AERONAUTICAL THRUSTER WITH IMPROVED AEROACOUSTICS

Aeronautical thruster (40) having a longitudinal axis (X) and comprising an upstream rotor row and a downstream stator row (16) having unducted blades (18). Two adjacent blades of the downstream stator row (16) have between them, about the longitudinal axis (X), an azimuthal spacing (Δθ), and at lea...

Summary:Aeronautical thruster (40) having a longitudinal axis (X) and comprising an upstream rotor row and a downstream stator row (16) having unducted blades (18). Two adjacent blades of the downstream stator row (16) have between them, about the longitudinal axis (X), an azimuthal spacing (Δθ), and at least some of these spacings differ from one another such that at least some of the blades of the downstream stator have a heterogeneous distribution about the longitudinal axis (X). Propulseur aéronautique (40) d'axe longitudinal (X) et comprenant une rangée rotorique amont et une rangée statorique aval (16) de pales (18) non carénées. Deux pales adjacentes de la rangée statorique aval (16) présentent entre elles, autour de l'axe longitudinal (X), un espacement azimutal (Δθ) dont certains au moins sont différents entre eux, de sorte que certaines au moins des pales du stator aval présentent une répartition hétérogène autour de l'axe longitudinal (X).
