FIELD: ventilation.
SUBSTANCE: invention concerns a blade for an industrial axial fan and an industrial axial fan comprising such a blade. In more detail, the present invention relates to a blade for an industrial axial fan comprising an attachment and an airfoil, said attachment connecting the airfoil to a hub and characterised in that said attachment has a stiffness and a stiffness distribution that allows the attachment to deform in a way to have at least an inflection point during the operation of the axial fan.
EFFECT: blade for an industrial axial fan is disclosed.
