Each auxiliary air deflector (26A, 26B) is integrated to the propeller such that the auxiliary air deflector is driven in rotation with the propeller, and is arranged in a swept volume by the blades during rotation of the propeller. The propeller has a peripheral ferrule (24) connecting free ends of the blades. The auxiliary air deflector (26B) radially projects towards the central unit from the ferrule.
