Abstract

A fan propeller comprises blades (14), each of which has a general profile of the aircraft wing type, with a leading edge (28) and a trailing edge (30), a neutral axis (32) and a span (36) between the leading edge (28) and the trailing edge (30) . According to one embodiment, the blade (14) has, on at least part of its length, a profile shaped such that the neutral axis (32) makes possible a point of contraflexure (34), and has two opposite concavities, i.e. a positive concavity (C1) between the leading edge (28) and the point of contraflexure (34), and a negative concavity (C2) between the point of contraflexure (34) and the trailing edge (30). Application to motor vehicles.
