The level of rotor noise is determined by geometry (thickness noise) of a flying vehicle and distributed blade loading (loading noise). Initially, the FW-H equation was obtained from Euler’s equations and does not depend on the viscosity of flow. In the present work the UH-1H helicopter is considered as a test case for numerical CFD simulation and comparison to experimental data. %Z https://katalog.ub.tu-freiberg.de/Record/ai-49-aHR0cDovL2R4LmRvaS5vcmcvMTAuMTA1MS9lcGpjb25mLzIwMTkyMTMwMjA0OA %U https://katalog.ub.tu-freiberg.de/Record/ai-49-aHR0cDovL2R4LmRvaS5vcmcvMTAuMTA1MS9lcGpjb25mLzIwMTkyMTMwMjA0OA
