This paper deals with stator efficiency improvement meant for automotive engine cooling fan systems. Four stators designed for a Valeo 380 mm rotor were manufactured and tested on a newly designed Valeo-Lemfi test rig. The following points are presented: • Overall performances of the 380 mm rotor. • Overall performances of the 380 mm rotor combined with a short chord stator. Inefficiency of such a design is shown: Slight deflection carried out by the stator is the cause of the slight gain of efficiency. • Overall performances of the 380 mm rotor combined to three long chord stators: this study confirms the gain of efficiency foreseen previously with the simplified radial equilibrium code VENTAX. • Steady velocities measured 33 mm downstream the various stage configurations: These measurements obtained by using a 5-holes probe show high deflection carried out by the long chord stators.
