Abstract (en)
An axial air movement fan comprises a hub (1) with a plurality of elongate fan blades (3) extending generally radially outwardly therefrom, each blade (3) including at least one damping mass (11) secured to the fan blade to enable the mass to oscillate relative to the fan blade (3) in response to oscillatory flexing of the fan blade in a first plane, thereby to damp the flexing of the fan blade.
