Abstract
An aeronautical thruster of longitudinal axis has a hub, an annular row of unducted upstream rotor blades and an annular row of unducted downstream stator blades. Each downstream stator blade is of variable pitch, and at least one of the downstream stator blades is in a closed-pitch configuration relative to another of the downstream stator blades in that it has a pitch angle smaller than the pitch angle of the other downstream stator blade.
Claims21
An aeronautical thruster (10) of longitudinal axis (X) comprising:
- a hub (12),
- an annular row of unducted upstream rotor blades (14) and an annular row of unducted downstream stator blades (16), each downstream stator blade (16) being of variable pitch, and
- wherein at least one of the downstream stator blades (16) is in a closed-pitch configuration relative to another of the downstream stator blades (16) in that it has a pitch angle (γ) smaller than the pitch angle (γ) of the other downstream stator blade (16).
