Abstract
The fan impeller () comprises a hub () and blades () extending radially outward from the hub, the blades having a flattened airfoil profile cross section with a leading edge () and a trailing edge () between which a chord is defined. The blade () has a relative thickness that reached its maximum value (E) in the first quarter of the length of the chord measured from the leading edge (), the relative thickness being defined by the ratio between the thickness of the blade and the length of the chord. The invention finds an application particularly in motor vehicle engine cooling fan impellers.
