived from flight-test measurements of a cargo eVTOL UAV. The approach enables mission-wide noise prediction and supports urban operational noise assessment. A simple urban flyover experiment reveals deviations between free-field and near-wall measurements, motivating reflection-aware extensions of the source models.
