Abstract
A comprehensive assessment of the noise generation and the acoustic impact of electric propulsion fans is an essential part of urban/regional aircraft development and can provide important guidance on design changes for increased acceptance. Experimental investigations at the CRAFT (Co/Counter Rotating Acoustic Fan Test rig) test facility provide important contributions, e.g. to reveal unexplored correlations between the often disturbed inflow and the acoustics of the fan, to provide realistic input for the assessment of auditory perception and to validate modelling approaches. The presentation gives an overview of current fan designs and the wide range of applications of the CRAFT test rig.
