摘要

The fan part (1a) has a support disk (22) for supporting fan blades (20) and rotated with respect to a stator part (4), along a longitudinal axis (2) of the fan part. Incident setting systems are associated with the corresponding blades. Each setting system is configured such that incidence of each blade varies, according to a cyclic setting law, based on an angular position of the blade with respect to the stator part along the axis. The setting law is periodic of a period P that is equal to division of 360 degree and n, where n corresponds to an integer greater or equal to one. An independent claim is also included for a turbojet engine comprising an aerodynamic fairing.
