Abstract
Within the flight test campaign PAVE 2004 a comprehensive data base of acoustic and flight parameters data has been constructed. It contains more than 240 flight procedures for stationary and maneuver flights. An acoustic source decomposition tool is applied on this data base to extract Fenestron and main rotor noise. The Fenestron noise emission is analysed according to various flight parameters and special features are identified.
